This was an extremely interesting site even tough we are not sure if it is old, historic, or a mixture of both. A few nearby rock rings appear to be very old, but we have been told that the blinds or walls are probably more recent.
We were hiking two small hills separated by an east/west running wash and while on the south side of the wash we started finding stone blinds / walls (possibly hunting blinds). The blinds ranged from 2’ to 3’ high and 8’ to 12’ long. Vertically they were about 20’ to 30’ above the wash and horizontality they were 100’ to 200’ from the wash bottom.
While we were investigating the blinds on the south side of the wash, we noticed more blinds on the north side of the wash at about the same level. After getting to the north side of the wash, we spotted the lower blinds and several more higher up on the hill. Because of the distance to the wash / trail below this is looking more like an ambush site that would be used with rifles or handguns vs. bows and arrows.
Near the blinds on the north hill we found a rifle cartridge that was necked down twice (probably a blank) and an old ammo box. At the top of the hill we found an aluminum spike imprinted with “FORT ARIOTTI” and a surveyor number RLS 2878. When my hiking partner put this information on his Facebook page, the general consensus was that we found an old movie set or possibly a military training or reenactment area. I am still hoping for something a bit older.
