The following report is the first volume documenting the radiometric and magnetic data taken during the month of September, 1979, by EG&G geoMetrics in the states of Michigan and Wisconsin in the quadrangles: Alpena, Blind River, Cheboygan, Escanaba, and Sault Marie quadrangles.

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.

A high sensitivity airborne radiometric and magnetic survey of the Rice Like, Iron Mountain, Eau Claire and Green Bay 1:250,000 NMTS Quadrangles within the states of Wisconsin, Michigan, and Minnesota. A total of 10,340 line miles of high sensitivity radiometric and magnetic data were collected within these quadrangles. Traverse lines were flown at a spacing of 3.125 miles in an east/west direction at a 18.375 miles seperation. All data were collected utilizing a fixed wing aircraft and over 3,500 cubic inches of Nal crystal detector. Magnetometer data were collected utilizing a high sensitivity proton magnetometer. Data were recorded digitally at 1.0 second intervals aboard the aircraft. Navigation was performed using both visual and doppler techniques. All data presented in this report as corrected profiles of all radiometric variables, magnetic data, radar and barometric altimeter data, air temperature and airborne bismuth contributions. Radiometric data presented are corrected for Comptron Scatter, altitude dependence and atmospheric Bismuth. These data are also presented on microfiche, and digital magnetic tapes. In addition, anomaly maps and inerpretation maps are presented in relating known geology or soil distribution to the corrected radiometric magnetic data.

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.

This report is one part of the second volume containing data on quadrangles of Michigan and Wisconson. This volume contains the detailed geologic summary, interpretation report, standard deviation maps, pseudo-contour maps, interpretation map, flight line and geologic base map, individual corrected profiles, computer map unit histograms and statistical tables for the Escanaba quadrangle.

A report regarding an airborne radiometric survey of upper Michigan and Parts of Wisconsin

From Introduction: "The lack of comparable and accurate statistics of coal-mine accidents in the united States as a whole led the Bureau of Mines in 1911 to undertake the collection of such data. The mining departments of the leading foreign coal-producing countries have long taken cognizance of the importance of statistics. The bureau feels that in presenting the tables embodied in this report it is offering the and comparable statistics of coal-min accidents for the country as a whole that have ever been published."

The Midwestern Disaster Tax Relief Act of 2008 is intended to assist with the recovery from the severe weather that affected the Midwest during the summer of 2008. The Jobs, Energy, Families, and Disaster Relief Act of 2008 includes some similar provisions, but these are not limited to the Midwest disaster. The disaster relief in the three bills is similar to that provided to assist with the recovery from the 2005 hurricanes and the 2007 Kansas tornadoes. This report broadly discusses the disaster relief provisions in other relevant legislation.

Discussing water samples collected during a reconnaissance study for uranium, and the analysis of the samples.

From introduction: The purpose of this report is to describe the geology of the rocks in the different sedimentary basins in relation to problems of disposal of liquid radioactive wastes in the ground.

From abstract: Results of a reconnaissance geochemical survey of the Iron Mountain Quadrangle, Michigan; Wisconsin are reported. Field and laboratory data are presented for 479 groundwater samples, 369 stream sediment samples, and 389 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 on the magnetic base stations located in Minnesota, Michigan, and Wisconsin. The report evaluates the usefulness of the stations for calibration of certain instruments. This report contains tables, graphs, maps, and illustrations.

A report regarding evaluations done of the Ashland Quadrangle to find favorability for uranium occurrences in the quadrangles geologic environments. "No favorable areas could be identified or delineated on the basis of available data, and it is concluded that geologic environments in the Ashland Quadrangle are unfavorable for uranium."

Report discussing lake-bottom sediment sampling; radon soil gas surveying, and chemical analyses for rock, stream-sediment, ground, spring-water, lake-water, and stream-water samples collected for a report discussing the favorability for uranium occurrences in geologic environments of the Ashland quadrangle of Wisconsin, Michigan, and Minnesota.

From abstract: Detailed knowledge of the geology of the pre-Cambrian rocks of the Lake Superior region has been greatly augmented since the publication of Monograph 52 by the United States Geological Survey in 1911. The authors have attempted in the present report to assemble as much of this new information as possible, and to give the reader a birdseye view of the geology as seen in the light of all studies made there up to the present time. Detailed descriptions are not presented, and the emphasis is placed upon the major problems of correlation. A revised map of the region, with cross sections, accompanies the report, bringing up to date a knowledge of the areal geology of the region, which otherwise could be gained only by consulting some 150 maps contained in almost as many separate local reports, many of which are unpublished.
