Ancient Native American petroglyphs are fascinating and mysterious. Here we have an ancient petroglyph panel with images made by multiple different tribes from different eras spanning back thousands of years. It’s impossible to age them exactly but age can be approximated by weathering and patina formation. And it’s very interesting to see newer, brighter images chipped on top of older, darker images. #ancient #petroglyphs #ancienthistory #losthistory #outdoorsadventure
