A personal guided tour by owner Brantley Baird and his ranchhand, Clem Rogers, on a portion of the former Hashknife Ranch, which at one time was one of the largest in the US. Included are a museum of ranch life, a Navajo hogan and sheep pen, a prehistoric map of the region carved on a flat stone, and thousands of petroglyphs carved on the walls of a hidden canyon filled with water, wildlife and vegetation in the midst of the Arizona high desert.
