Atlas of natural hazards in the Hawaiian coastal zone
The purpose of this report is to communicate to citizens and regulatory authorities the history and relative intensity of coastal hazards in Hawaii. This information is the key to the wise use and management of coastal resources. The information contained in this document,we hope,will improve the ability of Hawaiian citizens and visitors to safely enjoy the coast and provide a strong data set for
Backscatter Intensity and Sun-Illuminated Sea Floor Topography of Quadrangles 1 and 2
The Great South Channel separates the western part of Georges Bank from Nantucket Shoals and is a major conduit for the exchange of water between the Gulf of Maine to the north and the Atlantic Ocean to the south. Water depths range mostly between 65 and 80 m in the region. A minimum depth of 45 m occurs in the east-central part of the mapped area, and a maximum depth of 100 m occurs in the northw

Geologic and aeromagnetic maps of the Fossil Ridge area and vicinity, Gunnison County, Colorado
This data set includes a GIS geologic map database
of an Early Proterozoic metavolcanic and metasedimentary terrane
extensively intruded by Early and Middle Proterozoic granitic
plutons. Laramide to Tertiary deformation and intrusion of
felsic plutons have created numerous small mineral deposits that
are described in the tables and are shown on the figures in the
accompanying text p
Geologic map and map database of northeastern San Francisco Bay region, California: Most of Solano County and parts of Napa, Marin, Contra Costa, San Joaquin, Sacramento, Yolo, and Sonoma Counties
This digital map database, compiled from previously published and unpublished data, and new mapping by the authors, represents the general distribution of bedrock and surficial deposits in the mapped area. Together with the accompanying text file (nesfmf.ps, nesfmf.pdf, nesfmf.txt), it provides current information on the geologic structure and stratigraphy of the area covered. The database delin
Geologic map and map database of western Sonoma, northernmost Marin, and southernmost Mendocino counties, California
This digital map database, compiled from previously published and unpublished data, and new mapping by the authors, represents the general distribution of bedrock and surficial deposits in the mapped area. Together with the accompanying text file (wsomf.ps, wsomf.pdf, wsomf.txt), it provides current information on the geologic structure and stratigraphy of the area covered. The database delineates
Geologic map of the Bernalillo NW quadrangle, Sandoval County, New Mexico
The Bernalillo NW quadrangle is located in the northern part of the Albuquerque basin, which is the largest basin or graben within the Rio Grande rift. The quadrangle is underlain by poorly consolidated sedimentary rocks of the Santa Fe Group. These rocks are best exposed in the southwestern part of the quadrangle in the Rincones de Zia, a badland topography cut by northward-flowing tributary arr

Geologic map of the Dillon quadrangle, Summit and Grand Counties, Colorado
New 1:24,000-scale geologic mapping along the Interstate-70 urban corridor in western Colorado, in support of the USGS Central Region State/USGS Cooperative Geologic Mapping Project, is contributing to a more complete understanding of the stratigraphy, structure, tectonic evolution, and hazard potential of this rapidly developing region. The 1:24,000-scale Dillon quadrangle is near the headwaters

Geologic Map of the Izzenhood Spring Quadrangle, Lander County, Nevada
The Izzenhood Spring quadrangle covers about 145 km2 of the southwestern part of the Sheep Creek Range in northern Lander County, Nevada. The quadrangle is underlain by Lower Paleozoic rocks that are unconformably overlain and intruded by thick sequences of Miocene igneous rocks related to the northern Nevada rift (Stewart and McKee, 1977; Wallace and John, 1998; John and others, 2000). Much of th
Geologic Map of the Katmai Volcanic Cluster, Katmai National Park, Alaska
This digital publication contains all the geologic map information used to publish U.S. Geological Survey Geologic Investigations Map Series I-2778 (Hildreth and Fierstein, 2003). This is a geologic map of the Katmai volcanic cluster on the Alaska Peninsula (including Mount Katmai, Trident Volcano, Mount Mageik, Mount Martin, Mount Griggs, Snowy Mountain, Alagogshak volcano, and Novarupta volcano)
