O’Harra Collection, Glass Lantern Slides and Glass Plate Negatives SDSM&T Archives Devereaux Library South Dakota School of Mines & Technology Rapid City, SD 5/25/2016 SDSM&T Archives: C.C. O’Harra Collection, Glass Lantern Slides and Glass Plate Negatives page 1 Title C.C. O’Harra Collection: Glass Lantern Slides and Glass Plate Negatives Extent 1509 items: 1227 glass lantern slides, 282 glass plate negatives; 1358 unique images Scope and Content The C.C. O’Harra Collection consists of papers, publications, photographs, maps, and files of South Dakota School of Mines president and professor Cleophus Cisney O’Harra. The Devereaux Library’s glass lantern, sometimes referred to as magic lantern, collection consists of over 1200—3 ¼“ x 4” numbered slides and vary in subject matter from geology to meteorology to campus history and include photographs, drawings and maps of international, regional and historical interest. The glass plate negatives consist of 282 plates. The plates are of two size formats—4” x 5” and 5” x 7”, and have an unprotected photo emulsion on the back side. The purpose of the items was primarily instructional. They were produced either from a stationary camera, as shown in the photo or “on site” from a more portable unit. Glass plates were the first step in the reproduction process and, as is evidenced by the notations in the margins of many of the originals, were later submitted to a commercial photo processor to be made into glass slides Provenance The glass lantern slides and glass plate negatives have been a part of the university‘s holdings for several decades. -

Club Activities
Club Activities EDITEDBY FREDERICKO.JOHNSON A.A.C.. Cascade Section. The Cascade Section had an active year in 1979. Our Activities Committee organized a slide show by the well- known British climber Chris Bonington with over 700 people attending. A scheduled slide and movie presentation by Austrian Peter Habeler unfortunately was cancelled at the last minute owing to his illness. On-going activities during the spring included a continuation of the plan to replace old bolt belay and rappel anchors at Peshastin Pinnacles with new heavy-duty bolts. Peshastin Pinnacles is one of Washington’s best high-angle rock climbing areas and is used heavily in the spring and fall by climbers from the northwestern United States and Canada. Other spring activities included a pot-luck dinner and slides of the American Women’s Himalayan Expedition to Annapurna I by Joan Firey. In November Steve Swenson presented slides of his ascents of the Aiguille du Triolet, Les Droites, and the Grandes Jorasses in the Alps. At the annual banquet on December 7 special recognition was given to sec- tion members Jim Henriot, Lynn Buchanan, Ruth Mendenhall, Howard Stansbury, and Sean Rice for their contributions of time and energy to Club endeavors. The new chairman, John Mendenhall, was introduced, and a program of slides of the alpine-style ascent of Nuptse in the Nepal Himalaya was presented by Georges Bettembourg, followed by the film, Free Climb. Over 90 members and guests were in attendance. The Cascade Section Endowment Fund Committee succeeded in raising more than $5000 during 1979, to bring total donations to more than $12,000 with 42% of the members participating. -

Alaska Range
Alaska Range Introduction The heavily glacierized Alaska Range consists of a number of adjacent and discrete mountain ranges that extend in an arc more than 750 km long (figs. 1, 381). From east to west, named ranges include the Nutzotin, Mentas- ta, Amphitheater, Clearwater, Tokosha, Kichatna, Teocalli, Tordrillo, Terra Cotta, and Revelation Mountains. This arcuate mountain massif spans the area from the White River, just east of the Canadian Border, to Merrill Pass on the western side of Cook Inlet southwest of Anchorage. Many of the indi- Figure 381.—Index map of vidual ranges support glaciers.

Alaska Range glaciers extend in elevation from above 6,000 m, near the summit of Mount McKinley, to slightly more than 100 m above sea level at Capps and Triumvi- rate Glaciers in the southwestern part of the range. -

North American Notes
268 NORTH AMERICAN NOTES NORTH AMERICAN NOTES BY KENNETH A. HENDERSON HE year I 967 marked the Centennial celebration of the purchase of Alaska from Russia by the United States and the Centenary of the Articles of Confederation which formed the Canadian provinces into the Dominion of Canada. Thus both Alaska and Canada were in a mood to celebrate, and a part of this celebration was expressed · in an extremely active climbing season both in Alaska and the Yukon, where some of the highest mountains on the continent are located. While much of the officially sponsored mountaineering activity was concentrated in the border mountains between Alaska and the Yukon, there was intense activity all over Alaska as well. More information is now available on the first winter ascent of Mount McKinley mentioned in A.J. 72. 329. The team of eight was inter national in scope, a Frenchman, Swiss, German, Japanese, and New Zealander, the rest Americans. The successful group of three reached the summit on February 28 in typical Alaskan weather, -62° F. and winds of 35-40 knots. On their return they were stormbound at Denali Pass camp, I7,3oo ft. for seven days. For the forty days they were on the mountain temperatures averaged -35° to -40° F. (A.A.J. I6. 2I.) One of the most important attacks on McKinley in the summer of I967 was probably the three-pronged assault on the South face by the three parties under the general direction of Boyd Everett (A.A.J. I6. IO). The fourteen men flew in to the South east fork of the Kahiltna glacier on June 22 and split into three groups for the climbs. -
Resedimentation of the Late Holocene White River Tephra, Yukon Territory and Alaska
Resedimentation of the late Holocene White River tephra, Yukon Territory and Alaska K.D. West1 and J.A. Donaldson2 Carleton University3 West, K.D. and Donaldson, J.A. 2002. Resedimentation of the late Holocene White River tephra, Yukon Territory and Alaska. In: Yukon Exploration and Geology 2002, D.S. Emond, L.H. Weston and L.L. Lewis (eds.), Exploration and Geological Services Division, Yukon Region, Indian and Northern Affairs Canada, p. 239-247. ABSTRACT The Wrangell region of eastern Alaska represents a zone of extensive volcanism marked by intermittent pyroclastic activity during the late Holocene. The most recent and widely dispersed pyroclastic deposit in this area is the White River tephra, a distinct tephra-fall deposit covering 540 000 km2 in Alaska, Yukon, and the Northwest Territories. This deposit is the product of two Plinian eruptions from Mount Churchill, preserved in two distinct lobes, created ca. 1887 years B.P. (northern lobe) and 1147 years B.P. (eastern lobe). The tephra consists of distal primary air-fall deposits and proximal, locally resedimented volcaniclastic deposits. Distinctive layers such as the White River tephra provide important chronostratigraphic control and can be used to interpret the cultural and environmental impact of ancient large magnitude eruptions. The resedimentation of White River tephra has resulted in large-scale terraces, which fl ank the margins of Klutlan Glacier. Preliminary analysis of resedimented deposits demonstrates that the volcanic stratigraphy within individual terraces is complex and unique. RÉSUMÉ Au cours de l’Holocène tardif, des matériaux pyroclastiques ont été projetés lors d’importantes et nombreuses éruptions volcaniques, dans la région de Wrangell de l’est de l’Alaska. -
