After we left the _Vegas_, we had the gratification to be joined by the famous hunter and trapper, Mr. Joseph Walker, whom I have before mentioned, and who now became our guide. He had left California with the great caravan; and perceiving, from the signs along the trail, that there was a party of whites ahead, which he judged to be mine, he detached himself from the caravan, with eight men, (Americans,) and ran the gauntlet of the desert robbers, killing two, and getting some of the horses wounded, and succeeded in overtaking us. Nothing but his great knowledge of the country, great courage and presence of mind, and good rifles, could have brought him safe from such a perilous enterprise.

13th.--We remained one day at this noted place of rest and refreshment; and, resuming our progress in a northwestwardly direction, we descended into a broad valley, the water of which is tributary to Sevier lake. The next day we came in sight of the Wahsatch range of mountains on the right, white with snow, and here forming the southeast part of the Great Basin.

Sevier lake, upon the waters of which we now were, belonged to the system of lakes in the eastern part of the Basin--of which, the Great Salt lake, and its southern limb, the Utah lake, were the princ.i.p.al--towards the region of which we were now approaching. We traveled for several days in this direction, within the rim of the Great Basin, crossing little streams which bore to the left for Sevier lake; and plainly seeing, by the changed aspect of the country, that we were entirely clear of the desert, and approaching the regions which appertained to the system of the Rocky mountains. We met, in this traverse, a few mounted Utah Indians, in advance of their main body, watching the approach of the great caravan.

16th.--We reached a small salt lake, about seven miles long and one broad, at the northern extremity of which we encamped for the night. This little lake, which well merits its characteristic name, lies immediately at the base of the Wah-satch range, and nearly opposite a gap in that chain of mountains through which the Spanish trail pa.s.ses; and which, again falling upon the waters of the Colorado, and crossing that river, proceeds over a mountainous country to Santa Fe.

17th.--After 440 miles of traveling on a trail, which served for a road, we again found ourselves under the necessity of exploring a track through the wilderness. The Spanish trail had borne off to the southeast, crossing the Wah-satch range. Our course led to the northeast, along the foot of that range, and leaving it on the right. The mountain presented itself to us under the form of several ridges, rising one above the other, rocky, and wooded with pine and cedar; the last ridge covered with snow. Sevier river, flowing northwardly to the lake of the same name, collects its princ.i.p.al waters from this section of the Wah-satch chain. We had now entered a region of great pastoral promise, abounding with fine streams, the rich bunch-gra.s.s, soil that would produce wheat, and indigenous flax growing as if it had been sown. Consistent with the general character of its bordering mountains, this fertility of soil and vegetation does not extend far into the Great Basin. Mr. Joseph Walker, our guide, and who has more knowledge of these parts than any man I know, informed me that all the country to the left was unknown to him, and that even the _Digger_ tribes, which frequented Lake Sevier, could tell him nothing about it.

20th.--We met a band of Utah Indians, headed by a well-known chief, who had obtained the American or English name of Walker, by which he is quoted and well known. They were all mounted, armed with rifles, and used their rifles well. The chief had a fusee, which he carried slung, in addition to his rifle. They were journeying slowly towards the Spanish trail, to levy their usual tribute upon the great California caravan. They were robbers of a higher order than those of the desert. They conducted their depredations with form, and under the color of trade and toll, for pa.s.sing through their country. Instead of attacking and killing, they affect to purchase--taking the horses they like, and giving something nominal in return. The chief was quite civil to me. He was personally acquainted with his namesake, our guide, who made my name known to him. He knew of my expedition of 1842; and, as tokens of friendship, and proof that we had met, proposed an interchange of presents. We had no great store to choose out of; so he gave me a Mexican blanket, and I gave him a very fine one which I had obtained at Vancouver.

23d.--We reached Sevier river--the main tributary of the lake of the same name--which, deflecting from its northern course, here breaks from the mountains to enter the lake. It was really a fine river, from eight to twelve feet deep; and after searching in vain for a fordable place, we made little boats (or rather rafts) out of bulrushes, and ferried across.

These rafts are readily made, and give a good conveyance across a river.

