Description
During the glacial periods, the melting and freezing of glaciers created sediment layers that now compose the shoreline sediments of Lake Michigan. Fast forward to the present, and the rise and fall of Lake Michigan levels has increased the eroding of the shoreline. This starts with the undercutting of the land which causes the topmost layers to fail and produces landslides[2]. Additionally, mass movements tend to favor locations of interlayered sand and clay[2]. It helps develop perched groundwater systems where weak lacustrine clay/silt fails to support the weight of overlying soil[2]. My research goal is to determine the interlayered sediments in failed bluffs with the use of GPR, a geophysical method for investigating the shallow sub-surface
