Geology Links

California Geological Survey
Find "information on the geology, natural resources and geologic hazards of California." Includes a history of this government body, news, educational materials, maps, and reports on topics such as mineral resources (including gold and hazardous minerals), earthquakes, landslides and erosion, and tsunamis. From the California Department of Conservation.

USGS Geology in the Parks
This "non-technical approach to geology" explains geologic maps, plate tectonics, rocks and minerals, geologic time, geomorphic provinces, sand dunes, caves, and coasts. Includes profiles of the geology of several national parks, a glossary, maps, animations, and other images. A collaboration between the U.S. Geological Survey (USGS) and the National Park Service.

Image Gallery for Geology
A collection of images of geologic phenomena designed "to supplement introductory geology classes." Photographs of volcanic and sedimentary rocks, folds and faults, weathering, and coastlines are included. Each entry has a brief explanation.

California Geography, Geology, Hazards, and Natural History Information
"This website presents selected examples of maps and educational reference materials about California." Features links to sites and maps of California showing population, population density, interstates and highways, physiographic provinces (such as the Sierra Nevada and Mojave Desert), parks, earthquake faults, volcanoes, landslides, and more. From the U.S. Geological Survey (USGS).

A Tapestry of Time and Terrain: The Union of Two Maps - Geology and Topography
Information about the topography and geology of the continental United States. A digital map contains the description for each geologic feature with information for the eras in which it was formed. "Rock of Ages" is a timeline of each geologic era linked to the regions of the map. "Boundaries" shows two more maps: one with geomorphic, or physiographic, regions; the other with state boundaries. From the U.S. Geological Survey (USGS).

Geology.com
Material about geology and earth sciences, including maps and discussions of a wide variety of topics (such as meteor impact craters, rebuilding New Orleans, and waterfalls of the United States). Also includes a dictionary, an overview of geologic time, a mineral identification chart, materials for each state, and links to sites with geology jobs, geology news, and related material. Note: Includes some commercial matter. From a geology professor at Mansfield University, Pennsylvania.

Geologic Hazards
The Geologic Hazards Team is a part of the US Geological Survey (USGS) which researches the causes of landslides, earthquakes, and other geological phenomena. This site has three main sections: geomagnetism, landslides, and earthquakes. There are also Java-driven interactive maps of Western States Faults and National Earthquake Hazards.
