Abstract
In 1986, the Minnesota Geological Survey (MGS) continued a program of scientific test drilling for the purpose of acquiring a better understanding of the Precambrian bedrock of Minnesota. The work was undertaken as part of Minnesota's contribution to CUSMAP projects of the U.S. Geological Survey (USGS) in the International Falls and Roseau 10 x 20 quadrangles. The acronym CUSMAP refers to Conterminous United States Mineral Appraisal Program, a cooperative undertaking of the USGS and state geological surveys that, in the case of Minnesota, involves federal funding of high-resolution aeromagnetic surveys and state funding of follow-up test drilling and limited geologic mapping. A secondary objective of the drilling program has been the acquisition of subsurface data on the stratigraphy, lithology, and thickness of the Quaternary surficial deposits which overlie the Precambrian bedrock. A reconnaissance map of the surficial deposits in the Roseau 10 x 20 quadrangle (1:250,000) will be published in 1988.
