The place today: Missouri River near Cheyenne River
clear day; passed bluffs on the south side and a bottom cov-
ered with timber on the north. About 11 we passed a hand-
some bottom, where a band of the Rees lived last winter.
They had left a number of round huts covered with earth,
some of their water craft made of buffaloe hides, and some
garden truck, such as squashes. We proceeded on and passed
a small creek on the south side; a handsome bottom on the
north; and encamped on a sand beach on the north side.
