Discovery interfaces to Air Photos of Colorado
The Library has a large collection (164,000+) of aerial photographs of Colorado (no other states are collected). Most were shot from the mid-1930s through the early 2000s for the U.S. Forest Service, U.S. Geological Survey, U.S. Soil Conservation Service, and Bureau of Land Management (BLM). Mines does have some unique photos, most noteworthy from the early 1930s of the Front Range area take by the Lowry Field Photographers School. Other than the Denver area and the National Forests of Colorado, the Library has very few recent aerial photos.
The Library has created 3 discovery interfaces for its air photo collection. Each interface covers different photos in the collection.
Additional, paper indexes to the air photo sets are located in the green map cases in the Map Room. Some of the photographs have no indexes and some of the indexes have no photographs.
All of the air photos sets are listed in the Library's Catalog. To find aerial photographs of parts of Colorado, search for "[county] name" and "aerial photographs." The photos are located in blue, plastic boxes on the compact shelving units in the Map Collection. The photographs are filed by set. Most of the aerial photographs call numbers begin with "G4311.A4 svar .U5". While the aerial photographs may be checked out like books and maps, you must see the Map Librarian before you proceed to Circulation with the photos.
