Lewis crossed the divide by the gap now known as Lewis and Clark's Pass; it
is on the boundary line between Deer Lodge and Lewis and Clarke counties, about
45 miles (in a direct line) N. N. W. from Helena. From the headwaters of Big
Blackfoot River, Lewis passed to those of Sun (Medicine) River, by which he soon
reached the Missouri—to which river he thus followed the easiest and most direct
route from the head of the Clearwater. Cf. accounts of this pass and its approaches
from either side, as given by Gass (pp. 342, 343), and by Stevens (Explor. for R.R. to
Pacific
, xii, pp. 213–215); and see Clark's description, post, in scientific data, vol.
vi of the present work.—Ed.

Fort Mountain is south of Fort Shaw, identified as Square Butte, always visible
from Lewis and Clark Pass. For the explorer's first sight of this landmark, see vol.
iii, pp. 228–231, ante.—Ed.

The "rivulets running to the wright" were affluents of Dearborn River—the
nearest route to the Missouri. Lewis, however, struck north for the upper waters of
the Medicine or Sun River, in order to secure buffalo skins for the expedition.—Ed.
