Hello
Here is a photo of what I think are defense walls in the Superstition Mountains.

I am having some challenge to getting groups of photos posted but thanks to Jims help I can at least share this one.
I found this in 2009 while investigating what I believe is or was a Spanish base camp.
I found three such ruins along with a rock cairn and two rock images of horses as well as a spanish face.
These walls were stratigicaly located as to afford the best overall view of the only approch to the camp.
So far I have not read of these particular stuctures being reported by anyone.
Best Regards
Alan
