The database was developed as a contribution to the National Cooperative Geologic Mapping Program's National Geologic Map Database, and is intended to provide a general geologic setting of the Yucaipa quadrangle. The database and map provide information about earth materials and geologic structures, including faults and folds that have developed in the quadrangle due to complexities in the San Andreas Fault system. The Yucaipa 7. Stratigraphic and structural elements include: 1 strands of the San Andreas Fault that bound far-traveled terranes of crystalline and sedimentary rock; 2 Mesozoic crystalline rocks that form lower and upper plates of the regionwide Vincent-Orocopia Thrust system; and 3 late Tertiary and Quaternary sedimentary materials and geologic structures that formed during the last million years or so and that record complex geologic interactions within the San Andreas Fault system.
These materials and the structures that deform them provide the geologic framework for investigations of geologic hazards and ground-water recharge and subsurface flow. Geologic information contained in the Yucaipa database is general-purpose data that is applicable to land-related investigations in the earth and biological sciences.
The term "generalpurpose" means that all geologic-feature classes have minimal information content adequate to characterize their general geologic characteristics and to interpret their general geologic history. However, no single feature class has enough information to definitively characterize its properties and origin. For this reason the database cannot be used for site-specific geologic evaluations, although it can be used to plan and guide investigations at the site-specific level.

What is this rock? Are there old volcanoes in Vermont? What is the smell in my water? Is it dangerous? Can I fix it? Is there oil or natural gas on my property? What is the likelihood of failure along this stream bank? Are there hazardous areas in Smugglers Notch?
How can we mitigate the landslide area in Jeffersonville? Is there a buried aquifer in my town? Are there favorable areas for my water supply? See Minnesota's report for information about using geologic maps to solve community problems.
Want to locate a public water supply or drill a private well? And yet only about of those quads are available as geologic maps at the standard, scale of , 1 inch equals feet. Clearly, not all of New Mexico needs mapping at that scale. But, in the past, geologic mapping was not concentrated in the settled regions, such as along the Rio Grande and other major rivers.
Instead, maps were made in mining districts and in areas of noteworthy scientific investigations. Recently, however, economic development and unprecedented growth of communities within the Rio Grande watershed have resulted in growing pressures to utilize our natural resources. It is critically important for communities and agencies to have access to modern and accurate scientific data concerning their environment.
Much of the mapping that we undertake is directed toward providing such information.
