Spirit Bighorn |
The rock here is a porous basalt/andesite, and the petroglyphs here were very deep, and many were also clearly very very old. Many of them were completely varnished over, detectable only by standing at the right angle with the sun glare exposing the divots where the glyph is.
Panels here were largely Coso in style, with a few bighorns and a few anthropomorphic people in the mix as well. More recent glyphs are probably from the Timbisha Shoshone, a few hundred to over a thousand years, while the oldest are likely at least 8,000 years old.
