Mapping the Lewis & Clark National Historic Trail
The National Park Service and the Lewis and Clark National Historic Trail is working to virtually map the rivers that the Expedition followed in their search for an all water route between the Atlantic Ocean and the Pacific Ocean. The Trail follows some of the United State's main water arteries, including the entirety, sections, or tributaries of the Ohio River, Mississippi River, Missouri River, Snake River, Blackfoot River and Columbia River.
High-resolution imagery captured from a one-of-a-kind river raft allows voyagers to witness - from any corner of the world - the White Cliffs and Gates of the Mountains along the mighty Missouri River, the Heart of the Monster on the Nez Perce Reservation, and the quiet stillness of the Snake River in southeast Washington. In mapping the Lewis and Clark National Historic Trail, The National Park Service brings forth its missions to support citizen sciences all while stewarding a Trail that advocates accessibility for all.
