' 1 i BB 1, Ti 9 11 Pondering a workbook problem, students try to determine the dip and strike of folds, faulfe, anticlines, and synclines in a session. Jerry Smith, sophomore, studies a model showing geomorphology or gla- ciation. These models are used in class- es to help students recognize geologic changes. Geology Lecture Classes Enormous Three field trips to central Texas locations lured more than 150 students of GEOLOGY under the direction of Dr. John Sandidge, Department chairman. Each of the two introductory geology classes visited Llano and Mason counties where they saw, among other geological formations, the Enchanted Rock, a gran- ite batholith whose size is deceiving. Several of the students who viewed this phenomenon said that since there is no other structure of comparable size, the rock looks smaller than it really is. It actually covers 640 acres. In May, second semester introduc- tory course students made an excursion to the Persons Oil Field and large sepa- rating plant in Falls City Oil Field and the Uranium field in northwestern Karnes County. Mary Lou Tamez and Bryan Dunlap, members of a general lab class, microscopically probe rocks to determine the types of fossils that are characteristic of such species. 130

Swinging gaily ttirough their routine, Brenda McTrusty, James Morris, Zane Aschbacher, and Patricia Woodward present a German contribution to the Foreign Language Assembly. ...Present Combined Assembly Since 700 students were enrolled in the Department, in the fall, three additions and two replacements were made to the teaching staff. Although the Department added one course, Portugese, this year, several others will be an- nexed in the fall. They are Japanese, in the Evening Divi- sion, an advanced Spanish course, and a short history of Soviet Russia. Also, language extension courses from the United States Air Force Academy will be offered at SAC in the fall for officers at area bases. Dr. William Samelson, chairman, has instituted month- ly departmental meetings at which regular business, in- structional techniques, and opinions are discussed, and in formal departmental research talks are presented. Walking proudly off the stage with one of the first department awards for being an outstanding French student is Martha Young. 129

Future geologists learn by doing, and SAC students and structure scale models in their study. Excursions Hold Student Interest Since enrollment went up 70 per cent in the fall, two class sections in General Geology of 90 and 85 students were taught along with eight laboratory class- es, trailing sections of 801 a b, and Ge- ology 618. The Department purchased films and slides on magnetism, gravity, ocean- ography, and one on the earth ' s interior as a visual aid for both General Geology and Invertebrate Paleontology students. In laboratory sessions students are taught to recognize rocks, fossils, and ge- ological structures found in rock for- mations. During short field trips, stu- dents toured San Pedro Park to examine the Austin Chalk formation and its rep- resentative fossils, as well as Bracken- ridge Park, Olmos Basin, and the coun- try north of the city as far as Camp Bull- Recognition of rock formations and their structures is an important part of geology. Here Michael Settles meas- ures the dip of a fault plane in San Ped- ro Park. Lab Students listen and watch intently as Mr. Clyde Dickinson ex- plains the origin and de%elopmeht of one of the mairy rock samples studied in geology. 131