The rushes are bound in bundles, and tied hard; the bundles are tied down upon poles, as close as they can be pressed, and fashioned like a boat, in being broader in the middle and pointed at the ends. The rushes, being tubular and jointed, are light and strong. The raft swims well, and is shoved along by poles, or paddled, or pushed and pulled by swimmers, or drawn by ropes. On this occasion, we used ropes--one at each end--and rapidly drew our little float backwards and forwards from sh.o.r.e to sh.o.r.e.

The horses swam. At our place of crossing, which was the most northern point of its bend, the lat.i.tude was 39 22' 19". The banks sustained the character for fertility and vegetation which we had seen for some days.

The name of this river and lake was an indication of our approach to regions of which our people had been the explorers. It was probably named after some American trapper or hunter, and was the first American name we had met with since leaving the Columbia river. From the Dalles to the point where we turned across the Sierra Nevada, near 1,000 miles, we heard Indian names, and the greater part of the distance none; from Nueva Helvetia (Sacramento) to _las Vegas de Santa Clara_, about 1,000 more, all were Spanish; from the Mississippi to the Pacific, French and American or English were intermixed; and this prevalence of names indicates the national character of the first explorers.

We had here the misfortune to lose one of our people, Francois Badeau, who had been with me on both expeditions; during which he had always been one of my most faithful and efficient men. He was killed in drawing towards him a gun by the muzzle; the hammer being caught, discharged the gun, driving the ball through his head. We buried him on the banks of the river.

Crossing the next day a slight ridge along the river, we entered a handsome mountain valley covered with fine gra.s.s, and directed our course towards a high snowy peak, at the foot of which lay the Utah lake. On our right was a bed of high mountains, their summits covered with snow, const.i.tuting the dividing ridge between the Basin waters and those of the Colorado. At noon we fell in with a party of Utah Indians coming out of the mountain, and in the afternoon encamped on a tributary to the lake, which is separated from the waters of the Sevier by very slight dividing grounds.

Early the next day we came in sight of the lake; and, as we descended to the broad bottoms of the Spanish fork, three hors.e.m.e.n were seen galloping towards us, who proved to be Utah Indians--scouts from a village, which was encamped near the mouth of the river. They were armed with rifles, and their horses were in good condition. We encamped near them, on the Spanish fork, which is one of the princ.i.p.al tributaries to the lake. Finding the Indians troublesome, and desirous to remain here a day, we removed the next morning farther down the lake and encamped on a fertile bottom near the foot of the same mountainous ridge which borders the Great Salt lake, and along which we had journeyed the previous September. Here the princ.i.p.al plants in bloom were two, which were remarkable as affording to the Snake Indians--the one an abundant supply of food, and the other the most useful among the applications which they use for wounds. These were the kooyah plant, growing in fields of extraordinary luxuriance, and _convollaria stellata_, which, from the experience of Mr. Walker, is the best remedial plant known among these Indians. A few miles below us was another village of Indians, from which we obtained some fish--among them a few salmon trout, which were very much inferior in size to those along the Californian mountains. The season for taking them had not yet arrived; but the Indians were daily expecting them to come up out of the lake.

We had now accomplished an object we had in view when leaving the Dalles of the Columbia in November last: we had reached the Utah lake; but by a route very different from the one we had intended, and without sufficient time remaining to make the examinations which we desired. It is a lake of note in this country, under the dominion of the Utahs, who resort to it for fish. Its greatest breadth is about fifteen miles, stretching far to the north, narrowing as it goes, and connecting with the Great Salt lake.

This is the report, which I believe to be correct; but it is fresh water, while the other is not only salt, but a saturated solution of salt; and here is a problem which requires to be solved. It is almost entirely surrounded by mountains, walled on the north and east by a high and snowy range, which supplies to it a fan of tributary streams. Among these, the princ.i.p.al river is the _Timpan-ogo_--signifying Rock river--a name which the rocky grandeur of its scenery, remarkable even in this country of rugged mountains, has obtained for it from the Indians. In the Utah language, _og-wah-be_, the term for river, when coupled with other words in common conversation, is usually abbreviated to _ogo; timpan_ signifying rock. It is probable that this river furnished the name which on the older maps has been generally applied to the Great Salt lake; but for this I have preferred a name which will be regarded as highly characteristic, restricting to the river the descriptive term Timpan-ogo, and leaving for the lake into which it flows the name of the people who reside on its sh.o.r.es, and by which it is known throughout the country.

