Map showing sampled radiolarian localities in the western Paleozoic and Triassic belt, Klamath Mountains, California
The western Paleozoic and Triassic belt, the largest of several major subdivisions of the Klamath Mountains geologic province, extends 300 km northward from the south end of the province in California to the north end of the province in Oregon (see inset map). The rocks of the belt are mainly sedimentary and volcanic, including tuff, cherty tuff, chert, argillite, limestone, and volcanic flows and
Map showing selected surface-water data for the Alton-Kolob coal-fields area, Utah
This is one of a series of maps that describe the geology and related natural resources of the Alton-Kolob coal-fields area, Utah. Streamflow records used to compile the map and the following table were collected by the U.S. Geological Survey in cooperation with the Utah Department of Natural Resources, Division of Water Rights, and the Utah Department of Transportation. The principal runoff-produ
Map showing some potential effects of petroleum spills on shorelines of the Port Townsend quadrangle, central Puget Sound region, Washington
Waterborne transport of crude oil into the Puget Sound region has increased rapidly since 1972 and may take another sharp increase during the next few years. In 1972, waterborne delivery of petroleum averaged 45,000 bdp (barrels per day); by 1972, the average had increased to 105,000 bpd (Pizzo and others, 1978, p. 19). Previously, most of the incoming petroleum was
Map showing surface ruptures associated with the Mammoth Lakes, California, earthquakes of May 1980
This map shows surface ruptures associated with the M 6 Mammoth Lakes earthquakes of May 25-27, 1980 (Sherburne, 1980). The ruptures were mapped during USGS field investigations May 28 to June 4 and July 14-19, 1980. The map also includes some of the ruptures recorded by California Division of Mines and Geology investigators May 26-31, June 26-27, and July 7-11, 1980 (Taylor and Bryant, 1980). Bec
