Credit will not be given for both Geology 5 and Geology 21 or 54. AWS (5). 15. Rocks and Minerals—Sight recognition of the important rock-forming and other minerals through class discussion and laboratory work, and the identification of the common rocks of the earth's crust by mineral content, association and occurrence. Field trips are required. Three lectures and one laboratory period a week. A (4). Staff 21. Physical Geology—The earth, its rocks and minerals, its surface and subterranean features, their origin and causes as revealed in land features. Credit not given for both Geology 21 and Geology 5 or 54. Two field trips required. Four lectures and one laboratory period a week. AWS (5) Staff 22. Historical Geology—The history of the earth, from its theoretical origin to the present, as interpreted from the rocks and their fossil contents. North America, particularly Utah and the adjacent areas, is emphasized. Two required field trips provide a valuable supplement to class discussion. S (5). Staff 53.