The volume of water afforded by the Timpan-ogo is probably equal to that of the Sevier river; and, at the time of our visit, there was only one place in the lake-valley at which the Spanish fork was fordable. In the cove of the mountains along its eastern sh.o.r.e, the lake is bordered by a plain, where the soil is generally good, and in greater part fertile; watered by a delta of prettily timbered streams. This would be an excellent locality for stock-farms; it is generally covered with good bunch-gra.s.s, and would abundantly produce the ordinary grains.

In arriving at the Utah lake, we had completed an immense circuit of twelve degrees diameter north and south, and ten degrees east and west; and found ourselves, in May, 1844, on the same sheet of water which we had left in September, 1843. The Utah is the southern limb of the Great Salt lake; and thus we had seen that remarkable sheet of water both at its northern and southern extremity, and were able to fix its position at these two points. The circuit which we had made, and which had cost us eight months of time, and 3,500 miles of traveling, had given us a view of Oregon and of North California from the Rocky mountains to the Pacific ocean, and of the two princ.i.p.al streams which form bays or harbors on the coast of that sea. Having completed this circuit, and being now about to turn the back upon the Pacific slope of our continent, and to recross the Rocky mountains, it is natural to look back upon our footsteps, and take some brief view of the leading features and general structure of the country we had traversed. These are peculiar and striking, and differ essentially from the Atlantic side of the country. The mountains all are higher, more numerous, and more distinctly defined in their ranges and directions; and, what is so contrary to the natural order of formations, one of these ranges, which is near the coast, (the Sierra Nevada and the Coast Range,) presents higher elevations and peaks than any which are to be found in the Rocky mountains themselves. In our eight months' circuit, we were never out of sight of snow; and the Sierra Nevada, where we crossed it, was near 2,000 feet higher than the South Pa.s.s in the Rocky mountains. In height, these mountains greatly exceed those of the Atlantic side, constantly presenting peaks which enter the region of eternal snow; and some of them volcanic, and in a frequent state of activity. They are seen at great distances, and guide the traveler in his course.

The course and elevation of these ranges give direction to the rivers and character to the coast. No great river does, or can, take its rise below the Cascade and Sierra Nevada range; the distance to the sea is too short to admit of it. The rivers of the San Francis...o...b..y, which are the largest after the Columbia, are local to that bay, and lateral to the coast, having their sources about on a line with the Dalles of the Columbia, and running each in a valley of its own, between the Coast range and the Cascade and Sierra Nevada range. The Columbia is the only river which traverses the whole breadth of the country, breaking through all the ranges, and entering the sea. Drawing its waters from a section of ten degrees of lat.i.tude in the Rocky mountains, which are collected into one stream by three main forks (Lewis's, Clark's, and the North fork) near the centre of the Oregon valley, this great river thence proceeds by a single channel to the sea, while its three forks lead each to a pa.s.s in the mountains, which opens the way into the interior of the continent. This fact in relation to the rivers of this region, gives an immense value to the Columbia. Its mouth is the only inlet and outlet to and from the sea: its three forks lead to the pa.s.ses in the mountains: it is, therefore, the only line of communication between the Pacific and the interior of North America; and all operations of war or commerce, of national or social intercourse, must be conducted upon it. This gives it a value beyond estimation, and would involve irreparable injury if lost. In this unity and concentration of its waters, the Pacific side of our continent differs entirely from the Atlantic side, where the waters of the Alleghany mountains are dispersed into many rivers, having their different entrances into the sea, and opening many lines of communication with the interior.

The Pacific coast is equally different from that of the Atlantic. The coast of the Atlantic is low and open, indented with numerous bays, sounds, and river estuaries, accessible everywhere, and opening by many channels into the heart of the country. The Pacific coast, on the contrary, is high and compact, with few bays, and but one that opens into the heart of the country. The immediate coast is what the seamen call _iron-bound_. A little within, it is skirted by two successive ranges of mountains, standing as ramparts between the sea and the interior of the country; and to get through which there is but one gate, and that narrow and easily defended. This structure of the coast, backed by these two ranges of mountains, with its concentration and unity of waters, gives to the country an immense military strength, and will probably render Oregon the most impregnable country in the world.

