Coastal-change and glaciological map of the Bakutis Coast, Antarctica: 1972-2002 Coastal-change and glaciological map of the Bakutis Coast, Antarctica: 1972-2002
Changes in the area and volume of the polar ice sheets are intricately linked to changes in global climate, and the resulting changes in sea level may severely impact the densely populated coastal regions on Earth. Loss of the West Antarctic part of the Antarctic ice sheet alone could cause a sea-level rise of approximately 6 m. The potential sea-level rise after melting of the entire...
Geologic Map of the Aino Planitia (V46) Quadrangle, Venus 1:5,000,000 Geologic Map of the Aino Planitia (V46) Quadrangle, Venus 1:5,000,000
The Aino Planitia quadrangle (V-46) extends from 25?-50? S. latitude, 60?-90? E. longitude. The quadrangle was mapped at 1:5,000,000 scale as part of the NASA Planetary Geologic Mapping Program. Aino Planitia is a lowland region in the southern hemisphere of Venus and is southwest of Thetis Regio in western Aphrodite Terra. It is dominated by low-lying plains units that are characterized...
Geologic map of the Bonners Ferry 30' x 60' quadrangle, Idaho and Montana Geologic map of the Bonners Ferry 30' x 60' quadrangle, Idaho and Montana
This data set maps and describes the geology of the Bonners Ferry 30' x 60' quadrangle, Idaho and Montana. The bedrock geology of the Bonners Ferry quadrangle consists of sedimentary, metamorphic, and granitic rocks ranging in age from Middle Proterozoic to Eocene. Bedrock units include rocks of (1) the Middle Proterozoic Belt Supergroup (2) the Middle Proterozoic Deer Trail Group, (3)...
Geologic map of the Fremont quadrangle, Shannon, Carter, and Oregon Counties, Missouri Geologic map of the Fremont quadrangle, Shannon, Carter, and Oregon Counties, Missouri
The bedrock exposed in the Fremont Quadrangle, Missouri, comprises 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 under the U.S. Geological...
Geologic map of the Horse Mountain Quadrangle, Garfield County, Colorado Geologic map of the Horse Mountain Quadrangle, Garfield County, Colorado
New 1:24,000-scale geologic map of the Horse Mountain 7.5' quadrangle, in support of the USGS Western Colorado I-70 Corridor Cooperative Geologic Mapping Project, summarizes available geologic information for the quadrangle. It provides new interpretations of the stratigraphy, structure, and geologic hazards in the area of the southwest flank of the White River uplift. Bedrock strata...
Geologic map of the Lower Hurricane Wash and vicinity, Mohave County, Northwestern Arizona Geologic map of the Lower Hurricane Wash and vicinity, Mohave County, Northwestern Arizona
This digital map database is compiled from published open file reports, and new mapping by the author, and represents the general distribution of surficial and bedrock geology in the mapped area. The map area lies within the Shivwits and Uinkaret Plateaus, subplateaus of the southwestern part of the Colorado Plateau hypsographic province. Together with the accompanying pamphlet, it...
Geologic map of the MTM 85080 Quadrangle, Chasma Boreale Region of Mars Geologic map of the MTM 85080 Quadrangle, Chasma Boreale Region of Mars
The polar deposits on Mars probably record martian climate history over the last 107 to 109 years (for example, Thomas and others, 1992). The area shown on this map includes polar layered deposits and polar ice, as well as some outcrops of older, underlying terrain. This quadrangle was mapped using Viking Orbiter images in order to study the relations among erosional and depositional...
Geologic map of the Puye Quadrangle, Los Alamos, Rio Arriba, Sandoval, and Santa Fe Counties, New Mexico Geologic map of the Puye Quadrangle, Los Alamos, Rio Arriba, Sandoval, and Santa Fe Counties, New Mexico
The Puye quadrangle covers an area on the eastern flank of the Jemez Mountains, north of Los Alamos and west of Espanola, New Mexico. Most of the quadrangle consists of a dissected plateau that was formed on the resistant caprock of the Bandelier Tuff, which was erupted from the Valles caldera approximately 1 to 2 million years ago. Within the canyons of the east-flowing streams that
Geologic map of the Rusalka Planitia Quadrangle (V-25), Venus Geologic map of the Rusalka Planitia Quadrangle (V-25), Venus
The Rusalka Planitia quadrangle (herein referred to as V-25) occupies an 8.1 million square kilometer swath of lowlands nestled within the eastern highlands of Aphrodite Terra on Venus. The region (25?-0? N., 150?-180? E.) is framed by the crustal plateau Thetis Regio to the southwest, the coronae of the Diana-Dali chasmata complex to the south, and volcanic rise Atla Regio to the west...
