Item Imagining Scientific Realities Deep Underground: Utilizing Knowledge and 3-D Geological Modeling, Fundamental Tenets of The University of Minnesota’s Proposed Institute for Underground Science and Soudan Dusel(University of Minnesota Duluth, 2007-03) Peterson, Dean MThe ultimate goal of scientific research is to enhance knowledge, thus allowing one (or all) to imagine reality. The most renowned physicists, e.g., Nicholas Copernicus, Galileo Galilei, Isaac Newton, Max Planck, Albert Einstein, and Niels Bohr, and geologists, e.g., Nicholas Steno, William Smith, Charles Lyell, Louis Agassiz, Alfred Wegener, Harry Hess, and J. Tuzo Wilson, all used their individual imaginations to open the door to new scientific realities that we as a society now realize. Quite possibly the greatest scientific reality ever imagined is Charles Darwin’s theory of Natural Selection (“On the Origin of Species,” published in 1859). The National Science Foundation’s (NSF) goal of scientific research at a U.S. Deep Underground Science and Engineering Laboratory (DUSEL) is to enhance our collective knowledge of physics, geology, biology, and engineering through dedicated research in a deep underground setting. This short report highlights some of the geological features and their relationships to future science opportunities associated with the University of Minnesota’s most recent (January 9, 2007) DUSEL proposal to the NSF (Marshak et al., 2007). In this proposal, the University plans to develop the Institute for Underground Science (IUS) at the University of Minnesota and expand the current Soudan Underground Laboratory down to a depth of 1500m, i.e., 4125 meters of water equivalent (MWE) immediately southeast of its current location. The IUS would be a widely-collaborative, multidisciplinary institute with a mission to facilitate a coherent theoretical and experimental program in underground science and technology. Previous University of Minnesota DUSEL proposals (Marshak et al., 2003, 2005) have outlined the opportunities for deep underground science at the Soudan Mine near Tower, Minnesota, though an interdisciplinary science vision was not yet developed in the 2003 proposal, and the location of a Soudan DUSEL in the 2005 proposal was approximately one mile east (and thus largely hosted within a different stratigraphic sequence of rocks) than the recently proposed site at Soudan.Item MnDOT Highway 169 2015 Drilling Project(University of Minnesota Duluth, 2017-06) Heine, John J; Patelke, Marsha Meinders; Buschette, Michael; Leu, Adam; Maly, Craig C; Gordee, Sarah M; Chlebecek, Sara; Lee, Aubrey; Post, Sara PThe Natural Resources Research Institute (NRRI) Economic Geology Group was contracted by the Minnesota Department of Transportation (MnDOT) [Project Number 0005269] to provide onsite drilling supervision, core logging and sampling, and geochemical studies related to proposed construction along Highway 169 east of Soudan, Minnesota. The goal of this project was to provide MnDOT the data required to produce a mitigation plan for the Highway 169 Eagles Nest project. MnDOT, working with the Minnesota Department of Natural Resources (DNR) and Golder Associates, was responsible for developing the guidelines for this work with the help of the Highway 169 Technical Working Group (Minnesota Pollution Control Agency, Minnesota Department of Health, US Corps of Engineers, Environmental Protection Agency, and NRRI). Golder Associates (Seattle, WA office) was responsible for developing the mitigation plan for bedrock roadcuts along the reroute. This work was a continuation of the studies by Severson and Heine (2010, 2012) and Heine (2015) which examined the bedrock outcrops along three proposed Highway 169 reroutes and alternatives. Severson and Heine (2012) concluded that drilling would be needed in the potential bedrock roadcuts along the reroute corridor to fully characterize the geology as required in the mitigation plan.
