    What secrets lie within Olympic National Park’s forests, lakes, and skies? From tracking bats to uncovering ancient earthquakes, USGS scientists are working with the National Park Service to reveal how Olympic’s natural systems change, connect, and respond to emerging

    Every national park has a story written in rock, water, and wildlife. USGS scientists are helping tell it. Across many parks, USGS scientists study changing ecosystems, wildlife, water, and natural hazards. From tracking contaminants in aquatic food webs to monitoring glaciers,

    Your phone started as rocks. So did your laptop, your car battery, and the jumbotron displaying your favorite team’s score. Before any of that technology existed, the raw materials inside it (minerals!) had to be found and understood. Minerals are naturally occurring
