Site of Rowland, Nevada, near the Bruneau Mine. This was a minor gold-silver producer in the early 20th century. The construction is surprisingly archaic, with finished boards for the sides but merely trimmed timbers for the supporting posts.

Golden Gate stamp mill, showing one of the hoppers where the stamps stamped. The manufacturer's label reads, "Joshua Hendy Iron Works S.F. Cal." Yes, in the early 20th century there was heavy industry in San Francisco!
