The University of Minnesota School of Physics and Astronomy is having a laboratory constructed 713 m below ground at the Tower-Soudan State Park in Minnesota. In addition to the planned usage of the laboratory cavern, noteworthy aspects of the project are: its depth, the relatively weak, highly schistose rock, and the use of existing excavations to evaluate ground conditions and rock response. The geologic conditions are proving as anticipated from the field investigation plan. Support needs are within the range expected in design and are being met with rockbolting and shotcrete designs.
