Book excerpt: The Ohio Division of Geological Survey (OGS) is mapping the glacial deposits throughout the state of Ohio. One major goal in this effort is to map the three-dimensional glacial geology of the state in order to characterize the extent, vertical succession, and thickness of the glacial materials from the surface down to and including the uppermost bedrock unit. However, many areas in the state are remote and subsurface information on the geology and thickness of the glacial deposits does not exist. The OGS has been using the seismic refraction technique as a cost effective tool to acquire subsurface information in these problem areas.
