LECL Lewis and Clark Expedition Historic Tributaries and Streams
Lewis and Clark National Historic Trail. 2018. LECL Lewis and Clark Expedition Historic Tributaries and Streams. National Park Service
This dataset represents the historic tributaries and streams documented by Lewis and Clark and the Corps of Discovery along the Missouri River during the 1804-1805 outbound journey of the Lewis and Clark Expedition. These locations were determined by James D. Harlan of the University of Missouri-Columbia. The Lewis and Clark National Historic Trail is approximately 4,900 miles long, extending from the Ohio River in Pittsburgh, Pennsylvania to the mouth of the Columbia River in Oregon, following both the outbound and inbound routes of the Lewis and Clark Expedition. The trail connects 16 states (Pennsylvania, West Virginia, Ohio, Indiana, Kentucky, Illinois, Missouri, Kansas, Nebraska, Iowa, South Dakota, North Dakota, Montana, Idaho, Washington, and Oregon) and was established by Congress in 1978 as part of the national trails system (NTS) as one of four original national historic trails. This trail commemorates the 1803-1806 expedition of Lewis and Clark and the Corps of Discovery, which explored the Louisiana Territory and beyond. This epic journey contributed to significant scientific knowledge and profound political, social, economic, cultural, and environmental changes to the lands and the peoples of the North American continent.
