Minnesota River Valley 1990 Wide-angle Experiment

In the summer of 1990, the University of Wyoming conducted a wide-angle reflection/refraction experiment along the Minnesota River Valley. The goal of the experiment was to image crustal structure and determine the velocity of the crust beneath the Archean terrane. A total of 180 SGRs and 33 6-channel REF TEK instruments were deployed in a linear array with a spacing of 100 meters. Seven blasts from four differend quarries provided the seismic energy.
