American Heritage Girls and the Lewis and Clark Trail Heritage Foundation (LCTHF) signed a Memorandum of Understanding in August 2011. Through this MOU, the LCTHF and AHG will collaborate on projects and programs that interpret the stories of the Lewis and Clark Expedition and provide stewardship of the Lewis and Clark National Historic Trail. The Lewis and Clark Trail Heritage Foundation seeks to connect people and place in the spirit of Lewis and Clark, promote scholarship on Lewis and Clark issues, and preserve the Lewis and Clark Trail. With a national scope, the Foundation has a presence in all 50 states as well as many countries throughout the world. AHG girl members across the country are able to complete requirements to earn patches through the Ohio River Chapter of the LCTHF.
