Our route luring the afternoon was a little rough, being (in the direction we had taken) over a volcanic plain, where our progress was sometimes obstructed by fissures, and black beds, composed of fragments of the rock. On both sides, the mountains appeared very broken, but tolerably well timbered.
Crossing a point of ridge which makes in to the river, we fell upon it again before sunset, and encamped on the right bank, opposite to the encampment of three lodges of Snake Indians. They visited us during the evening, and we obtained from them a small quantity of roots of different kinds, in exchange for goods. Among them was a sweet root of very pleasant flavor, having somewhat the taste of preserved quince. My endeavors to become acquainted with the plants which furnish to the Indians a portion of their support, were only gradually successful, and after long and persevering attention; and even after obtaining, I did not succeed in preserving them until they could be satisfactorily determined. In this portion of the journey, I found this particular root cut up into small pieces, that it was only to be identified by its taste, when the bulb was met with in perfect form among the Indians lower down on the Columbia, among whom it is the highly celebrated kamas. It was long afterwards, on our return through Upper California, that I found the plant itself in bloom, which I supposed to furnish the kamas root, (camassia esculenta.) The root diet had a rather mournful effect at the commencement, and one of the calves was killed this evening for food. The animals fared well on rushes.
27th.--The morning was cloudy, with appearance of rain, and the thermometer at sunrise at 29°. Making an unusually early start, we crossed the river at a good ford; and, following for about three hours a trail which led along the bottom, we entered a labyrinth of hills below the main ridge, and halted to noon in the ravine of a pretty little stream, timbered with cottonwood of a large size, ash-leaved maple, with cherry and other shrubby trees. The hazy weather, which had prevented any very extended views since entering the Green River valley, began now to disappear. There was a slight rain in the earlier part of the day, and at noon, when the thermometer had risen to 79.5°, we had a bright sun, with blue sky and scattered cumuli. According to the barometer, our halt there among the hills was at an elevation of 5,320 feet. Crossing a dividing ridge in the afternoon, we followed down another little Bear River tributary, to the point where it emerged on an open green flat among the hills, timbered with groves, and bordered with cane thickets, but without water. A pretty little rivulet coming out of the hillside, and overhung by tall flowering plants of a species I had not hitherto seen, furnished us with a good camping-place. The evening was cloudy, the temperature at sunset 69°, and the elevation 5,140 feet. Among the plants occurring along the road during the day, epinettes des prairies (grindelia squarraso) was in considerable abundance, and is among the very few plants remaining in bloom--the whole country having now an autumnal appearance, in the crisp and yellow plants, and dried-up grasses. Many cranes were seen during the day, with a few antelope, very shy and wild.
28th.--During the night we had a thunder-storm, with moderate rain, which has made the air this morning very clear, the thermometer being at 55°. Leaving our encampment at the Cane spring, and quitting the trail on which we had been traveling, and which would probably have afforded us a good road to the lake, we crossed some very deep ravines, and, in about an hour's traveling, again reached the river. We were now in a valley five or six miles wide, between mountain ranges, which, about thirty miles below, appeared to close up and terminate the valley, leaving for the river only a very narrow pass, or canon, behind which we imagined we would find the broad waters of the lake. We made the usual halt at the mouth of a small clear stream, having a slightly mineral taste, (perhaps of salt,) 4,760 feet above the gulf. In the afternoon we climbed a very steep sandy hill; and after a slow and winding day's march of 27 miles, encamped at a slough on the river. There were great quantities of geese and, ducks, of which only a few were shot; the Indians having probably made them very wild. The men employed themselves in fishing but caught nothing. A skunk, (mephitis Americana,) which was killed in the afternoon, made a supper for one of the messes. The river is bordered occasionally with fields of cane, which we regarded as an indication of our approach to a lake-country. We had frequent showers of rain during the night, with thunder.
