Geology of the Northern Part of the Southeast Three Sisters
AN ABSTRACT OF THE THESIS OF Karl C. Wozniak for the degree of Master of Science the Department cf Geology presented on February 8, 1982 Title: Geology of the Northern Part of the Southeast Three Sisters Quadrangle, Oregon Redacted for Privacy Abstract approved: E. M. Taylorc--_, The northern part of the Southeast Three Sisters quadrangle strad- dles the crest of the central High Cascades of Oregon. The area is covered by Pleistocene and Holocene volcanic and volcaniclastic rocks that were extruded from a number of composite cones, shield volcanoes, and cinder cones. The principal eruptive centers include Sphinx Butte, The Wife, The Husband, and South Sister volcanoes. Sphinx Butte, The Wife, and The Husband are typical High Cascade shield and composite vol- canoes whose compositions are limited to basalt and basaltic andesite. South Sister is a complex composite volcano composed of a diverse assem- blage of rocks. In contrast with earlier studies, the present investi- gation finds that South Sister is not a simple accumulation of andesite and dacite lavas; nor does the eruptive sequence display obvious evolu- tionary trends or late stage divergence to basalt and rhyolite. Rather, the field relations indicate that magmas of diverse composition have been extruded from South Sister vents throughout the lifespan of this volcano. The compositional variation at South Sister is. atypical of the Oregon High Cascade platform. This variation, however, represents part of a continued pattern of late Pliocene and Pleistocene magmatic diver- sity in a local region that includes Middle Sister, South Sister, and Broken Top volcanoes. Regional and local geologic constraints combined with chemical and petrographic criteria indicate that a local subcrustal process probably produced the magmas extruded fromSouth Sister, whereas a regional subcrustal process probably producedthe magmas extruded from Sphinx Butte, The Wife, and The Husband. -

Subsistence Variability in the Willamette Valley Redacted for Privacy
AN ABSTRACT OF THE THESIS OF Francine M. Havercroft for the degree of Master of Arts in Interdisciplinary Studies in Anthropology, History and Anthropology presented on June 16, 1986. Title: Subsistence Variability in the Willamette Valley Redacted for Privacy Abstract approved: V Richard E. Ross During the summer of 1981, Oregon State University archaeologically tested three prehistoric sites on the William L. Finley National Wildlife Refuge. Among the sites tested were typical Willamette Valley floodplain and adjacent upland sites. Most settlement-subsistence pattern models proposed for the Willamette Valley have been generated with data from the eastern valley floor, western Cascade Range foothills. The work at Wm. L. Finley National Wildlife Refuge provides one of the first opportunities to view similar settings along the western margins of the Willamette Valley.
