Mill foundation

Candelaria district, Mineral County, Nevada. This was the site of the mill for the 19th century ore-crushing operations. Only the (stone) foundation remains--presumably concrete was way too expensive at the time, with the transporation costs. All the superstructure--the timbers, the stamp mills, and so on--is also gone, presumably moved on to the next big strike. They were way too valuable to just abandon! Such mills, even into the 20th century, were build on a slope so that the ore could be moved thru the operation by gravity. The inset photo shows a different view.
