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.
Lewis collected a number of plant and animal specimens along the way and made scientific observations. Due to the rough terrain, the men only managed to travel about 12 to 14 miles on a good day. Lewis and Clark made it back to St. Louis on September 23, 1806. Due to how long they were gone, many feared that they died on their journey. Despite the hardships the team faced while on this expedition, only one man died on the trip.
