Tundra Rock Formations
"The rocks in these odd formations were born of fire and water. The dark-colored schist was originally sand, silt and clay at the bottom of a long departed sea. Molten magma from deep within the earth invaded the schist and gradually cooled into the lighter-colored granite. Mushroom shapes were formed when the granite stems eroded quicker than the schist caps." -trail sign RMNP
