Castle Crags

This picture of the Castle Crags was taken off Interstate 5 at Castle Crags State Park near Castella, California.  The Castle Crags are made from granite that cooled slowly deep within the Earth.  Over time, this granitic pluton (igneous rock that solidified below Earth's surface) was lifted and the rock above it wore away.  Once the granite was exposed to the elements, water and ice have taken over as the main sculpting tools.  I was thinking that the Crags look a little like the back of a large dinosaur!
