The first panel, which is (unusually) on the east wall of the canyon. Note the centipede-like figure with lines beneath it (which probably represents a cloudburst, not an arthropod). Also the pregnant female figure at lower right. As Ranger Jim correctly points out, you are free to see what you want to see in these depictions - no one alive can disprove your interpretation. Jim sees the panels as a form of storytelling. Works for me!
