Prospectors needed a dependable water supply for their mining camps. In Emigrant Canyon, on the west side of Death Valley in the Panamint Mountains, a reliable spring was tapped for the scattered mining camps in the northern part of the range. Use of this spring dates from the Jayhawkers, who crossed Death Valley in 1850. Despite the time-honored image of the miner and his burro, much of the transportation was by automobile over rough dirt roads. The building at left was moved to Harrisburg camp shortly after this photograph was taken. (photographer unknown, courtesy of Death Valley National Park, no number)
