Create your own Rock Formation

Watch this video on Joshua tree’s rock formations.
A rock formation that resembles a skull
This skull shape formed long ago when rain drops accumulated in tiny depressions and started to erode, or eat away, the granite. As more rock eroded, more water accumulated, leading to more erosion and over time two hollowed-out eye sockets formed and the rock began to resemble a skull.
