University ('74-'76) Surficial geologic maps emphasize the location of deposits and landscape features that formed in response to a variety of geomorphic processes, both catastrophic and mundane. Many different surface processes are climatically driven and thus have time dependence that varies as a consequence of the different climate cycles over time. The impact from landscape modifying processes commonly results in movement of loose material of different origin. Surficial geologic maps show the areas of impact in a spatial context that includes temporal information. From this kind of information the location, magnitude and duration of large scale or catastrophic events can be recognized by the modification of the landscape or from the accompanying depositional record. The maps emphasize tectonically active features such as faults and volcanoes. They also show the spatial relation of tectonic features to groundwater discharge, geothermal systems and other geomorphic systems Recent Publications: Slemmons, D.B, Vittori, E., Jayko, A.S., Carver, G.A., and Bacon, S.N., 2008, Quaternary Fault and Lineament Map of Owens Valley, Inyo County, Eastern California: Geological Society of America Map and Chart Series 96, 2 sheets, scale:1:100,000, doi: 10.1130/2008.MCH096.