Differing so much from the Atlantic side of our continent, in coast, mountains, and rivers, the Pacific side differs from it in another most rare and singular feature--that of the Great Interior Basin, of which I have so often spoken, and the whole form and character of which I was so anxious to ascertain. Its existence is vouched for by such of the American traders and hunters as have some knowledge of that region; the structure of the Sierra Nevada range of mountains requires it to be there; and my own observations confirm it. Mr. Joseph Walker, who is so well acquainted in these parts, informed me that, from the Great Salt lake west, there was a succession of lakes and rivers which have no outlet to the sea, nor any connection with the Columbia, or with the Colorado of the Gulf of California. He described some of these lakes as being large, with numerous streams, and even considerable rivers falling into them. In fact, all concur in the general report of these interior rivers and lakes; and, for want of understanding the force and power of evaporation, which so soon establishes an equilibrium between the loss and supply of waters, the fable of whirlpools and subterraneous outlets has gained belief, as the only imaginable way of carrying off the waters which have no visible discharge. The structure of the country would require this formation of interior lakes; for the waters which would collect between the Rocky mountains and the Sierra Nevada, not being able to cross this formidable barrier, nor to get to the Columbia or the Colorado, must naturally collect into reservoirs, each of which would have its little system of streams and rivers to supply it. This would be the natural effect; and what I saw went to confirm it. The Great Salt lake is a formation of this kind, and quite a large one; and having many streams, and one considerable river, 400 or 500 miles long, falling into it. This lake and river I saw and examined myself; and also saw the Wah-satch and Bear River mountains, which enclose the waters of the lake on the east, and const.i.tute, in that quarter, the rim of the Great Basin. Afterwards, along the eastern base of the Sierra Nevada, where we traveled for 42 days, I saw the line of lakes and rivers which lie at the foot of that Sierra; and which Sierra is the western rim of the Basin. In going down Lewis's fork and the main Columbia, I crossed only inferior streams coming in from the left, such as could draw their water from a short distance only; and I often saw the mountains at their heads white with snow,--which, all accounts said, divided the waters of the _desert_ from those of the Columbia, and which could be no other than the range of mountains which form the rim of the Basin on its northern side. And in returning from California along the Spanish trail, as far as the head of the Santa Clara fork of the Rio Virgen, I crossed only small streams making their way south to the Colorado, or lost in sand, (as the Mo-hah-ve;) while to the left, lofty mountains, their summits white with snow, were often visible, and which must have turned water to the north as well as to the south, and thus const.i.tuted, on this part, the southern rim of the Basin. At the head of the Santa Clara fork, and in the Vegas de Santa Clara, we crossed the ridge which parted the two systems of waters. We entered the Basin at that point, and have traveled in it ever since; having its southeastern rim (the Wah-satch mountain) on the right, and crossing the streams which flow down into it. The existence of the Basin is, therefore, an established fact in my mind: its extent and contents are yet to be better ascertained.

It cannot be less than 400 or 500 miles each way, and must lie princ.i.p.ally in the Alta California; the demarcation lat.i.tude of 42 probably cutting a segment from the north part of the rim. Of its interior, but little is known. It is called a _desert_, and, from what I saw of it, sterility may be its prominent characteristic; but where there is so much water, there must be some _oasis_. The great river, and the great lake, reported, may not be equal to the report; but where there is so much snow, there must be streams; and where there is no outlet, there must be lakes to hold the acc.u.mulated waters, or sands to swallow them up. In this eastern part of the Basin, containing Sevier, Utah, and the Great Salt lakes, and the rivers and creeks falling into them, we know there is good soil and good gra.s.s, adapted to civilized settlements. In the western part, on Salmon Trout river, and some other streams, the same remark may be made.

