Preliminary photointerpretation map of landslide and other surficial deposits of the Mount Vaca, Vacaville, and parts of Courtland, Davis, Lake Berryessa, and Woodland 15-minute quadrangles, Napa and Solano counties, California Preliminary photointerpretation map of landslide and other surficial deposits of the Mount Vaca, Vacaville, and parts of Courtland, Davis, Lake Berryessa, and Woodland 15-minute quadrangles, Napa and Solano counties, California

This map presents preliminary information about the distribution and general character of landslides and other surficial deposits. When used in combination with other types of information, such as data on soils, bedrock geology, slopes, seismic response, hydrology, vegetation and climatic variation, it should be easier to arrive at sound decisions regarding the physical aspects of land...

Preliminary residual magnetic map of the eastern Bering Shelf and parts of western Alaska Preliminary residual magnetic map of the eastern Bering Shelf and parts of western Alaska

Residual magnetic anomalies for the offshore data were calculated by subtracting the Earth's main dipole field, adjusted for secular variations (based on the International Geomagnetic Reference Field (IGRF), epoch 1965, Fabiano and Peddie, 1969), from the observed values of the surveys listed below. The effects of diurnal variations and magnetic storms have been ignored. Individual...
