Geology defined: a science that deals with the history of the earth and its life especially as recorded in rocks.
The Forest Service geology program has a key role in helping the agency to effectively achieve its mission of "Caring for the Land and Serving People." This role is to provide a basic scientific understanding of the earth--the "Land"--in particular the materials of which it is made and the geologic processes which have occurred and are in action today. This information is needed for ecologically based planning and for implementing a wide range of Forest Service land and resource management activities.
