Provided by the British Geological Survey, this site contains a database of some 6,400 digitized images drawn from the National Archive of Geological Photographs (NAGP). The archive may be searched by keyword, advanced search, or browsed via themed galleries (Montserrat Volcanic Eruption, Beltmoss Quarry - working stone, Aerial photographs in and around Edinburgh, etc.). Unfortunately, the images are only available in one, rather small, size. They are accompanied by information on location, photographer, geologist, year taken, and descriptions of varying length. Additional information on the British Geological Survey may be accessed from the main page.
