Geologic and geophysical maps of the Las Vegas 30' x 60' quadrangle, Clark and Nye counties, Nevada, and Inyo County, California
Las Vegas and Pahrump are two of the fastest growing cities in the US, and the shortage of water looms as among the greatest future problems for these cities. These new maps of the Las Vegas 30 x 60-minute quadrangle provide a geologic and geophysical framework and fundamental earth science database needed to address societal issues such as ground water supply and contamination, surface flood, la

Seismic-hazard maps for the conterminous United States
This publication consists of six map sheets (titles and text included in this document, below), geospatial datasets, and metadata. The geospatial datasets consist of ArcInfo export files for the seismic-hazard point and polygon data shown on the sheets.
Probabilistic seismic-hazard maps were prepared for the conterminous United States portraying peak horizontal acceleration and horizontal spectra
Geologic map of Cydonia Mensae - southern Acidalia Planitia, Mars, quadrangles MTM 40007, 40012, 40017, 45007, 45012, and 45017
Cydonia Mensae lie adjacent to the boundary separating the highland terrain of western Arabia Terra from the northern lowlands (the dichotomy boundary), where this boundary is gradational rather than abrupt, as is generally the case. Cydonia Mensae are characterized by abundant knobs and mesas, most of which occur in well defined clusters that commonly are long and narrow. The adjacent lowland of
Precambrian crystalline basement map of Idaho: An interpretation of aeromagnetic anomalies
Idaho lies within the northern sector of the U.S. Cordillera astride the
boundary between the Proterozoic continent (Laurentia) to the east and
the Permian to Jurassic accreted terranes to the west. The continental
basement is mostly covered by relatively undeformed Mesoproterozoic
metasedimentary rocks and intruded or covered by Phanerozoic igneous

Principal faults in the Houston, Texas, metropolitan area
SummaryThis report, prepared by the U.S. Geological Survey in cooperation with the Harris-Galveston Coastal Subsidence District, documents and refines the locations of principal faults mapped in the Houston, Texas, metropolitan area in previous studies. Numerous subsurface faults have been documented beneath the Houston metropolitan area at depths of 3,200 to 13,000 feet. Some of these subsurface
Topographic map of part of the Kasei Valles and Sacra Fossae regions of Mars - MTM 500k 20/287E OMKT
This map is part of a series of topographic maps of areas of special scientific interest on Mars. The topography was compiled photogrammetrically using Viking Orbiter stereo image pairs and photoclinometry from a Viking Orbiter image. The contour interval is 250 m. Horizontal and vertical control was established using the USGS Mars Digital Image Model 2.0 (MDIM 2.0) and data from the Mars Orbiter
Topographic map of the Coronae Montes region of Mars - MTM 500k -35/087E OMKTT
This map is part of a series of topographic maps of areas of special scientific interest on Mars. The topography was compiled photogrammetrically using Viking Orbiter stereo image pairs. The contour interval is 250 m. Horizontal and vertical control was established using the USGS Mars Digital Image Model 2.0 (MDIM 2.0) and data from the Mars Orbiter Laser Altimeter (MOLA).
Results of land cover change detection analysis in and around Cordillera Azul National Park, Peru
The first product of the Optimizing Design and Management of Protected Areas for Conservation Project is a land cover change detection analysis based on Landsat thematic mapper (TM) and enhanced thematic mapper plus (ETM+) imagery collected at intervals between 1989 and 2002. The goal of this analysis was to quantify and analyze patterns of forest clearing, land conversion, and other disturbances
