On this day in Lewis & Clark history...

Lewis and Clark are at the Great Falls of the Ohio at Louisville, Kentucky. No known journal entries exist for this day, but Lewis is likely updating Clark on the Expedition plans.

The town at the rapids is situated at Bear-grass creek, on a high and level bank of the Ohio, about 200 poles above the commencement of the rapid descent of the water, contains about 100 buildings, is the seat of justice for Jefferson county, Kentucky.
