Camp Awosting was founded in 1900 by Dr. Walter Truslow, member of the Kings County Medical Society of Brooklyn, New York, and Blake Hillyer, president of the executive committee of the Physical Education Society of New York. Originally established in what is now Minnewaska State Park, in Kerhonkson, NY, the camp provided boys from affluent urban communities the opportunity to "rough it" in the rugged, natural landscape of the Shawangunk Mountain range.
