The White River Bridge on Oregon Route 35, east of Mount Hood, after the debris flow events of early November 2006. Note the blue-jacketed person standing in the channel near the center of the bridge span. The debris deposit is roughly 12-18 ft high on the upslope side of the bridge. Debris completely filled the channel and overtopped the bridge deck. Route 35 was re-opened December 9, 2006.

Recently Published: Oregon Geologic Data Compilation (OGDC-3) contains the Southeast and Northeast Oregon Geologic Compilation data sets plus the newly added Central Oregon data set, including the High Cascades -– Mt. Bachelor, the Three Sisters, the Cascade Lakes region -– and Newberry National Volcanic Monument. OGDC-3 also includes Bend, Redmond, Prineville and the John Day Fossil Beds National Monument.

The purpose of the Oregon Geologic Data Compilation 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 data set. 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 information becomes available. Knowledge of and access to GIS and database software applications are essential to the use of the CD version of the compilation.

Oregon Geologic Data Compilation -- Version 3 (OGDC-3) is available on CD-ROM for $25. It can be purchased from the Nature of the Northwest Information Center (NNW), 800 NE Oregon Street, Suite 177, Portland, Oregon, 97232. You may also call NNW at (503) 872-2750 or order online at http://www.naturenw.org. There is a $3 shipping and handling charge for all mailed items.
