The J.D. Woodruff Cabin Site is the location of the first European-American settlement in the Big Horn Basin of Wyoming. John Dwight Woodruff built a cabin on Owl Creek in Hot Springs County in 1871. Woodruff had befriended Chief Washakie of the Shoshone people and gained Washakie's permission to graze six thousand sheep in the area, one of the first large sheep operations in Wyoming. He ran cattle in the area during the 1880s. (Ref: https://en.wikipedia.org/wiki/Woodruff_Cabin_Site)
