Diamonds Solstice Pictographs can be found in the Wonderland of Rocks area of Joshua Tree National Park. Start at Barker Dam trailhead.
Diamond Solstice Pictograph is believed to be a summer solstice marker. The diamond patterns represent the birth canal symbolizing birth. The site is under an overhang up off the valley floor on the north-eastern side of a massive granite outcropping in the Wonderland of Rocks.
