This is the where the ore was crushed. The crushed ore then filtered into a pool of mercury in the sections nearest the camera. Operators (teenage boys) would stir the mercury mixture until the foreman deemed it the right color, whereupon the stamp on the section would be halted and the mixture taken to be purified.

Bodie had at least nine stamp mills, pounding away day and night six days of the week, with a rest on Sunday. On Sunday, Bodie babies could not sleep because it was so unusually quiet.

This is a great shot of a stamp mill, but the room is pretty dark and requires more than ISO 3200.
