(7) Jedediah Smith, letter to William Clark (11th October, 1827)
About the 22nd of August, 1826, I left the Great Salt Lake, accompanied with a party of fifteen men, for the purpose of exploring the country to the south west, which was then entirely unknown to me, and of which I could obtain no satisfactory information, from the Indians who inhabit the country on its north east borders. My general course on leaving the Lake, was S.W. and W., passing the Little Uta Lake, and ascending Ashley's River, which empties into it, where we found a nation of Indians, calling themselves Sumpatch, who were friendly disposed towards us.
After leaving the Little Uta Lake, I found no further sign of Buffalo - there were, however, a few of the Antelope and Mountain Sheep, and an abundance of Black Tailed Hares. Leaving Ashley's River, I passed over a range of mountains, S.E. and N.W., and struck a river, running SW, which I named Adams River, in compliment to our President. The water of the river is of a muddy cast, and somewhat brackish. The country is mountainous to the east, and on the west are detached rocky hills and sandy plains. Passing down this river some distance, I fell in with a nation of Indians, calling themselves Pa Utches. These Indians, as well as the Sumpatch, wear robes made of rabbet skins; they raise corn and pumpkins, on which they principally subsist - except a few hares, very little game of any description is to be found.
15th November, 1806: Saturday. Marched early. Passed two deep creeks and many high points of the rocks; also, large herds of buffalo. At two o'clock in the afternoon I thought I could distinguish a mountain to our right, which appeared like a small blue cloud; viewed it with the spy glass, and was still more confirmed in my conjecture, yet only communicated it to doctor Robinson, who was in front with me, but in halt an hour, they appeared in full view before us. When our small party arrived on the hill they with one accord gave three cheers to the Mexican mountains. Their appearance can easily be imagined by those who have crossed the Alleghany; but their sides were whiter as if covered with snow, or a white stone. Those were a spur of the grand western chain of mountains, which divide the waters of the Pacific from those of the Atlantic oceans. Before evening we discovered a fork on the south side bearing S. 25° W. and as the Spanish troops appear to have borne up it, we encamped on its banks, about one mile from its confluence, that we might make further discoveries on the morrow. Killed three buffalo.
