What is it?

The Oregon Department of Geology and Mineral Industries (DOGAMI) has completed (May 2009, OGDC-5) a six-year project to digitally compile geologic data for the entire state. This effort brings together the best available geologic mapping from state and federal agency sources, student thesis work, and consultants, although viewers are cautioned that it is a work in progress.
