This collection represents a sample of faculty work from the Department of Geology. All members of the Geology faculty are actively engaged in research that involves their students. Their research interests span a broad range of topics including the environmental geochemistry of water and sediment from local water bodies, the glacial history of the Puget Sound area, paleomagnetic studies of variations in the earth's magnetic field and past plate motions, the igneous and structural history of the Olympic Peninsula, stable isotope studies of past and present food webs, and the magmatic and tectonic evolution of the Pacific Northwest.
