Lewis and Clark National Historic Trail has completed a Foundation Document. This document is a formal statement of the Trail's core mission that will provide basic guidance for all planning and management decisions.

The Foundation Document reflects the congressionally established purpose of the trail, reasons why trail resources and values are significant enough to warrant national trail designation, primary interpretive themes to be conveyed to visitors, any special mandates Congress may have placed on the trail, and more general mandates contained in the large body of laws and policies that apply to all national trail system units.