29th.--The thermometer at sunrise was 54°, with air from the NW., and dark rainy clouds moving on the horizon; rain squalls and bright sunshine by intervals. I rode ahead with Basil to explore the country, and, continuing about three miles along the river, turned directly off on a trail running towards three marked gaps in the bordering range, where the mountains appeared cut through their bases, towards which the river plain rose gradually. Putting our horses into a gallop on some fresh tracks which showed very plainly in the wet path, we came suddenly upon a small party of Shoshonee Indians, who had fallen into the trail from the north. We could only communicate by signs; but they made us understand that the road through the chain was a very excellent one, leading into a broad valley which ran to the southward. We halted to noon at what may be called the gate of the pass; on either side of which were huge mountains of rock, between which stole a little pure water stream, with a margin just sufficiently large for our passage. From the river, the plain had gradually risen to an altitude of 5,500 feet, and, by meridian observation, the latitude of the entrance was 42°.
In the interval of our usual halt, several of us wandered along up the stream to examine the pass more at leisure. Within the gate, the rocks receded a little back, leaving a very narrow, but most beautiful valley, through which the little stream wound its way, hidden by the different kinds of trees and shrubs--aspen, maple, willow, cherry, and elder; a fine verdure of smooth short grass spread over the remaining space to the bare sides of the rocky walls. These were of a blue limestone, which constitutes the mountain here; and opening directly on the grassy bottom were several curious caves, which appeared to be inhabited by root- diggers. On one side was gathered a heap of leaves for a bed, and they were dry, open, and pleasant. On the roofs of the caves I remarked bituminous exudations from the rock.
The trail was an excellent one for pack-horses; but as it sometimes crossed a shelving point, to avoid the shrubbery we were obliged in several places to open a road for the carriage through the wood. A squaw on horseback, accompanied by five or six dogs, entered the pass in the afternoon; but was too much terrified at finding herself in such unexpected company to make any pause for conversation, and hurried off at a good pace--being, of course, no further disturbed than by an accelerating shout. She was well and showily dressed, and was probably going to a village encamped somewhere near, and evidently did not belong to the tribe of root-diggers. We now had entered a country inhabited by these people; and as in the course of the voyage we shall frequently meet with them in various stages of existence, it will be well to inform you that, scattered over the great region west of the Rocky mountains, and south of the Great Snake river, are numerous Indians whose subsistence is almost solely derived from roots and seeds, and such small animals as chance and great good fortune sometimes bring within their reach. They are miserably poor, armed only with bows and arrows, or clubs; and, as the country they inhabit is almost destitute of game, they have no means of obtaining better arms. In the northern part of the region just mentioned, they live generally in solitary families; and farther to the south they are gathered together in villages. Those who live together in villages, strengthened by association, are in exclusive possession of the more genial and richer parts of the country; while the others are driven to the ruder mountains, and to the more inhospitable parts of the country. But by simply observing, in accompanying us along our road, you will become better acquainted with these people than we could make you in any other than a very long description, and you will find them worthy of your interest.
Roots, seeds, and grass, every vegetable that affords any nourishment, and every living animal thing, insect or worm, they eat. Nearly approaching to the lower animal creation, their sole employment is to obtain food; and they are constantly occupied in struggling to support existence.
The most remarkable feature of the pass is the Standing rock, which has fallen from the cliffs above, and standing perpendicularly near the middle of the valley, presents itself like a watch-tower in the pass. It will give you a tolerably correct idea of the character of the scenery in this country, where generally the mountains rise abruptly up from comparatively unbroken plains and level valleys; but it will entirely fail in representing the picturesque beauty of this delightful place, where a green valley, full of foliage and a hundred yards wide, contrasts with naked crags that spire up into a blue line of pinnacles 3,000 feet above, sometimes crested with cedar and pine, and sometimes ragged and bare.
The detention that we met with in opening the road, and perhaps a willingness to linger on the way, made the afternoon's travel short; and about two miles from the entrance, we passed through another gate, and encamped on the stream at the junction of a little fork from the southward, around which the mountains stooped more gently down, forming a small open cove.
