"Hollow Rock" Pictographs
Back in 2010, we came across an unassuming large granite boulder in the Wonderland of Rocks of Joshua Tree. There is no shortage of granite boulders in Joshua Tree and there wasn’t anything immediately particularly interesting about this one either. But we did notice a hollowed-out cave underneath it and there was a way to crawl in. Being the exploring types, we did. To my surprise, the ceiling had a few red pictographs.
This is a well-known pictograph site now. Please respect it.
