Southern Counterpart to Lewis and Clark: The Freeman and Custis Expedition of 1806

In 1806 President Thomas Jefferson sent cartographer Thomas Freeman and botanist Peter Custis to explore the southen Louisiana Purchase westward to the Rocky Moutnains. Stopped by a Spanish army in what is today extreme southern Oklahoma, they did not complete their mission. President Jefferson minimized their failure by focusing instead on the success of their northern counterparts Lewis and Clark. Hence the fame of Lewis and Clark and the virtual anonymity of Freeman and Custis-until now, thanks to editor Dan L. Flores.

Dan Flores presents the primary documents created by Freeman and Custis during their ill-fated attempt to explore the Louisiana territory and areas west of the Mississippi in 1806.

Dan Flores is retired as A. B. Hammond Professor of History at the University of Montana, Missoula. He is the author of numerous books, including Visions of the Big Sky: Painting and Photographing the Northern Rocky Mountain West and The Natural West: Environmental History in the Great Plains and Rocky Mountains.
