During the months of August and September, 1979, geoMetrics, Inc. collected 12,415 line miles of high sensitivity airborne radiometric and magnetic data in adjoining portions of South Dakota and Minnesota over seven 1 by 2 degree NTMS quadrangles (Thief River Falls, Grand Forks, Fargo, Milbank, Watertown, New Ulm, and St. Cloud). All radiometric and magnetic data were fully corrected and interpreted and are presented as eight volumes.

This report discusses aeromagnetic data that was obtained from uranium anomalies discovered in the Milbank quadrangle of South Dakota, North Dakota, and Minnesota.

This report discusses aeromagnetic data that was obtained from uranium anomalies discovered in the Watertown quadrangle of South Dakota and Minnesota.

From introduction: This volume contains information and survey results pertaining specifically to the Hot Springs NTMS 1:250,000 scale Quadrangle, South Dakota, one of a group of 12 such quadrangles in Arizona, Idaho, Montana, New Mexico, South Dakota, and Washington included in an aerial radiometric and magnetic reconnaissance survey. General information concerning the instrumentation and methods used in data acquisition, processing, and interpretation is presented in Volume 1 of this final report.

Appendices containing data on uranium availability to accompany a report on U.S. uranium resources Ekalaka Quadrangle in Montana.

This report is the first volume of a two-part set documenting the results of the analyses of the airborne gamma radiation and total magnetic field survey that was flown for the Lemmon National Topographic Map NL13-9.

This report is the second volume of a two-part set documenting the results of the analyses of the airborne gamma radiation and total magnetic field survey that was flown for the Lemmon National Topographic Map NL13-9. This volume includes the flight line magnetic field, temperature, pressure, altitude data plus magnetic field data as measured at a base station.
