America’s Geologic Legacy

Come and explore the world's most magnificent rock collection—your National Parks. The science of geology will help you to better understand park scenery and Earth systems. The National Park Service uses science-based conservation methods to ensure that geologic features and systems are protected and remain as a legacy for future generations. But, our treasured geologic sites need everyone’s help and respect—most have developed through natural processes over millions of years and are irreplaceable. Learn about geology, visit the parks, and discover your Geologic Heritage.
