Still trying to sort through the confusion of rocks and minerals that make up the Bay Area? Then you might want to visit the Menlo Park offices of the U.S. Geological Survey. Stop by the library’s California Center to see the display of common Bay Area rocks and minerals; browse through their collection of books, maps, and journals covering geology, ecology, water, soils, and mining; and view the aerial photography collection. The library is open to the public for reference use and all services are available through interlibrary loans; for teachers, there’s also a special educational resources room. The Earth Sciences Information Center sells topographic and geologic maps, books, and other USGS publications. Visitors are welcome from 8 a.m. to 4 p.m., Monday through Friday. Be sure to pick up a copy of the new self-guided facilities tour guide in the lobby of Building 3, located near the main entrance at 345 Middlefield Road in Menlo Park. USGS also has a virtual library of information available through its website at www.usgs.gov.
