An introduction to geology in the field, this course is the equivalent of GEOSCI/ENVIRON 118/119 but is taught at Camp Davis, the University's Rocky Mountain Field Station near Jackson, Wyoming. It stresses principles and processes involved in the evolution of the earth. The course includes rigorous laboratory exercises in which students study minerals, rocks and fossils, and structures in their natural settings. Lectures are given both in camp and in the field, but much time is spent outdoors in the nearby Teton, Hoback, Gros Ventre, and Snake River Ranges. Other trips of special significance include the Wind River Range. Craters of the Moon, and Yellowstone Park.
