The Alaska Geologic Data Index (AGDI) is the finding aid for the Anaconda Minerals Exploration Collection at ARLIS. AGDI is available on the website of the Division of Geological & Geophysical Surveys at maps.dggs.alaska.gov/agdi/. An extensive help file for AGDI is available at maps.dggs.alaska.gov/agdi/help/.
The AGDI is the successor to the AKMIDI database, which was formerly available on public computers at ARLIS. The AKMIDI database is still available for download in Microsoft Access format from Alaska Division of Geological & Geophysical Surveys.
The Anaconda Collection contains:
-About 300 published reports, including Anaconda progress reports.
-Field notes, data, analysis, geological reports, land status files, aerial photographs, and remote sensing data .
-Sample cards arranged by year, crew, and sampler.
-Maps, including 11,000 original mylars and blue lines, and topographic maps with geologists’ notes on them, indexed by quadrangle.
At ARLIS, the archive files are stored in folders inside hanging files, with matching file numbers, organized by quadrangle and prospect. Section AA is a larger regional group that precedes the quadrangles. “Sunshine files” are at the end of the files facing the windows.
In addition to Anaconda Collection items at ARLIS, AGDI and AKMIDI also reference materials located at Cook Inlet Region Inc. (CIRI) and at the Alaska Geologic Materials Center (GMC).
Each Anaconda Collection record refers to one of the three locations.
- ARLIS – The Anaconda Collection is kept in the locked files at the back of the library.
- CIRI – The prospect was on CIRI lands. The patron must contact CIRI.
- GMC – The item is a map at the Alaska Geological Materials Center in Eagle River. See more information on this below.
The Anaconda Collection includes 6,497 single page or sheet image files of maps and other documents. The images are identified by their numerical file names, which start at m0671.jpg and end with m15094.jpg. The image files are contained in a folder on the ARLIS document server at
Unfortunately, the Anaconda database records do not contain live links to the image files. The records, however, do contain references to the image file names, less the “jpg” file type ending. The catalog-id records in Anaconda embed the corresponding filename, with the exception of leading zeros. For examples, catalog ID T-CIRI-275-M10680 corresponds to the file m10680.jpg. Image files are also referenced in the dataset descriptions in some records.
Image files may be retrieved and saved by browsing the \Anaconda\Images folders until one reaches the image with the desired catalog ID.
Maps are housed at DGGS’s Alaska Geologic Materials Center in Eagle River and are available for viewing in an unheated structure, but cannot be borrowed. Arrangements can be made for Alaska Legal Copy to pick up maps, make copies, and return the originals to the GMC, at the patron’s expense. For varying fees, Digital Blueprint can copy the GMC maps onto paper, mylar or CD/DVD.
The GMC is open Monday through Friday, 8 a.m. to 4:30 p.m. and closed for lunch from noon to 12:30. Patrons are advised to call ahead to make an appointment. Contact:

The Anaconda Minerals Collection includes more than 10 years of minerals exploration data collected between 1974 and 1984 throughout Alaska by the Anaconda Minerals Company, as well as information collected by various other mining companies. It would cost tens of millions of dollars to redo this exploration effort, a testament to the value of this Collection.
The data set includes geological, geochemical, and geophysical reports, surveys, field notes, maps, and figures. Anaconda Collection maps and files from outside of the CIRI region were donated to the University of Alaska Anchorage (UAA). ARLIS houses the files, while DGGS’s Geologic Materials Center in Eagle River houses the over-sized maps and illustrations.
The index of the Anaconda Collection was designed and managed by professional geologists to ensure that the information required by minerals industry would be captured. It was created as part of the Minerals Data Information Rescue in Alaska (MDIRA) effort, often referred to as “Minerals At Risk”.
