Forces of Columbia River displayed on new map poster

The raw earth exposed by the path of the Columbia River offers a look at the power of natural systems, and a new poster-quality map issued by Washington and Oregon geologists shows where you can see those natural forces.

“Washington and Oregon are privileged to share in the stewardship of one of the world’s most remarkable river systems: the Columbia River, a geologic and cultural treasure that has shaped the destinies of our two states,” says David Norman, Washington State Geologist.

The Washington State Department of Natural Resource’s Geology and Earth Resources Division, in cooperation with the Oregon Department of Geology and Mineral Industries, has produced a map to highlight the geologic influences that converge along the river in recognition of Geologic Map Day October 17. The map highlights the geology of the 309-mile stretch of the river that divides the two states and presents hazards like floods and benefits like how winds and water are captured to produce electricity.

The map poster is available for download as a 34-by-44-inch PDF or as eight 11-by-17-inch PDFs for easy assembly: http://bit.ly/mapday2014

In other activities recognizing Geologic Map Day, the Washington Geology Library will have geologic maps on display and some geologically-themed baked goods from 8 a.m. to 4 p.m. in the Washington Geology Library, Room 173, Natural Resources Building, 1111 Washington St SE, Olympia, WA.

The Washington Geology Library holds more than 3,000 topographic and geologic maps of Washington, in addition to volumes of research on our state’s unique geology.
