  • Rocks of Famous Monuments Guillermo Rocha,

    Mount Rushmore National Memorial is located along the northeast edge of what is known as the Harney Peak Granite Batholith in the Black Hills of South Dakota. A batholith is a geologic feature that formed by the cooling of a large igneous body of magma below the earth's surface; if a similar igneous body reaches the earth's surface, it would form a volcanic feature such as a lava flow.

    If these rocks are buried, heated and highly compressed they will be made into metamorphic rocks. If these rocks continue to be heated and compressed to the point that they melt, then the molten rock might eventually form another igneous rock. This is called the rock cycle. It forms a complete circle as one rock can be turned into another.
