Mining Ruins, Morristown, Arizona
We visited the Anderson Mill on the San Domingo Wash southwest of Wickenburg. The drive out was a little bumpy and will require a 4x4 vehicle. The mill was in pretty good shape for being abandoned for 60+ years. If you venture past the mill you will find the Underwood graves and miner's homesite.
Be careful when exploring this location! There are 2 or more large hornet nests that were very aggressive to explorers who walked near the top of the structure. A group of people who arrived just before me were stung multiple times while walking towards the top of the mill.
The Anderson Mill was run by two brothers. At the start of World War II all of the mines and mills that were not essential to the war effort were ordered closed. The mill was for obtaining muscovite mica. As part of the mining of the granite pegmatites other minerals were at times selectively hand cobbed and shipped. The mica produced was used as electrical and heat insulation as well as in joint compound and paint. The mill stopped operation in 1951.
