At the Presidio in San Francisco, an important coastal fortification for something like a century, and now a historical site. These emplacements date from ca. 1890s. For more on the Presidio see the enclosing photo.

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.

Only the foundations of the mill remain.

Ione, Nevada. As I've mentioned, mills for processing ore were built on a hillside, so you could dump the ore in at the top and move it thru by gravity. The fact that these foundations are concrete suggests a date around the turn of the last century. The size of the trees that have grown up, however, indicates it wasn't abandoned yesterday! ;)

Looking west out toward Washoe Valley and the Carson Range. The main town site is about half a mile upstream, to the right.

Another view of a wall in the mill foundation.

Wildhorse Canyon. Seven Troughs District, Pershing County, Nevada, USA. There were a slew of old mills in and around this area.
