[37] Lewis and Clark did not pass within hundreds of miles of Independence Rock, having ascended the Missouri to its source. Independence Rock is a well-known landmark on the Oregon Trail—an isolated mass covering twenty-seven acres, and towering 155 feet above Sweetwater River. On it were marked the names of travelers, so that it became the "register of the desert." Frémont in 1843 says, "Many a name famous in the history of this country, and some well known to science are to be found mixed with those of the traders and of travelers for pleasure and curiosity, and of missionaries to the savages."—Ed.

[38] Captain William Sublette was born in Kentucky. His maternal grandfather was Captain Whitby, a noted pioneer of Irish ancestry. The Sublettes were also of Kentucky stock; and if French originally, came early to America. See our volume xix, p. 221, note 55 (Gregg).—Ed.

[39] This attack was attributed to the same band of Blackfeet with whom the Battle of Pierre's Hole occurred some days later. See Wyeth, Oregon Expeditions, p. 158; Irving, Rocky Mountains, i, p. 75.—Ed.

[40] This is South Pass, so named in contradistinction to the northern passes undertaken by Lewis and Clark. It is not known by whom this mountain passage was discovered, but probably by some of Ashley's parties in 1823. The ascent is so gradual that, although 7,500 feet above sea-level, its elevation is not perceived, and in 1843 Frémont could with difficulty tell just where he crossed the highest point of the divide.—Ed.

[41] The upper waters of the Colorado River are now usually termed Green River, from the "Rio Verte" of the Spaniards. This great stream rises on the western slopes of the Wind River Mountains; flowing nearly south, gathering many mountain streams, it next turns abruptly east into the northwest corner of Colorado, and having rounded the Uintah range trends to the south-southwest through Utah, until joined by Grand River, when it becomes the Colorado proper. The first attempt to navigate this formidable waterway was made by Ashley's party in 1825, although Becknell is known to have visited it the previous year. Consult Chittenden's Fur-Trade, ii, pp. 509, 778-781, and F. S. Dellenbaugh, Romance of the Colorado River (New York, 1902).—Ed.

[42] From Green River the caravan crossed the divide between the Colorado and Columbia systems, and came upon a branch of Lewis (or Snake) River, probably Hoback's River. They did not reach the main Lewis until July 6, arriving at the rendezvous on the morning of July 8, after crossing Teton Pass. Consult Wyeth, Oregon Expeditions, pp. 158, 159.—Ed.

[43] More was killed by Indians; see post. Captain Wyeth found his powder flask at Fort Union upon his return in the summer of 1833. Burdett went on to Oregon, where he resided for some years.—Ed.

[44] Pierre's Hole, known more recently as Teton Basin, is a grassy valley trending northwest and southeast, thirty miles long, and from five to fifteen wide, in eastern Idaho, just across the Wyoming border. Pierre (or Teton) River flows through it gathering affluents on the way. The valley was a well-known rendezvous, taking its name from Pierre, an Iroquois employé of the Hudson's Bay Company, who was here murdered by the Blackfeet. The Astorian overland expedition passed through this valley both going and returning (1811, 1812). The most notable event in its history was the battle which Wyeth recounts. It was not on the regular Oregon trail; see Townsend's Narrative, post.—Ed.

[45] For the Flatheads, see Franchère's Narrative, in our volume vi, p. 340, note 145.—Ed.

[46] According to Nathaniel Wyeth's journal, it was July 8 before his party arrived in Pierre's Hole. They found that Drips, the American Fur Company agent, had, with many independent trappers, reached there before them.—Ed.
