[en] The Watertown 1:250,000 scale quadrangle of South Dakota/Minnesota is everywhere covered by variable thicknesses of Wisconsin age glacial deposits (drift). Bedrock is nowhere exposed, but is thought to be composed of primarily Cretaceous sediments. There are no known uranium deposits (or occurrences) within the quadrangle. Sixty-seven (67) groups of uranium samples were defined as anomalies and are discussed in the report. None of them are considered significant
