Geologic Resources

Geologic resources are natural features or areas whose unique geologic attributes provide important scientific or educational value and support multiple uses of National Forest System lands. Management of geological resources preserves their value as significant landscape elements held by the agency in the public trust. The Geologic Resources Program supports the agency’s mission of "Caring for the Land and Serving People" by contributing to a scientific understanding of the earth -- the "Land" -- in particular the materials of which it is made, the geologic processes which have occurred and are in action today and geologic history as recorded in the rocks. This information is needed for ecologically-based planning and or implementing a wide range of Forest Service land and resource management activities.


CAVES AND KARST Caves and karst resources occur in over 100 national forests in the United States. Karst is formed by the dissolution of soluble carbonate bedrock such as limestone, dolostone and marble. LEARN MORE GROUNDWATER Groundwater is a critical component of the hydrologic cycle and is important in sustaining groundwater dependent ecosystems and support biodiversity on many forests and grasslands. LEARN MORE PALEONTOLOGY The Forest Service is dedicated to protecting and managing the paleontological (fossil) resources which are important to our natural resource inheritance.
