Hidden Gems

Rocks and minerals form the ground beneath your feet, the mountains that tower above you, and the canyons that stretch across the land. There are thousands of different minerals and three different types of rock formations: igneous, sedimentary, and metamorphic. Studying rocks and minerals can tell us about the history of the land and the animals that lived there. Find out more about the rocks and minerals in national parks and what they tell us about park stories.
