There are two pictographs sites in Indian Wells Canyon, this one and the “Mandala” one. In terms of elements present, this is the smaller of the two.
A quick word on Indian Wells Canyon: although the lower portions of the canyon are accessible by a rather fine dirt road, that road deteriorates quickly as you ascend the canyon. Some bumpy, overgrown sections are best NOT attempted in passenger vehicles. Additionally, the higher reaches are braided by several roads and picking the wrong one will quickly lead you into bad driving conditions.
