The Maah Daah Hey Trail Association is a nonprofit organization dedicated to providing and maintaining a linear, non-motorized, sustainable, recreational trail system in southwest North Dakota, through voluntary and public involvement, and in cooperation with the USDA Forest Service.

The symbol for the trail is the turtle. Adopted from the Lakota Sioux Indians, the turtle symbolizes patience, loyalty, determination, steadfastness, long-life and fortitude. The turtle shell symbolizes protection and its effigy is emblazoned on the posts that mark the trail.
