DDS-12 provides literal snapshot views of Colorado and Utah mining operations, generally before 1980. It supports environmental and historical research by providing access to the mostly unpublished photographs in the U.S. Geological Survey Photographic Library (USGS) collection in Denver. This material is provided to answer requests from government and historical researchers for visual documentation applicable to their current research.
The photographs were originally taken to support USGS reports on mineral resources in various mining districts or locales. The images provide a thorough search of the Photographic Library card catalog for Colorado and Utah mining operations. The database includes only views cataloged prior to 1990. For newer material or assistance, you are encouraged to visit the Photographic Library.
Captions reflect USGS research needs. USGS published captions are given preference and referenced to the publication. Otherwise captions are those provided by the geologist at the time of transfer to the library.
Circa dates may be inaccurate by as many as 5 years. Stratigraphic nomenclature is that used at the time the photograph was deposited.
DDS-12 is part of the ongoing work of the Survey to provide earth science information for the "common defense and general welfare," as stated in the Organic Act of 1879.
The Photographic Library has its origins in J.K. Hillers' Geological Survey Photographic Laboratory of the 1880's. Between 1900 and 1946, a major portion of the collection resided in the Topographic Division as part of the Map Reproduction Section. In 1946, the collection was transferred to the Survey's Library in Washington, D.C., and was moved to Denver in 1954.
The first attempt at cataloging the collection was made around 1900 by a committee of geologists chaired by N.H. Darton. This committee established the use of State-County (Country-Province) as the main finding system. This system and the geologist-photographer filing system have been maintained. In the mid-1950's, a librarian began systematically cataloging photographs using an accepted glossary of geologic terms and Library of Congress Headings.
We gratefully acknowledge Nelson H. Darton, who first began to catalog the Geological Survey's Photographic Laboratory's collection about 1900. Many of the subjects currently in use are directly related to his committee's work.
We acknowledge Marjorie E. Dalechek, a former Photographic Librarian, who dedicated 25 years to establishing cataloging, preservation, and customer procedures and without whom this collection probably would not exist.
We gratefully acknowledge the Geological Survey scientists who diligently provided both photographs and captions when they deposited their material with the Library or Photographic Laboratory during the past 100 years.
We thank Nancy Papazian and Frances Steele, Volunteers for Science, for their many hours of word-processing the photo captions from the various albums into our system.
We thank all the senior Geological Survey managers, scientists and others who directly and indirectly supported this project.
Some photographs included in this collection were published in the following U.S. Geological Survey publications. This list is provided to assist users in finding additional Geological Survey information on mining in Colorado and Utah.
