Nature photographer Bill Price has name this “Pluto’s Rock.” A “pluton” is a rock that formed underneath the Earth’s surface as magma slowly cooled into a solid. The term originated from Pluto, who was the Roman god of the underworld. Forty Acre Rock is an example of a pluton. This upwelling of magma results from intense heat and pressure during continental collisions that occurred some three hundred million years ago in this area. These rock features were well underneath the ground after immediate formation, but over time the process of erosion has revealed these rocks, and nature has found a way to live and in fact depend upon them.
