Heading north toward Face Rock area. I can see both the Face Rock and Elephant Face Rock which I have tagged.

Granites crystallize at a depth of several miles into the crust. As erosion removes the several miles thick pile of rocks above the granite, the pressure acting over it decreases and the granite body starts to fracture. In Joshua Tree there are at least three dominant sets of fractures, one roughly horizontal and other two varying from vertical to steeply inclined, separating the granite into a series of rectangular blocks.
