 map area. Traverse lines were flown in an east-west direction at a line spacing of six (0) miles. Tie lines were flown north-south approximately twenty-four (00) miles apart. A total of 00,000 line miles of geophysical data were acquired, compiled, and interpreted during the survey, of which 0000 line miles are in this quadrangle. The purpose of this study is to acquire and compile geologic and other information with which to assess the magnitude and distribution of uranium resources and to determine areas favorable for the occurrence of uranium in the United States  An airborne high sensitivity gamma-rayspectrometer and magnetometer survey was conducted over eleven (00) 0 0 x 0 0 NTMS quadrangles located in the states of Minnesota and Wisconsin and seven (0) 0 0 x 0 0 NTMS quadrangles in North and South Dakota. The quadrangles located within the North and South Dakota survey area include Devil's Lake, New Rockford, Jamestown, Aberdeen, Huron, Mitchell, and Sioux Falls.
