Across this small canyon, the stone foundation and other remnants of the Barbee and Walker Mill are still visible. The Barbee and Walker Mine that provided silver ore for the mill was located in this same area. As miners brought the ore-bearing rock to the surface, this mill and others at Silver Reef were essential for refining the silver. William Tecumseh Barbee was one of the earliest people to prospect for silver in southwest Utah and made one of the most significant discoveries. His initial claims were staked in 1875, and the mine and mill were in full operation by 1878. Barbee's discoveries are credited with starting the largest rush of prospectors and miners to Silver Reef. The mill and mine were named for him and the Walker brothers of Salt Lake City who were his partners.
