Pit crew working in the Gold Pan Mining Company's excavation pit, south of Breckenridge, Colorado. Circa 1900s. Standing in knee deep water, men use shovels to heave boulders larger than 8 inches into the "stone boat", a rectangular metal platform edged on three sides. The attached cable pulled the boat up to the surface, where it dumped the rocks on the west side. The large pipes are part of the Evans hydraulic elevator system.
