The Lewis and Clark National Historic Trail, a trail of approximately three thousand seven hundred miles, extending from Wood River, Illinois, to the mouth of the Columbia River in Oregon, following the outbound and inbound routes of the Lewis and Clark Expedition was created by Congress in the National Scenic and National Historic Trails law (16 U.S.C. 1244(a)). Today's Lewis and Clark NHT is the joint effort of many organizations and agencies. Although the Trail is administered by the NPS, sites along the Trail are managed by federal land management agencies, state, local, tribal, and private organizations.