The contents of this great Basin are yet to be examined. That it is peopled, we know; but miserably and spa.r.s.ely. From all that I heard and saw, I should say that humanity here appeared in its lowest form, and in its most elementary state. Dispersed in single families; without fire- arms; eating seeds and insects; digging roots, (and hence their name,)-- such is the condition of the greater part. Others are a degree higher, and live in communities upon some lake or river that supplies fish, and from which they repulse the miserable _Digger_. The rabbit is the largest animal known in this desert; its flesh affords a little meat; and their bag-like covering is made of its skins. The wild sage is their only wood, and here it is of extraordinary size--sometimes a foot in diameter, and six or eight feet high. It serves for fuel, for building material, for shelter to the rabbits, and for some sort of covering for the feet and legs in cold weather. Such are the accounts of the inhabitants and productions of the Great Basin; and which, though imperfect, must have some foundation, and excite our desire to know the whole.

The whole idea of such a desert, and such a people, is a novelty in our country, and excites Asiatic, not American ideas. Interior basins, with their own systems of lakes and rivers, and often sterile, are common enough in Asia; people still in the elementary state of families, living in deserts, with no other occupation than the mere animal search for food, may still be seen in that ancient quarter of the globe; but in America such things are new and strange, unknown and unsuspected, and discredited when related. But I flatter myself that what is discovered, though not enough to satisfy curiosity, is sufficient to excite it, and that subsequent explorations will complete what has been commenced.

This account of the Great Basin, it will be remembered, belongs to the Alta California, and has no application to Oregon, whose capabilities may justify a separate remark. Referring to my journal for particular descriptions, and for sectional boundaries between good and bad districts, I can only say, in general and comparative terms, that, in that branch of agriculture which implies the cultivation of grains and staple crops, it would be inferior to the Atlantic States, though many parts are superior for wheat; while in the rearing of flocks and herds it would claim a high place. Its grazing capabilities are great; and even in the indigenous gra.s.s now there, an element of individual and national wealth may be found. In fact, the valuable gra.s.ses begin within one hundred and fifty miles of the Missouri frontier, and extend to the Pacific ocean. East of the Rocky mountains, it is the short curly gra.s.s, on which the buffalo delights to feed, (whence its name of buffalo,) and which is still good when dry and apparently dead. West of those mountains it is a larger growth, in cl.u.s.ters, and hence called bunch-gra.s.s, and which has a second or fall growth. Plains and mountains both exhibit them; and I have seen good pasturage at an elevation of ten thousand feet. In this spontaneous product the trading or traveling caravans can find subsistence for their animals; and in military operations any number of cavalry may be moved, and any number of cattle may be driven; and thus men and horses be supported on long expeditions, and even in winter, in the sheltered situations.

Commercially, the value of the Oregon country must be great, washed as it is by the North Pacific ocean--fronting Asia--producing many of the elements of commerce--mild and healthy in its climate--and becoming, as it naturally will, a thoroughfare for the East India and China trade.

Turning our faces once more eastward, on the morning of the 27th we left the Utah lake, and continued for two days to ascend the Spanish fork, which is dispersed in numerous branches among very rugged mountains, which afford few pa.s.ses, and render a familiar acquaintance with them necessary to the traveler. The stream can scarcely be said to have a valley, the mountains rising often abruptly from the water's edge; but a good trail facilitated our traveling, and there were frequent bottoms, covered with excellent gra.s.s. The streams are prettily and variously wooded; and everywhere the mountain shows gra.s.s and timber.

At our encampment on the evening of the 28th, near the head of one of the branches we had ascended, strata of bituminous limestone were displayed in an escarpment on the river bluffs, in which were contained a variety of fossil sh.e.l.ls of new species.

It will be remembered, that in crossing this ridge about 120 miles to the northward in August last, strata of fossiliferous rock were discovered, which have been referred to the oolitic period; it is probable that these rocks also belong to the same formation.

