On this day in Lewis & Clark history...

Lewis' crew faithfully plies their oars and camps below Cow Creek on the Missouri River. On the Yellowstone, Clark lines the canoes down rapids and waits out a passing storm. He makes 45 miles camping below the Powder River.

the currant being strong and the men anxious to get on they plyed their oars faithfully and we went at the rate of about seven miles an hour.

I observe great quantities of red Stone thrown out of this river that from the appearance of the hills at a distance on its lower Side induced me to call this red Stone river.
