Oregon Geology

For all who love Oregon and Geology, this map tool link is worthy of checking out.

The purpose of the Oregon Geologic Data Compilation <--click here to go to the site (OGDC) project is to assemble the best available geologic map information for the entire state by integrating the work of many individual geologic mappers into a vector digital dataset. The data are stored in a geographic information system (GIS) format with links to a relational database. The compilation is thus a "living map" that can change as new geologic information and mapping becomes available.

What is it?

The Oregon Department of Geology and Mineral Industries (DOGAMI) has completed (May 2009) 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.

You can view Oregon stratigraphy, rock type, and rock property theme maps on topographic and shaded relief backdrops along with faults, formation boundaries, and USGS 7.5' topographic quadrangle outlines and names. You can drag a portion of the map, and it recreates the map in a closer view. You can see fault lines, and there are pop up keys to determine geologic information.
