Note 251 — NARRATIVE OF A YEAR'S RESIDENCE AMONG THE INDIAN TRIBES OF THE ROCKY MOUNTAINS

The route usually taken by the Indians did not follow the main branch of the river, but crossed the divide between the Missoula and Jocko rivers, coming down into the valley of the Flathead, and proceeding along that to its outlet into Clark's Fork. The two streams named for the saints were the main Flathead and Jocko rivers, which unite in the prairie described by De Smet. There were a number of small prairies in the vicinity, known as Camas from the abundance of that root (Camas esculenta). The better-known Camas Prairie was twenty miles below the mouth of the Jocko; the one mentioned by De Smet was apparently higher up, near the divide of the two rivers. These should all be distinguished from the Camas Prairie (Quamash Flats) of Lewis and Clark, which lay west of the Bitterroot Mountains.—Ed.
