Geologic Map of Pipe Spring National Monument and the Western Kaibab-Paiute Indian Reservation, Mohave County, Arizona Geologic Map of Pipe Spring National Monument and the Western Kaibab-Paiute Indian Reservation, Mohave County, Arizona
The digital map publication, compiled from previously published and unpublished data and new mapping by the author, represents the general distribution of surficial and bedrock geology in Pipe Spring National Monument and vicinity, including the following 1:24,000-scale U.S. Geological Survey (USGS) quadrangles: Moccasin, Kaibab, Pipe Valley, and Pipe Spring. Together with the...
Geologic map of the Hebgen Lake quadrangle, Beaverhead, Madison, and Gallatin counties, Montana, Park and Teton counties, Wyoming, and Clark and Fremont counties, Idaho Geologic map of the Hebgen Lake quadrangle, Beaverhead, Madison, and Gallatin counties, Montana, Park and Teton counties, Wyoming, and Clark and Fremont counties, Idaho
The geology of the Hebgen Lake Quadrangle was mapped as part of an Ongoing research effort by the USGS to understand the geologic framework of the area in and around Yellowstone National Park. Prior to 1965 the regional geology was known only from reconnaissance surveys. Two important components of this effort are an evaluation of (1) the seismic risk hazard and (2) the mineral resource
Geologic Map of the Poverty Bay 7.5' quadrangle, King and Pierce counties, Washington Geologic Map of the Poverty Bay 7.5' quadrangle, King and Pierce counties, Washington
The Poverty Bay quadrangle lies near the center of the region?s intensively developing urban core. Less than 20 km north lies the city of Seattle; downtown Tacoma lies just southwest of the quadrangle. The map area expresses much of the tremendous range of Quaternary environments and deposits found throughout the central Puget Lowland. Much of the ground surface is mantled by a rolling...
Geologic map of the Umiat quadrangle, Alaska Geologic map of the Umiat quadrangle, Alaska
This geologic map of the Umiat quadrangle is a compilation of previously published USGS geologic maps and unpublished mapping done for the Richfield Oil Corporation. Geologic mapping from these three primary sources was augmented with additional unpublished map data from British Petroleum Company. This report incorporates recent revisions in stratigraphic nomenclature. Stratigraphic and...
Geologic map of the Van Buren South quadrangle, Carter County, Missouri Geologic map of the Van Buren South quadrangle, Carter County, Missouri
The bedrock exposed in the Van Buren South quadrangle, Missouri, comprises Late Cambrian and Early Ordovician aged dolomite, sandstone, and chert. The sedimentary rocks are nearly flat-lying except where they are adjacent to faults. The carbonate rocks are karstified and the area contains numerous sinkholes, springs, caves, and losing-streams. This map is one of several being produced...
Geology, tephrochronology, radiometric ages, and cross sections of the Mark West Springs 7.5' quadrangle, Sonoma and Napa counties, California Geology, tephrochronology, radiometric ages, and cross sections of the Mark West Springs 7.5' quadrangle, Sonoma and Napa counties, California
The purpose of this geologic map is to provide a context within which to interpret the Neogene evolution of the active strike-slip fault system traversing the Mark West Springs 7.5' quadrangle and adjacent areas. Based on this geologic framework, the timing and total amounts of displacement and the Neogene rates of slip for faults of the right-stepover area between the Healdsburg and...
