DescriptionYogoDryWashing1899.jpg | Washing the sapphire ore by hand, at the English Mine at Yogo mines, Yogo Gulch, Montana, USA. The English Mine was a meandering structure of wooden trestles, tramways, flumes and sluices. High-pressure water jets eroded away weathered sections of rock and clay. The resulting magma, or mud, passed through a series of sluice boxes. In this photograph, miners work the sluices. | |||
