2002, Arizona Geological Survey
Remapping of the intramontane depression south of Kearny drained by Hackberry Wash and Indian Camp Wash between the Ripsey Hill and Crozier Peak spurs of the Tortilla Mountains was undertaken to reconcile differences in previous mapping, and to resolve questions raised or left open by the previous...
2001, California Geological Survey
Small to moderate eruptions that have occurred near the resort community of Mammoth Lakes, eastern California, along the Mono-Inyo Craters volcanic chain over the past 5,000 years can be anticipated to recur in the future. Such eruptions have produced phreatic blasts, lava domes and flows, fallout...
2001, California Geological Survey
Between 1964 and 1969 cinnabar was mined from the Gambonini mercury mine in northern California. The ore was extracted from an open pit, and approximately 275,000 cubic yards of overburden and other mine waste were dumped onto steep slopes adjacent to the pit. Following mine closure, the mine waste...
2001, California Geological Survey
Health officials of the State of California and the U.S. Environmental Protection Agency have identified potential health hazards from naturally occurring asbestos in most counties of the Sierra Nevada and Klamath Mountains. Asbestos minerals are a class A carcinogen. The asbestiform minerals...
2001, California Geological Survey
Erosion of sea cliffs along the central California coastline has become a major concern for public and private improvements constructed in harm's way. Stability of the local sea cliff is adversely affected by young, poorly consolidated sediments comprising the bluff, vulnerability to wave...
2001, California Geological Survey
In 1985 a Volkswagen sedan traveling north on Highway 101 at Petaluma collided with a horse. The horse ("Cisco") was killed, the young male driver became a paraplegic, and litigation ensued. The horse apparently broke through or stepped over a fence that was about 1.5 ft shorter than...
2001, California Geological Survey
The Seismic Hazard Mapping Project of the California Department of Conservation, Division of Mines and Geology (DMG), evaluates seismic hazards and designates zones of required seismic investigation. Within these zones, state law requires that site-specific geotechnical investigations be performed...
2001, California Geological Survey
2001, California Geological Survey
2001, California Geological Survey
Problems associated with spread foundations on shallow soils in the Sierra Nevada include ground freezing and associated frost heave, damming of water flowing along the soil/bedrock interface behind foundations, water seepage into crawl spaces, slope instability and backfill settlement as soils...
2001, California Geological Survey
The best and the most reliable methods available for the treatment and disposal of domestic sewage use designs and natural materials suited to the local geologic environment. Therefore, mapping and testing of the local geologic, hydrogeologic, and topographic conditions are critical to the...
2001, California Geological Survey
Established methods for paleontologic resource impact mitigation (PRIM) can preserve California's fossil heritage without stopping excavation or construction. Federal, state, and local legislation recognizes that fossils are significant non-renewable resources that need to be protected from...
2001, California Geological Survey
Geological engineering input was essential to the success of a student housing project on the University of California campus in Berkeley, California. Design considerations included (1) identifying zones of active, Holocene faulting, and establishing setbacks from these zones, (2) evaluating...
2001, California Geological Survey
Large-scale hillside developments in metavolcanic terrain typically present a range of geotechnical problems; a development in the geologically complex foothills of the Sierra Nevada is a good example. The geotechnical problems and best-practice solutions associated with this metavolcanic hillside...
2001, California Geological Survey
2001, California Geological Survey
The geologic conditions, design of temporary and permanent ground support, and methods of excavation and dewatering are summarized for the 5.6-mile long segment of the Bay Area Rapid Transit District's original line, between the foot of Market Street and Colonial Way in San Francisco. An...
2001, California Geological Survey
The Bay Area Rapid Transit (BART) system evolved between 1947-1962, centered on the concept of providing a high-speed commuter rail link with San Francisco and Oakland, across central San Francisco Bay. A joint-venture team of consultants was organized by BART to develop a scheme to cross beneath...
2001, California Geological Survey
This article describes various geologic challenges faced in the design, construction and ongoing maintenance of BART's 3.1 mile long Berkeley Hills twin tunnels, along the Contra Costa line, between the Rockridge and Orinda stations. These challenges included: (1) dealing with the unexpected...
2001, California Geological Survey
During the 1980's and 1990's, the City of San Francisco built a series of large underground structures to increase sewage treatment capacity and reduce the number of overflows into the Pacific Ocean to acceptable levels. One feature of this project was the Lake Merced Transport Tunnel,...
2001, California Geological Survey
The 340-meter long Islais Creek tunnels are part of the Islais Creek transport/storage project, a series of combined sewers in southeast San Francisco designed to reduce discharges into San Francisco Bay during storms. The project involved tunneling through Bay Mud, a well-known and troublesome...

About the Geological Surveys Database
https://statesurveys.americangeosciences.org

As of July 2018, the Geological Surveys Database replaces the Critical Issues Research Database, providing an improved portal for decision makers and others to locate and comprehensively search state geological survey publications and U.S. Geological Survey factsheets.

The Geological Surveys Database provides full-text searching of publications meaning that users can not only search metadata fields (i.e., title, author, notes, etc.), but also search against the entire text of the publications in the database in order to find the information they are seeking. The database also features interactive geographic searching of publications that have geographic coordinates, browsing of publications, faceted searching, and more.

Record display views include robust metadata that is based on a combination of GeoRef metadata that is supplemented with additional metadata from the state geological surveys and U.S. Geological Survey, links to state geological survey websites, suggestions for similar items, and a map display of associated geographic metadata coordinates.

The Geological Surveys Database also provides a wide array of user features including the ability to export citations, create user accounts to save queries, citations and create curated lists, add comments and custom tags to records in the database, and more.

The Geological Surveys Database is a collaborative effort between the American Geosciences Institute and U.S. state geological surveys to help increase the discoverability and use of geological survey publications by decision makers as they address issues at the intersection of the geosciences and society.
