Known mineral deposit areas and mining claims in eight western states.
Abstract Book, U.S. Department of the Interior Conference on the Environment and Safety, April 24-28, 1995. Washington, DC: U.S. Bureau of Mines, 1995 Apr; :55
Past and present mineral-development activity are represented spatially. Past activity is represented by Known Mi neral Deposit Areas (KMDAs). KMDAs were developed as part of the Bureau's 10-year "Inventory of Land Use Restraints" project. Present activity is represented by existing mining claims, as recorded in the Bureau of Land Management's Mining Claim Recordation Database. Claim data is attached to the Public Land Survey for each of eight states - California, Idaho, Montana, Nevada, Oregon, Utah, Washington, and Wyoming. KMDAs with open claims identify areas being re-explored; open claims outside KMDAs may represent new discoveries. Area with abandoned claims may be candidates for remediation of environmental concerns or areas of past economic interest (i.e., uranium).
