Investigations of the dune fields allow students to identify various types of dunes, as well as damage related to desertification. The relationships of sand source areas, cross-bedding and transport directions are investigated. 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.
