Stamp Mill

Tonopah Mining Museum, Nevada. A 19th century device for crushing ore--a belt turned the big pulley, which in turn spun a camshaft that lifted and dropped the stamps. Altho stamp mills lingered into the 20th century at small undercapitalized mines, they were obsolete even by Tonopah's heyday after the turn of the last century. I think, therefore, this mill was brought in for the museum and was never used locally.
