The Hills Have Eyes
There's not much information on Sundad available on the internet, but it was established as a tuberculosis sanitarium in the 1920s. With TB being highly contagious, the distance from Phoenix kept healthy folks safe, while it was felt the dry, warm, air would be beneficial to the patients. The sanitarium did not last long. In more recent decades, it has been a party spot for off roaders. That is not as bad as it sounds, and is actually quite cool, as they have turned the rocks and many bottles into interesting rock art designs. (Just look at sat view!) "Sundad" is spelled out several times, and there are circles, diamonds, wheels, flowers, sunrises, arrows, and many other designs. Pretty cool!
Watch your step: Lots of nails as well.
As with many places in Arizona, it almost goes without saying, there was also mining in the area. Not sure when that started & ended, but it could be around the same time as the sanitarium as there are cement tanks next to the two shafts I found, as well as many prospects. Not sure what a cement tank would be doing up hill from a shaft? Unusual.
The entire Sundad site is about 500 yards south-to-north, and maybe 100 yards wide.
