Hydrogeology and ground-water flow at Levee 31N, Miami-Dade County, Florida, July 2003 to May 2004: As part of the Comprehensive Everglades Restoration Plan Hydrogeology and ground-water flow at Levee 31N, Miami-Dade County, Florida, July 2003 to May 2004: As part of the Comprehensive Everglades Restoration Plan
Introduction The Levee 31N Seepage Management Pilot Project began in 2001, as part of the Comprehensive Everglades Restoration Plan (CERP). The pilot project seeks to determine the appropriate technology needed to control seepage from Everglades National Park (ENP), and provide the appropriate amount of ground-water flow to minimize potential impacts to the West Well Field and Biscayne...
Geologic map of the Verdi Peak Quadrangle, Elko County, Nevada Geologic map of the Verdi Peak Quadrangle, Elko County, Nevada
A 1:24,000-scale, full-color geologic map of the Verdi Peak 7.5-minute quadrangle in Elko County, Nevada, with one cross section and descriptions of 19 rock units. Accompanying text describes the geology of the quadrangle.
Geologic map of the Lower Grand Wash cliffs and vicinity, Mohave County, Northwestern Arizona Geologic map of the Lower Grand Wash cliffs and vicinity, Mohave County, Northwestern Arizona
This digital map database is compiled from unpublished data and new mapping by the authors and represents the general distribution of surficial and bedrock geology in the mapped area. Together with the accompanying pamphlet, it provides current information on the geologic structure and stratigraphy of the area. The database dilineates map units that are identified by age and lithology...
Topographic Map of the Ophir and Central Candor Chasmata Region of Mars MTM 500k -05/287E OMKT Topographic Map of the Ophir and Central Candor Chasmata Region of Mars MTM 500k -05/287E OMKT
This map, compiled photogrammetrically from Viking Orbiter stereo image pairs, is part of a series of topographic maps of areas of special scientific interest on Mars. The figure of Mars used for the computation of the map projection is an oblate spheroid (flattening of 1/176.875) with an equatorial radius of 3396.0 km and a polar radius of 3376.8 km. The datum (the 0-km contour line)...

Geologic map of Gunnison Gorge National Conservation Area, Delta and Montrose Counties, Colorado Geologic map of Gunnison Gorge National Conservation Area, Delta and Montrose Counties, Colorado
This publication consists of a geologic map database and printed map sheet. The map sheet has a geologic map as the center piece, and accompanying text describes (1) the various geological units, (2) the uplift history of the region and how it relates to canyon downcutting, (3) the ecology of the gorge, and (4) human history. The map is intended to be used by the general public as well...
Earthquakes and faults in the San Francisco Bay area (1970-2003) Earthquakes and faults in the San Francisco Bay area (1970-2003)
The map depicts both active and inactive faults and earthquakes magnitude 1.5 to 7.0 in the greater San Francisco Bay area. Twenty-two earthquakes magnitude 5.0 and greater are indicated on the map and listed chronologically in an accompanying table. The data are compiled from records from 1970-2003. The bathymetry was generated from a digital version of NOAA maps and hydrogeographic...
