Throughout the Corps more than 4,000-mile journey, Captains Lewis and Clark recorded 178 plants and 122 animals not previously known to science. Lewis recorded and pressed and preserved some 240 different plant species and brought them back to Washington, along with hundreds of animal and bird skins and skeletons.
The Nez Perce territory at the time of Lewis and Clark (1804-1806) was approximately 17,000,000 acres (69,000 km 2). It covered parts of present-day Washington, Oregon, Montana, and Idaho, in an area surrounding the Snake, Salmon and the Clearwater rivers.
