Leave No Trace is a nationwide low impact outdoor ethics program of the four federal land managing agencies. Leave No Trace Incorporated is a nonprofit organization that supports these efforts, and the National Outdoor Leadership School (NOLS) in Lander, Wyoming, provides agency training.

At Acadia, we are including the Leave No Trace principles in our signs, brochures, and other programs. Four ridgerunners hired by Friends of Acadia have spent each summer of 1998 educating park hikers about Leave No Trace principles and doing trail maintenance, especially maintaining cairns.

In 2001, with partners from around the State of Maine, we produced a video entitled Leave No Trace in Maine that was distributed to many state organizations for free.
