Lewis and Clark National Historic Trail Extension Study

Thank you for your interest in the Lewis and Clark National Historic Trail Extension Study, also known as the Eastern Legacy Study.

The National Park Service has been directed by Congress to conduct a study to assess the suitability and feasibility of adding trail segments and/or sites associated with the preparation and return phases of the Lewis and Clark expedition to the existing Lewis and Clark National Historic Trail. The existing Trail extends west from Wood River, Illinois for approximately 3,700 miles to the mouth of the Columbia River in Oregon and Washington. The study area for the Eastern Legacy extends from Wood River, Illinois along the Mississippi and Ohio Rivers to Pittsburgh, Pennsylvania and will include additional sites and routes followed by Meriwether Lewis and William Clark, whether independently or together, prior to and following the 1804-1806 expedition.

The NPS will review and consider previous studies and public input and will then assess the suitability and feasibility of extending the Trail. As part of this study, the NPS will evaluate options for protection and interpretation of these segments and/or sites by the National Park Service in cooperation with other federal, state, local, private or non-profit partners following direction provided in the 1968 National Trails System Act (as amended).

Public input plays a critical role in this process and we invite you to participate in this study. Once the study is completed, Congress will make the final determination of what, if any, action it will take regarding an extension of the existing Trail.

The NPS expects to release the draft study for public review in Summer 2016.

Please check this website periodically for updates on the study and to view documents that are open for public review and comment. Your input is important for the success of this study. We encourage you to take part in this process and look forward to hearing from you.
