You can see the symbol for the Frank Lloyd Wright Foundation is the second petroglyph from the left.
Petroglyphs are rock art made by removing part of the rock's surface by carving or incising the rock to create the art.
Petroglyphs are thousands of years old. We have a lot of petroglyphs in Arizona and the surrounding Southwest.
