The Adirondack Trail Improvement Society was founded in 1897 to insure regular maintenance and consistent marking of the trails in the St. Huberts and Ausable Lakes area. Later, the organization began hiring trail counselors to lead hiking and camping trips, thus expanding its mission to include education on the proper use and enjoyment of the Adirondack wilderness.