A few miles from this encampment we reached the bed of the stream, and crossing, by an open and easy pa.s.s, the dividing ridge which separates the waters of the Great Basin from those of the Colorado, we reached the head branches of one of its larger tributaries, which, from the decided color of its waters, has received the name of White river. The snows of the mountains were now beginning to melt, and all the little rivulets were running by in rivers, and rapidly becoming difficult to ford. Continuing a few miles up a branch of White river, we crossed a dividing ridge between its waters and those of _Uintah_. The approach to the pa.s.s, which is the best known to Mr. Walker, was somewhat difficult for packs, and impracticable for wagons--all the streams being shut in by narrow ravines, and the narrow trail along the steep hill-sides allowing the pa.s.sage of only one animal at a time. From the summit we had a fine view of the snowy Bear River range, and there were still remaining beds of snow on the cold sides of the hills near the pa.s.s. We descended by a narrow ravine, in which was rapidly gathered a little branch of the Uintah, and halted to noon about 1,500 feet below the pa.s.s, at an elevation, by the boiling point, of 6,900 feet above the sea.

The next day we descended along the river, and about noon reached a point where three forks come together. Fording one of these with some difficulty, we continued up the middle branch, which, from the color of its waters, is named the Red river. The few pa.s.ses, and extremely rugged nature of the country, give to it great strength, and secure the Utahs from the intrusion of their enemies. Crossing in the afternoon a somewhat broken highland, covered in places with fine gra.s.ses, and with cedar on the hill-sides, we encamped at evening on another tributary to the _Uintah_, called the _d.u.c.h.esne_ fork. The water was very clear, the stream not being yet swollen by the melting snows, and we forded it without any difficulty. It is a considerable branch, being spread out by islands, the largest arm being about a hundred feet wide, and the name it bears is probably that of some old French trapper.

The next day we continued down the river, which we were twice obliged to cross; and, the water having risen during the night, it was almost everywhere too deep to be forded. After traveling about sixteen miles, we encamped again on the left bank.

I obtained here an occultation of _Scorpii_ at the dark limb of the moon, which gives for the longitude of the place 112 18' 30", and the lat.i.tude 40 18' 53".

JUNE.

1st.--We left to-day the d.u.c.h.esne fork, and, after traversing a broken country for about sixteen miles, arrived at noon at another considerable branch, a river of great velocity, to which the trappers have improperly given the name of Lake fork. The name applied to it by the Indians signifies great swiftness, and is the same which they use to express the speed of a racehorse. It is spread out in various channels over several hundred yards, and is everywhere too deep and swift to be forded. At this season of the year, there is an uninterrupted noise from the large rocks which are rolled along the bed. After infinite difficulty, and the delay of a day, we succeeded in getting the stream bridged, and got over with the loss of one of our animals. Continuing our route across a broken country, of which the higher parts were rocky and timbered with cedar, and the lower parts covered with good gra.s.s, we reached, on the afternoon of the 3d, the Uintah fort, a trading-post belonging to Mr. A. Roubideau, on the princ.i.p.al fork of the Uintah river. We found the stream nearly as rapid and difficult as the Lake fork, divided into several channels, which were too broad to be bridged. With the aid of guides from the fort, we succeeded, with very great difficulty, in fording it, and encamped near the fort, which is situated a short distance above the junction of two branches which make the river.

By an immersion of the first satellite, (agreeing well with the result of the occultation observed at the d.u.c.h.esne fork,) the longitude of the post is 109 56' 42", the lat.i.tude 40 27' 45".

It has a motley garrison of Canadian and Spanish _engages_ and hunters, with the usual number of Indian women. We obtained a small supply of sugar and coffee, with some dried meat and a cow, which was a very acceptable change from the _pinoli_ on which we had subsisted for some weeks past. I strengthened my party at this place by the addition of Auguste Archambeau, an excellent voyageur and hunter, belonging to the cla.s.s of Carson and G.o.dey.

On the morning of the 5th we left the fort [Footnote: This fort was attacked and taken by a band of the Utah Indians since we pa.s.sed it, and the men of the garrison killed--the women carried off. Mr. Roubideau, a trader of St. Louis, was absent, and so escaped the fate of the rest.] and the Uintah river, and continued our road over a broken country, which afforded, however, a rich addition to our botanical collection; and, after a march of 25 miles, were again checked by another stream, called Ashley's fork, where we were detained until noon of the next day.

An immersion of the second satellite gave for this place a longitude of 109 27' 07", the lat.i.tude, by observation, being 40 28' 07".

