Skull Rock is another example of human pattern recognition. Two hollows resemble eye sockets, turning ordinary granite weathering into a face.
The hollows developed where water collected and chemical weathering weakened the rock. Once exposed, wind and runoff continued to enlarge them.
The skull interpretation is culturally useful because it gives visitors an easy landmark. Geologically, however, the rock belongs to the same weathering process that produced countless rounded boulders nearby.
Ending here returns to the guide’s central theme. Desert forms become meaningful because humans name them, use them and tell stories about them. The physical processes remain indifferent. Rock weathers; people see a face.
