There is a “box” canyon on some private property on th eborder there near Ruidoso, Texas that has a huge open face cave (if that) you can hike up and into, to view similar pictograms...
I recall many trips to that area with my Dad, between Christmas and New Years...
Texas certainly Haas its share of interesting off the trail stuff to go check out... You just gotta go look...
Indeed. We Americans aren't the first people to have called this place home.
