The Story

The Untold Chapter of Lewis and Clark

Most people know about the 1804–1806 Corps of Discovery. Far fewer know that in 1809, Meriwether Lewis traveled from the Ohio River at Paducah down to Fort Pickering — present-day Memphis — on his final journey east. That stretch of river has never been comprehensively documented. Until now.

The Lewis and Clark Trust is leading a 360° documentation effort covering every mile from Paducah, KY to south of Memphis, TN — extending the existing Lewis and Clark National Historic Trail digital map seamlessly into the Lower Mississippi.

Lewis in 1809

Memphis on the Mississippi

Three years after the triumphant return of the Corps of Discovery, Meriwether Lewis was Governor of Upper Louisiana and under intense political pressure. In late summer 1809 he set out from St. Louis bound for Washington, D.C. to defend his administration of the territory and to publish the journals of the expedition. The chosen route ran down the Mississippi to the Chickasaw Bluffs, where Fort Pickering — modern-day Memphis — stood as the last federal outpost before the journey turned overland through the Natchez Trace.

Lewis arrived at Fort Pickering on September 15, 1809, exhausted and ill. He stayed two weeks under the care of Captain Gilbert C. Russell, recovering enough to continue. He set out again at the start of October, accompanied by his servant John Pernier, the Chickasaw agent James Neelly, and Neelly’s slave. The party crossed the Tennessee River and entered the Trace.

On the night of October 11, 1809, at Grinder’s Stand in middle Tennessee, Lewis died. The circumstances remain debated to this day — most scholars accept suicide; a vocal minority continue to argue murder. What is undisputed is that Lewis’s last great river journey followed the Lower Mississippi, and that no comprehensive visual record of that route exists.

This campaign closes that gap. Following the same corridor Lewis traveled in 1809, the Trust will document every mile from Paducah down past Memphis, building a free public archive that extends the Lewis and Clark National Historic Trail digital map into the Lower Mississippi for the first time.
