Organization Title


California Geological Survey (CGS) believes that there is a need to increase public awareness and understanding of the importance of the earth sciences in our lives. CGS has developed the Educational Resources Center for students, teachers, and all others with an interest in the hope of making earth science learning more fun, intriguing, and meaningful. The column on the left provides links to more technical California geologic information from CGS while the information below is of a more generalized nature. We encourage you to browse both resources. Please let us know how we may better serve you at the Educational Resources Center.

"California Geology 101


The California Geotour is an interactive index of Web pages of geologic field trip guides and related Web sites compiled by CGS for the benefit of all who have wondered about California's geologic features. The digital field trip guides are grouped according to the geologic province in which they occur. Each field trip generally includes geologic information, photographs, maps, text and directions to local natural features throughout the state. This is the place to get an arm chair view of California's geology.  Click on the icon to begin The California Geotour.
