New York Glacial Surveys

Laura Sherrod - 2016

Three dimensional imaging of glacial deposits has become a very important way to expand our understanding of the geologic history of locations such as Michigan and New York.  Through geophysical surveys such as Resistivity, images of the subsurface can be produced to show the three dimensional nature of glacial structures and thus make detailed interpretations of the processes at work during previous glacial advances and retreats.  Dr. Laura Sherrod and Kutztown University undergraduate students Austin Keller, Bojan Milinic, Sarah Moriarty, Ashley Richardson, and David Vales joined Dr. Andrew Kozlowski and Dr. Brian Bird of the New York State Geologic Mapping Program in the summer of 2016. Two field sites were investigated over the course of the geophysical field work: a bedrock valley buried in glacial sediments and a hops farm.

Austin Keller, Ashley Richardson, David Vales, Bojan Milinic, and Sarah Moriarty set up the resistivity survey

The bedrock valley is located below farmed fields adjacent to a ravine through the glacial sediments.  Exposures at the ravine reveal interesting soft-sediment deformation features.  The purpose of the geophysical surveys at this location was to map the glacial stratigraphy across the site and, if possible, to identify the depth to bedrock. 

The nearby hops farm is also adjacent to a ravine through glacial sediments.  This ravine reveals potential sources of spring water, which could benefit the agricultural productivity of the hops.  The purpose of the geophysical surveys at this location was to map the potential spring source with the intent of installing a well to access this water resource
