The place today: Jefferson River ascending toward divide
rise, proceeded 4 or 5 miles and crossed the river. In the
middle of the day it was very warm in the valley, and at night
very cold; so much so that two blankets were scarce a sufh-
cient covering. On each side of the valley there is a high
range of mountains, which runs nearly parallel, with some
spots of snow on their tops. We killed a deer; went about
24 miles and encamped on the south side.
