This report explains what is meant by restoration, the Corps' restoration plan, and some of the issues in the debate over federal investment in this restoration.

First volume of a report documenting a high-sensitivity airborne radiometric and magnetic survey of four quadrangles in Wisconsin, Minnesota, and Michigan including documentation about data collection and analysis.

Second volume of a report documenting a high-sensitivity airborne radiometric and magnetic survey of the Ashland quadrangle including maps documenting geophysical and geochemical data.

From abstract: Results of a reconnaissance geochemical survey of the Eau Claire Quadrangle, Wisconsin; Minnesota are reported. Field and laboratory data are presented for 565 groundwater samples, 680 stream sediment samples, and 667 stream water samples. Statistical and areal distributions of uranium and other possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.

Report issued by the U.S. Bureau of Mines discussing the iron-ore mining accident experience in the Lake Superior District. Frequency and severity rates of accidents between 1940 and 1943 are presented. This report includes tables.

"Results of a reconnaissance geochemical survey of the Watertown Quadrangle are reported. Field and laboratory data are presented for 711 groundwater and 603 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. a generalized geologic map of the survey is provided and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed."
