Aerial Gamma Ray and Magnetic Survey, Final Report. Volume 1: Rice Lake Quadrangle (Wisconsin), Iron Mountain Quadrangle (Wisconsin/Michigan), Eau Claire Quadrangle (Wisconsin/Minnesota), and Green Bay Quadrangle (Wisconsin)

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.

Pre-Cambrian Rocks of the Lake Superior Region: A Review of Newly Discovered Geologic Features, with a Revised Geologic Map (open access)

Pre-Cambrian Rocks of the Lake Superior Region: A Review of Newly Discovered Geologic Features, with a Revised Geologic Map

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.

National Uranium Resource Evaluation: Eau Claire Quadrangle, Wisconsin and Minnesota

Purpose and scope: The Eau Claire Quadrangle, Wisconsin and Minnesota, was evaluated to identify geologic units and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. All geologic environments to a depth of 1500 m (5,000 ft) were evaluated by means of surface investigations and available subsurface data. Each environment was categorized as favorable, unfavorable, or unevaluated for uranium deposits based on recognition criteria contained in the study of significant uranium districts worldwide (Mickle and Mathews, eds., 1978). Evaluation of the Eau Claire Quadrangle was conducted by Golder Associates, Inc., under subcontract to Bendix Field Engineering Corporation (BFEC), for the National Uranium Resource Evaluation (NURE) program, managed by the Grand Junction Office of the U.S. Department of Energy (DOE). The evaluation program began February 1, 1978, and ended February 1, 1980. Time spent by Golder personnel on literature search, field work, evaluation of data, and preparation of the final report totaled approximately 3.5 man-years.

Plan of Study for the Northern Midwest Regional Aquifer-System Analysis

From abstract: Sedimentary rocks of Cambrian and Ordovician age form a major aquifer system in most of Wisconsin and Iowa, northern Illinois, northwestern Indiana, southeastern Minnesota, and northern Missouri. Many metropolitan areas depend on the aquifer for all or part of their water supplies. Declines in potentiometric head have been large in the most heavily pumped areas, most notably Chicago, Milwaukee-Waukesha, Minneapolis-St. Paul, and Des Moines.

Disaster Tax Relief for the Midwest (open access)

Disaster Tax Relief for the Midwest

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.
