The place today: Lolo Trail, ascending into Bitterroot Mountains
continued our journey down the river. The soil of the valley
is poor and gravelly; and the high snow-topped mountains
are still in view on our left; Our course generally north a few
degrees west. We halted at noon: on our way the hunters
had killed 3 wild geese; so we have plenty of provisions at
present. At 2 o’clock we again went forward, and crossed
over the Flathead river, about 100 yards wide, and which we
called Clarke’s river; passed through a close timbered bot-
tom of about two miles, and again came into beautiful plains.
