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.

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 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.

This report follows the study of uranium and thorium potential of the Precambrian rocks of northern Wisconsin and the western half of the Upper Peninsula of Michigan.

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.

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.

Data collected as part of a report on the Portland Maine NTMS area including laboratory data on well, spring, and stream waters and stream sediments as well as field data.

"Sweet clover is now grown successfully on many farms in the corn belt, both in rotation and as a catch crop to be plowed under. It has proved excellent for hay and pasture, and is unequaled by any other legume for soil improvement. Sweet clover may be used to good advantage for silage, and on some farms, with proper management, it is a profitable seed crop. Mixed with bluegrass, it makes a pasture of nearly double the carrying capacity of bluegrass alone. The object of this bulletin is to present details of management and of the more important farm practices followed on some of the successful corn-belt farms on which sweet clover is grown as one of the principal crops of the rotation. Cropping systems are outlined for farms of different types, and special attention is called to the three essentials of success in growing the crop -- lime, inoculation, and scarified seed." -- p. 2

The following report discusses the study of radioelements in precambrian rock samples taken from the upper peninsula of Michigan and northern Wisconsin.

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: 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.

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.

"This appendix contains phase arrival information for local and near-regional events which have been well recorded by the Anna Seismic Network." (p. B1)

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.

This report discusses the roundheaded apple-tree borer, an insect in the eastern and midwestern United States that, in its larval stage, destroys the bark and wood of apple trees. Several methods of control are discussed, including worming, paints and washes, and sprays.Apple-tree borers.
