Jumbo Rock Formations

Jumbo Rocks is one of the most popular spots in Joshua Tree National Park, and it's easy to see why. These formations are the result of a complex granite geological history that dates back millions of years and were eroded by the elements into incredible shapes.

Skull Rock (featured at the end of this post) is one of the most iconic and recognizable rock formations at Jumbo Rocks in Joshua Tree National Park. The formation gets its name from its striking resemblance to a human skull, with two large eye sockets and a nasal cavity. See if you can also spot the aptly-named Penguin Rock, which is hidden away in the Jumbo Rocks Campground by a beautifully twisted juniper tree.
