I’ve never heard of that place and I just looked it up.
It sort of reminds me of the petroglyphs at Ice Box Canyon outside of Las Vegas.

Back when I went there with a Navy contract sponsor I had who worked there, they didn’t have any organized tours and such. We pretty much went through it and had the run of the place. To me it’s just one of those visual memories I have where I didn’t have a camera and stuff.....
