The Wisconsin Range party was composed of: Gunter Faure, leader and geochronologist; John Mercer, glacial geologist; John Murtaugh, igneous petrclogist; James Teller, field assistant; Courtney Skinner, field assistant; Harry Gair, visiting strati- grapher. The author served as a stratigrapher with both expedi tions . Various members of the staff of the Department of Geology, The Ohio State University, as well as some specialists from the outside were consulted in the laboratory studies for the pre paration of this report. Dr. George E. Moore supervised the petrographic work and critically reviewed the manuscript. Dr. J. M. Schopf examined the coal and plant fossils, and provided information concerning their age and environmental significance. Drs. Richard P. Goldthwait and Colin B. B. Bull spent time with the author discussing the late Paleozoic glacial deposits, and reviewed portions of the manuscript. -
Play Fairway Analysis of the Central Cascades Arc-Backarc Regime, Oregon: Preliminary Indications

Moore1, Eric L. Sonnenthal3, Virginie Maris1, and John D. Trimble2 1University of Utah/EGI, Salt Lake City UT 2Oregon State University, College of Earth, Ocean and Atmospheric Sciences, Corvallis OR 3Lawrence Berkeley National Laboratory, Center for Isotope Geochemistry, Berkeley CA [email protected] Keywords Play Fairway Analysis, geothermal exploration, Cascades, andesitic volcanism, rift volcanism, magnetotellurics, LiDAR, geothermometry ABSTRACT We are assessing the geothermal potential including possible blind systems of the Central Cascades arc-backarc regime of central Oregon through a Play Fairway Analysis (PFA) of existing geoscientific data. A PFA working model is adopted where MT low resistivity upwellings suggesting geothermal fluids may coincide with dilatent geological structural settings and observed thermal fluids with deep high-temperature contributions. A challenge in the Central Cascades region is to make useful Play assessments in the face of sparse data coverage. Magnetotelluric (MT) data from the relatively dense EMSLAB transect combined with regional Earthscope stations have undergone 3D inversion using a new edge finite element formulation. Inversion shows that low resistivity upwellings are associated with known geothermal areas Breitenbush and Kahneeta Hot Springs in the Mount Jefferson area, as well as others with no surface manifestations. At Earthscope sampling scales, several low-resistivity lineaments in the deep crust project from the east to the Cascades, most prominently perhaps beneath Three Sisters. Structural geology analysis facilitated by growing LiDAR coverage is revealing numerous new faults confirming that seemingly regional NW-SE fault trends intersect N-S, Cascades graben- related faults in areas of known hot springs including Breitenbush. -
The Mountaineer
The Mountaineer 145 ture and making explorations, he was cherishing a plan to examine the Columbia River "from snowflake to brine." He did that very thing and it is claimed that he is the first man to make the entire journey. His adventures, his descriptions of the varying features of the great river, his references to historic explorers of the past, all these combine to make his book a worth while addition to the literature of the Pacific Northwest. The Mountaineer. Edited by MISS LULIE NETTLETON. (Seattle: The Mountaineers, 1921. Pp. 90.) Mazama. Edited by MISS ELLA P. ROBERTS. (Portland: The Mazamas, 1921. Pp. 89.) Mountain climbers in the Pacific Northwest await longingly each year for the appearance of these two books. Always the cen ter of interest in each book is the record of the club's outing during the summer of that year. Other records of mountaineering are in cluded and completed files of these publications are highly prized by librarians and other discriminating collectors. In the summer of 1921, The Mountaineers visited Glacier Peak and Lake Chelan. The story of the outing is told by Robert Walkinshaw and the illustrations are from photographs by members of the party. Other articles include the folowing: "Some Birds and Mammals of Mount Rainier" by Walter P. Taylor, of the Unit ed States Biological Survey; "Valley of Ten Thousand Smokes", by Rodney L. Glisan; "An Ascent of Mount Olympus in Thessaly", by Francis P. Farquhar; "A Mountaineer's Pilgrimage to Pales tine", by William B. Remey; "Light Weight Commissary for Back Packing", by Stuart P. -
