List of Resources and Links

See the sections of resource links below for those of you interested in earth sciences. The listing has a Pacific Northwest focus, but includes resources located in adjacent states and the Rocky Mountains. Many of these links lead to even richer collections. With the exception of Rock, Gem and Mineral Clubs, most of the links are pointed to citizen scientists, students and research scientists.

Geological Society of the Oregon Country (GSOC; Portland, OR). Largest earth-science group in Oregon; monthly programs and yearly field trips, some into Washington.

Ice Age Floods Institute (IAFI; Puget Lobe Chapter, Edmonds, WA). State-wide volunteer organization focused on the ice-age floods in Washington (11 chapters in WA, ID MT, OR) .

Northwest Paleontological Association (Univ. of Washington, Seattle, WA).  Vocational and professional group that explores and preserves the paleontological heritage of Washington and the Pacific Northwest; affiliated with the Burke Museum in Seattle.  These folks go out of state for some projects, and there are quite a lot of members. It’s tough to find a place to dig – most places have been pre-ruined by unethical collectors.

Geologic map of Washington state. J. Eric Schuster, 2005; Washington Division of Geology and Earth Resources Geologic Map GM-53, 1 sheet, scale 1:500,000, with 44 p. text. We add this reference because it has a helpful pamphlet (expanded lexicon) that discusses the formations on the map and correlations thereof. The obvious limitation is the scale and thus selected map units.

Marli Miller, geologist/photographer (University of Oregon; Eugene, Oregon). Her site offers a compilation of free geology photos for instructors based on 35 years of geological field research.

Nick Zentner, geologist (Central Washington University, Ellensburg, Washington). Nick lectures (in person and on line) about all things geologic.
