Rapid descent of Missouri, 70-80 miles/day — Patrick Gass: August 29, 1806
Patrick Gass · Prairie dog village near present-day Chamberlain · Thwaites Vol. Gass 1807 First Edition
The place today: Prairie dog village near present-day Chamberlain
went on ahead very early; while we amused ourselves till 10
o’clock gathering plumbs, of which there is great abundance
at this place. We then went on, and passed White river on
the south side. The Missouri here is very full of sand bars
and shoals, and we find difficulty in getting along. About
2 o’clock we halted to kill some buffaloe, but were unsuccess-
ful, and we proceeded, till evening, and encamped.
