This directory is a revision of a portion of a final report prepared for the U.S. Bureau of Mines for grant #G0264002 entitled "Manganese-bearing ores of the Cuyuna iron range, east-central Minnesota, Phase 1". This work arose from the need for a compilation of basic geologic and mining information on the Cuyuna range. This work is intended to compliment the "Selected bibliography of Cuyuna range geology, mining and metallurgy", Minnesota Geological Survey, Inf. Circ. 12, and "Manganese resources of the Cuyuna range, east-central Minnesota: a preliminary appraisal", Minnesota Geological Survey, Rep. Invest. 18.
