The place today: Yellowstone-Missouri confluence
and went on at a good rate. This forenoon we passed some
of the highest bluffs I had ever seen, and on the top of the
highest we saw some Mountain sheep, which the natives say
are common about the Rocky mountains. These were the
first we had seen and we attempted to kill some of them but
did not succeed. Captain Lewis, and one of the men, trav-
elled some distance by land and killed a white bear.— The
natives call them white, but they are more of a brown grey.
They are longer than the common black bear, and have much
larger feet and talons. We went 25 miles and encamped on
the bank of a small river, which comes in on the North side
about 70 yards wide.
