Geoscience Slide Show: 16,000 earth science pictures going back to 1868. ( -Welcome to the U.S. Geological Survey Photographic Archive. This on-line system provides access to over 22,300 photographs dating from 1868 to the present. This site is currently “under construction” and will change over the next several months. Photographs will be continually added. Captions are currently being edited for punctuation errors, misspellings, and accuracy. Many captions are vague and will remain so, as this is the only information the long-deceased geologist/photographer provided. The syntax of the late 1800's and early 1900's will be preserved and changed only to allow for clarity.
