Geology

 · The Rocks. Metamorphosed sedimentary rocks are the dominant rock types in the park, but some igneous rocks also occur. Sedimentary rocks form through a cycle of erosion and deposition mostly in water. The eroded materials include cobbles, pebbles, sand, silt, and clay, or the accumulations of shells from ancient sea animals.
