17 Origin of Rock Formations at Joshua Tree Park, California

As you drive along Park Boulevard, you are impressed by the amazing rock formations. But how did these sculpted piles of boulders get here? Their origin is volcanic. Hot magma rose towards the surface. As it cooled, it cracked and crystalized into a material called monzogranite. It was further shaped by groundwater and then exposed through erosion.
