The place today: Missouri River near White River

voyage early, and passed a creek on the south side and black
bluffs on the north. Passed White river on the south side;
one of the men and myself went up it to examine the country,
and encamped about 12 miles from the mouth, where it is
150 yards broad. We found good bottoms on this creek;
but timber scarce, and none upon the hills. The current and
colour of the water are much like those of the Missouri.
