On this day in Lewis & Clark history...

Lewis and Clark are within one day's journey from Fort Massac. Near this date, the keelboat passes the Cumberland River.

From the journals...

This river rises in the Cumberland mountains, on the confines of Virginia, winding to a S. W. course, advances into the S. W. Territory, thence meandering in a N. W. direction, passes by Nashville, in the state of Tennessee, into Kentucky, and unites with the Ohio in a west direction; it is 300 yards wide at its mouth, and is navigable for loaded boats up to Nashville, and for smaller crafts up to the division line of Kentucky
