Mine File Overlay Maps, by quadrangle name
- Publication Place: Anchorage, AK

- Originator: State of Alaska
- Description: This page links to scanned copies of Alaska Kardex location maps, made by the John Rishel Mineral Information Center. The original transparent overlays were used with U.S. Geological Survey 1:250,000 scale maps. The overlay scans include a topographic base. They were scanned at 250 dpi and saved in jpg file format. The Kardex information on the overlays reflects information at a particular time and is therefore dated. Not all Kardex information is necessarily presented on an overlay.These scans are to be used in conjunction with Kardex file scans published by the BLM, publication BLM/AK/AE-03/003. This page links to records in jpg graphics format. The images in this collection are arranged in folders alphabetically by quadrangle name.
- This product is a result of the Minerals Data at Risk activity funded by the BLM. This dataset represents digital images of the Alaska Kardex files, a system developed by the State of Alaska and maintained as a paper-based system of tracking minerals information, especially mining claim activity, in Alaska. Records were established based on mineral locations and occurrences from published literature as well as from mining claim records from the recording districts. The records were developed from recorded documents, claim-location notices, affidavits of annual labor, and deeds received from the 34 recording districts in the state. The records have been used extensively by the mining industry, legal firms, native corporations, professional geologists, and state and federal agencies since 1953.
- Records were arranged serially within a geographic framework established by the 153 U.S.Geological Survey 1:250,000-scale quadrangles within Alaska. The quadrangles were numbered from North to South, in a sequence that was also used in later years by the U.S. Bureau of Mines to index quadrangles.Paper cross-references sorted by owner/operator, and claim name were created and kept in Fairbanks at Department of Natural Resources (DNR) offices over the years. The U.S. Bureau of Mines created and for several years maintained transparent quadrangle overlays representing the Kardex locations.
- Although much of the information included in Kardex is now out of date, it can be useful for research into past activity in an area of interest. The original Kardex files are housed at the DNR Public Information Center in Fairbanks, and are available for use by the public during business hours.
