Lewis and Clark National Historic Trail Extension Study

Midwest Regional Office » Lewis and Clark National Historic Trail Extension Study » Document List

Dear Friends of the National Park Service and the Lewis and Clark National Historic Trail,

I am writing to update you on the status of the Lewis and Clark National Historic Trail Extension Study, also known as the Eastern Legacy study.

The study document was released to the public with a request for comments from individuals, groups, states, tribes, and other federal agencies from August 15 - September 30, 2016. Correspondence from approximately 323 individuals, organizations, and agencies was received and documented. All correspondence is posted in the Responses Received on the Lewis & Clark National Historic Trail Study. The National Park Service is working to finalize the study document and transmit it to Congress.

As directed by Congress, the purpose of the study is to evaluate eastern sites and segments associated with the Lewis and Clark expedition to determine whether those sites and segments should be added to the existing trail. The National Park Service researched, mapped, and evaluated 25 trail segments and additional sites using the criteria outlined in the National Trails System Act. While preparing the draft study, the National Park Service planning team considered public comment and consulted experts on the Lewis and Clark expedition.
