Field mapping areas in Mojave Desert and Great Salt Lake regions on general map of the United States derived from the National Atlas

Current research is focusing on geologic mapping and neotectonic studies in the Great Salt Lake region along Wasatch Front and around the shorelines of ancient Lake Bonneville and the modern regional lake basins.

We are mapping young and active fault zones eastward from the recently studied Calico, Cady, Cave Mountain, and Manix faults. Regionally from west to east across the Eastern California Shear Zone (ECSZ), northwest-striking dextral faults are replaced by east-striking faults. These latter faults terminate into the Soda-Avawatz fault, the eastern boundary of the ECSZ. Although the locations of most young faults are known, none of the zones of interaction for the faults have been mapped, and details of the total offset and timing of activity along faults are poorly known. This problem is an excellent use of the geologic and geophysical mapping approach embodied by the National Cooperative Geologic Mapping Program.

Previous allied project and ongoing investigations focus on the neotectonics and fault system studies, desert ecosystem studies, and geologic mapping in the greater Mojave Desert region in southern California. See selected publications and map products associated with past and present research.
