Gold mining stamp mills at North Star Mining Museum and Power House in Grass Valley, CA. These stamp mills were used to break up the ore to release the gold from the rock. Note the cams that made the shafts go up and then drop when they came off of the ends of the cams. The noise and vibration mus have been amazing.
