On this day in Lewis & Clark history...

Lewis dispatches the keelboat and crew from Cincinnati, Ohio with instructions to meet him at Big Bone Lick. Lewis will travel by land and investigate the mammoth fossils being excavated by Dr. William Goforth.

From the journals...

Dear Sir [President Jefferson],
On the evening of the 1st inst. I again dispatched my boat with orders to meet me at the Big Bone lick, to which place I shall pass by land, it being distant from hence only seventeen miles while by water it is fifty three, a distance that will require my boat in the present state of the water near three days to attain.1
