On this day in Lewis & Clark history...

Nez Perce men guide Lewis to the Blackfoot River where they exchange gifts and go separate ways. Clark continues up the Bitterroot River. He crosses the swift and deep river near present Connor, Montana wetting some of the cargo.

I now continued my rout up the N. side of the Cokahlahishkit river through a timbered country for 8 miles and encamped in a handsom bottom on the river where there was an abundance of excelence grass for our horses.

the banks bold not very high but never overflow.
the East fork below its junction with this stream is 100 yds. wide and above it about 90.
the water of boath are terbid but the East branch much the most so; their beds are composed of sand and gravel;
the East fork possesses a large portion of the former.
neither of those streams are navigable in consequence of the rapids and shoals which obstruct their currents.
