This course examines the spectacular geology along a 32-mile stretch of the Colorado River between Fruita, Colorado and Westwater, Utah. Along with basic concepts of geology, the formations exposed in this portion of the eastern Colorado Plateau, including their ages, rock types and origins, are discussed. Historical geology and geomorphology come to life in this geologic wonderland. Students study the lava flows exposed in the area and determine their source area. The problems of mid-continent magma genesis and its relationship to plate tectonics are also explored.
Students study the pyroclastic deposits exposed in the area and determine the sequence of events.
The problems of mid-continent magma genesis and its relationship to plate tectonics are also explored. This course is an introduction to the science of land navigation. There are required field exercises. This course examines minerals and rocks that make up the Earth s crust, including their origin, occurrence and identification. In addition to the recognition of hand specimens, this course utilizes the petrographic microscope and X-ray crystallography to identify minerals and rocks.