In the afternoon of the next day we succeeded in finding a ford; and, after traveling 15 miles, encamped high up on the mountain-side, where we found excellent and abundant gra.s.s, which we had not hitherto seen. A new species of _elymus_, which had a purgative and weakening effect upon the animals, had occurred abundantly since leaving the fort. From this point, by observation 7,300 feet above the sea, we had a view of Colorado below, shut up amongst rugged mountains, and which is the recipient of all the streams we had been crossing since we pa.s.sed the rim of the Great Basin at the head of the Spanish fork.

On the 7th we had a pleasant but long day's journey, through beautiful little valleys and a high mountain country, arriving about evening at the verge of a steep and rocky ravine, by which we descended to "_Brown's hole_." This is a place well known to trappers in the country, where the canons through which the Colorado runs expand into a narrow but pretty valley, about 16 miles in length. The river was several hundred yards in breadth, swollen to the top of its banks, near to which it was in many places 15 to 20 feet deep. We repaired a skin-boat which had been purchased at the fort, and, after a delay of a day, reached the opposite banks with much less delay than had been encountered on the Uintah waters.

According to information, the lower end of the valley is the most eastern part of the Colorado; and the lat.i.tude of our encampment, which was opposite to the remains of an old fort on the left bank of the river, was 40 46' 27", and, by observation, the elevation above the sea 5,150 feet.

The bearing to the entrance of the canon below was south 20 east. Here the river enters between lofty precipices of red rock, and the country below is said to a.s.sume a very rugged character, the river and its affluents pa.s.sing through canons which forbid all access to the water.

This sheltered little valley was formerly a favorite wintering ground for the trappers, as it afforded them sufficient pasturage for their animals, and the surrounding mountains are well stocked with game.

We surprised a flock of mountain sheep as we descended to the river, and our hunters killed several. The bottoms of a small stream called Vermilion creek, which enters the left bank of the river a short distance below our encampment, were covered abundantly with _F. vermicularis_, and other chenopodiaceous shrubs. From the lower end of Brown's hole we issued by a remarkably dry canon, fifty or sixty yards wide, and rising, as we advanced, to the height of six or eight hundred feet. Issuing from this, and crossing a small green valley, we entered another rent of the same nature, still narrower than the other, the rocks on either side rising in nearly vertical precipices perhaps 1,500 feet in height. These places are mentioned, to give some idea of the country lower down on the Colorado, to which the trappers usually apply the name of a canon country. The canon opened upon a pond of water, where we halted to noon. Several flocks of mountain sheep were here among the rocks, which rung with volleys of small-arms. In the afternoon we entered upon an ugly, barren, and broken country, corresponding well with that we had traversed a few degrees north, on the same side of the Colorado. The Vermilion creek afforded us brackish water and indifferent gra.s.s for the night.

A few scattered cedar-trees were the only improvement of the country on the following day; and at a little spring of bad water, where we halted at noon, we had not even the shelter of these from the hot rays of the sun.

At night we encamped in a fine grove of cottonwood-trees, on the banks of the Elk Head river, the princ.i.p.al fork of the Yampah river, commonly called by the trappers the Bear river. We made here a very strong fort, and formed the camp into vigilant guards. The country we were now entering was constantly infested by war parties of the Sioux and other Indians, and is among the most dangerous war-grounds in the Rocky mountains; parties of whites having been repeatedly defeated on this river.

On the 11th we continued up the river, which is a considerable stream, fifty to a hundred yards in width, handsomely and continuously wooded with groves of the narrow-leaved cottonwood, _populus angustifolia_; with these were thickets of willow, and _grain du boeuf_. The characteristic plant along the river is _F. vermicularis_, which generally covers the bottoms; mingled with this are saline shrubs and artemisia. The new variety of gra.s.s which we had seen on leaving the Uintah fort had now disappeared. The country on either side was sandy and poor, scantily wooded with cedars, but the river bottoms afforded good pasture. Three antelopes were killed in the afternoon, and we encamped a little below a branch of the river, called St. Vrain's fork. A few miles above was the fort at which Frapp's party had been defeated two years since; and we pa.s.sed during the day a place where Carson had been fired upon so close that one of the men had five bullets through his body.

