Show Titles and Abstracts 9 Wasatch Range on the west side of Cache Valley) tentatively reveal existence of 12 or more small cliff, cirque, and alpine glaciers or glacierets, in addition to a number of neve fields, during Pleistocene time. At least six of these glaciers reached maximum lengths of over one mile, the longest (in Pine Canyon) being near ly three miles. Four canyons on the eastern side of the mountain (the middle and north branches of Pine Canyon, and Brush and Shumway Canyons), and two or more on the western side (Jim May and an unnamed canyon) show evidence of at least two glacial stages. Deep Canyon, on the northeast, the south branch of Pine Canyon, on the east, and Cottonwood, Coldwater, and perhaps Three Drag Road Canyons on the west side of 'the mountain show evidence of but a single, presumably early glacial stage. On the east side of the mountain the Pine Canyon glacier and perhaps also the Shumway Canyon glacier reached to the level of Lake Bonneville (5200), the morainal debris atthe mouth of Pine Canyon showing evidence of being reworked by wave No glaciers on the west side reached as low as the action. Bonneville Lake level. The glaciers initiated at elevations from 8500 to slightly over 9000 feet. It is suggested that the low level to which these glaciers descended is largely due to the unusually steep gradient, since the glaciers were comparatively small in size, and the catchment areas unusually restricted in area.

Buranek Utah State Department of Publicity and Industrial Development, Salt Lake City, Utah The Historical Background of Geology and Its Value Walter R. Buss Weber College, Ogden, Utah Geology has a rich historical background, but little or no is given this phase in most college courses. Material for such classes is easily 'attainable. Four periods can be recog nized, an ancient period from about 600 B. C. to 79 A. D.: a medieval period from 79 A. D. to about 1450 A. D.; the Renaissance, from 1450 to/1775 A. D.; and a modern period, 1775i to the present. Significant contributions were made to the science in each of these periods, and much interest can be aroused. The values are threefold: Geology is a living, growig field; many attention basic principles and axioms can be better understood; and it is a human approach. The history of the science is needed by all who take classes in this field. |
