They skirt a white‐barked aspen grove and cross marshy Big Meadow, sharing the grasses with horses and livestock, on a nature trail with viewing areas for dozens of colorful species of birds. This is summer at the 1,830‐acre Black Butte Ranch. The nearest Central Oregon resort to the Willamette Valley, just 100 miles east of Eugene via Santiam Pass, the 45‐year‐old destination property delivers on a promise of relaxation. Families may enjoy summer visits when swimming pools are open and other activities, including golf, tennis and horseback riding, are going full bore, but Black Butte Ranch, known as BBR, thrives on serenity. Other resorts are all about hustle and bustle, but Black Butte even banishes overhead street lights, enhancing a “night sky” program that makes the heavens come alive.

  • Overview for Geologic Field-Trip Guides to Mount Mazama, Crater Lake Caldera, and Newberry Volcano, Oregon
    Overview for Geologic Field-Trip Guides to Mount Mazama, Crater Lake Caldera, and Newberry Volcano, Oregon Scientific Investigations Report 2017–5022–J U.S. Department of the Interior U.S. Geological Survey Cover (top photo): View east-northeast from Garfield Peak on the south rim of Crater Lake caldera. Peak on skyline is 8,929 feet (2,722 meters) Mount Scott, an ~420 thousand years before present (ka) dacite stratovolcano considered to be part of Mount Mazama, the volcano that collapsed during the caldera-forming eruption ~7,700 years ago. The caldera walls in this view expose Mazama lava flows and fragmental deposits from as old as ~400 ka at Phantom Cone, adjacent to tiny Phantom Ship island, to as young as ~27 ka at Redcloud Cliff, the V-shaped face at the top of the wall left of center. The beheaded glacial valley of Kerr Notch, the low point on the caldera rim, is seen between Phantom Ship and Mount Scott. Photograph by Carly McLanahan. Cover (bottom photo): Newberry Volcano, Oregon, is the largest volcano in the Cascades volcanic arc. This north-facing view taken from the volcano’s peak, Paulina Peak (elevation 7,984 feet), encompasses much of the volcano’s 4-by-5-milewide central caldera, a volcanic depression formed in a powerful explosive eruption about 75,000 years ago. The caldera’s two lakes, Paulina Lake (left) and the slightly higher East Lake (right), are fed in part by active hot springs heated by molten rock (magma) deep beneath the caldera. The Central Pumice Cone sits between the lakes.

  • 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.

  • And Post-Laramide Geology of the South-Central
    Syn- and post-Laramide geology of the south-central Gravelly Range, southwestern Montana by Ernest Jan Luikart A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Earth Sciences Montana State University © Copyright by Ernest Jan Luikart (1997) Abstract: The geologic history of post-Laramide basin evolution in the foreland of southwestern Montana has been a matter of controversy. A complex assemblage of Upper Cretaceous to Tertiary sedimentary and volcanic rocks which record some of that history are exposed on and near the crest of the Gravelly Range. Past interpretations of their relations and tectonic implications conflict. The present investigation of a portion of the southern Gravelly Range crest helps to resolve the physical stratigraphy and ages of the post-Laramide deposits and suggests the following sequence of events: (1) syn- and post-Laramide erosional beveling of the Madison-Gravelly arch; (2) Late Cretaceous deposition of quartzite gravel from a thrust belt source, locally containing Archean metamorphic clasts from a foreland source; (3) conformable transition to deposition of limestone conglomerate derived from the Blacktail-Snowcrest arch, with interbedded siltstone, sandstone and lacustrine limestone, deposited prior to the end of Laramide deformation; (4) final movement of Laramide faults; (5) erosion represented by a 28-38 my-long unconformity; (6) deposition of tuffaceous mudstones beginning in the Duchesnean (40-37 Ma) and proceeding into the Whitneyan (32-29 Ma) interrupted by erosion at about 32 Ma; (7) eruption of basalt flows from local vents between 33 and 30 Ma; (8) minor erosion followed by early Miocene (23 Ma) eruption of an isolated mafic volcanic center; (9) emplacement of Huckleberry Ridge Tuff at 2.1 Ma after erosion or nondeposition of Miocene strata; (10) significant uplift of the range in Quaternary time; (11) Pleistocene deposition of glacial moraines in the deeper valleys, and ongoing mass-movement and colluvial processes.

Perkins, Chair Michael Cummings Kenneth Lite, Jr. Portland State University ©2011 Abstract McKinney Butte, a late Tertiary andesite vent and flow complex, is located near the town of Sisters, Oregon, in the upper Deschutes Basin, and is situated along the structural trend that forms the eastern margin of the High Cascades graben (Sisters fault zone and Green Ridge). Rapid development and over appropriated surface water resources in this area have led to an increased dependence upon groundwater resources. A primary concern of resource managers is the potential impact of expanding groundwater use on stream flows and spring discharge. Two sets of springs (McKinney Butte Springs and Camp Polk Springs) discharge to Whychus Creek along the east flank of McKinney Butte, and during low-flow conditions supply a substantial component of the total flow in the creek.
