On this day in Lewis & Clark history...
In what appears to be his last journal entry until Nov. 11, Lewis describes a steep Ohio River rapid at present Letart Falls, Ohio.
From the journals...
The morning was clear and having had every thing in readiness the over night we set out before sunrise and at nine in the morning passed Letart's falls; this being nine miles distant from our encampment of the last evening—
this rappid is the most considerable in the whole course of the Ohio, except the rappids as they ar called opposite to Louisville in Kentuckey— the descent at Letart's falls is a little more than 4 four feet in two hundred fifty yards.