Leaving this river the next morning, we took our way across the hills, where every hollow had a spring of running water with good gra.s.s.

Yesterday and to-day we had before our eyes the high mountains which divide the Pacific from the Mississippi waters; and entering here among the lower spurs or foot-hills of the range, the face of the country began to improve with a magical rapidity. Not only the river bottoms, but the hills were covered with gra.s.s; and among the usual varied flora of the mountain region, these were occasionally blue with the showy bloom of a _lupinus_. In the course of the morning we had the first glad view of buffalo, and welcomed the appearance of two old bulls with as much joy as if they had been messengers from home; and when we descended to noon on St. Vrain's fork, an affluent of Green river, the hunters brought in mountain sheep and the meat of two fat bulls. Fresh entrails in the river showed us that there were Indians above, and at evening, judging it unsafe to encamp in the bottoms, which were wooded only with willow thickets, we ascended to the spurs above, and forted strongly in a small aspen grove, near to which was a spring of cold water. The hunters killed two fine cows near the camp. A band of elk broke out of a neighboring grove; antelopes were running over the hills; and on the opposite river-plains herds of buffalo were raising clouds of dust. The country here appeared more variously stocked with game than any part of the Rocky mountains we had visited; and its abundance is owing to the excellent pasturage, and its dangerous character as a war-ground.

13th.--There was snow here near our mountain camp, and the morning was beautiful and cool. Leaving St. Vrain's fork, we took our way directly towards the summit of the dividing ridge. The bottoms of the streams and level places were wooded with aspens; and as we neared the summit, we entered again the piny region. We had a delightful morning's ride, the ground affording us an excellent bridle-path, and reached the summit towards mid-day, at an elevation of 8,000 feet. With joy and exultation we saw ourselves once more on the top of the Rocky mountains, and beheld a little stream taking its course towards the rising sun. It was an affluent of the Platte, called Pullam's fork, and we descended to noon upon it. It is a pretty stream, twenty yards broad, and bears the name of a trapper who, some years since, was killed here by the _Gros Ventre_ Indians.

Issuing from the pines in the afternoon we saw spread out before us the valley of the Platte, with the pa.s.s of the Medicine b.u.t.te beyond, and some of the Sweet Water mountains; but a smoky haziness in the air entirely obscured the Wind River chain.

We were now about two degrees south of the South Pa.s.s, and our course home would have been eastwardly; but that would have taken us over ground already examined, and therefore without the interest that would excite curiosity. Southwardly there were objects worthy to be explored, to wit: the approximation of the head-waters of three different rivers--the Platte, the Arkansas, and the Grand River fork of the Rio Colorado of the Gulf of California; the pa.s.sages at the heads of these rivers; and the three remarkable mountain coves, called Parks, in which they took their rise. One of these Parks was, of course, on the western side of the dividing ridge; and a visit to it would once more require us to cross the summit of the Rocky mountains to the west, and then to recross to the east, making in all, with the transit we had just accomplished, three crossings of that mountain in this section of its course. But no matter.

The coves, the heads of the rivers, the approximation of their waters, the practicability of the mountain pa.s.ses, and the locality of the three Parks, were all objects of interest, and, although well known to hunters and trappers, were unknown to science and to history. We therefore changed our course, and turned up the valley of the Platte instead of going down it.

We crossed several small affluents, and again made a fortified camp in a grove. The country had now became very beautiful--rich in water, gra.s.s, and game; and to these were added the charm of scenery and pleasant weather.

14th.--Our route this morning lay along the foot of the mountain, over the long low spurs which sloped gradually down to the river, forming the broad valley of the Platte. The country is beautifully watered. In almost every hollow ran a clear, cool, mountain stream; and in the course of the morning we crossed seventeen, several of them being large creeks, forty to fifty feet wide, with a swift current, and tolerably deep. These were variously wooded with groves of aspen and cottonwood, with willow, cherry, and other shrubby trees. Buffalo, antelope, and elk, were frequent during the day; and, in their abundance; the latter sometimes reminded us slightly of the Sacramento valley.
