dc.description.abstractThe Central Great Lakes Geologic Mapping Coalition (now the Great Lakes Geologic Mapping Coalition or GLGMC) was formed in the late 1990s between the USGS and a network of state geological surveys which border the Great Lakes. The GLGMC was tasked with creating innovative three-dimensional (3-D) mapping, models, and other means for displaying the complex near-surface geology common to these states. These 3-D products, along with associated databases could be used to assist decision-makers on projects including geologic hazards, groundwater, mineral industries, and land usage. The Milan 7.5-minute quadrangle (Erie and Huron Counties) in north-central Ohio was chosen as one of the pilot projects for this program. The Milan quadrangle is transitional in origin and includes glacio-lacustrine, shoreline, alluvial, and glacial processes making for extremely complex series of depositional environments. A number of data sources including water well log data, engineering boring logs, NRCS soil surveys, theses, and prior reports were used to compile a series of maps using ESRI ARC-GIS tools. Each identified geologic unit or zone was identified and displayed as a discrete body. The origin, composition, and geomorphology of each body are thoroughly discussed herein. The entire sequence of overlapping units is represented as a geologic map and cross-section at scale of 1:24,000. The geologic map is accompanied by both a bedrock topography and drift thickness maps. A thick, elongated body of sand in the center of the mapping area was identified as a potentially important economic resource. A number of derivative maps were produced that include aquifer potential, aggregate potential, aquifer recharge, landfill suitability, and suitability for excavation and construction.en
