Title: Hidden Cave
Location: Joshua Tree National Park, California
This hidden location hosts some of the best and most elaborate pictographs in all of Joshua Tree National Park. This is a protected location. Park Service Rangers will likely not acknowledge it’s existence if you ask. They almost certainly will not tell you where to find it.
Rock art preservation vs. public knowledge is a serious debate these days. Joshua Tree National Park hosts a wide variety of petroglyphs, pictographs, and other rock art throughout the park. Some locations have sustained significant damage. The increased popularity of Joshua Tree has made this an even bigger issue.
I will not reveal this location to anybody who asks under any circumstances.
