Map BG-1 shows the distribution of bedrock formations occurring at the surface or immediately beneath the glacial deposits that commonly conceal much of the bedrock. This 1:500,000-scale map with associated text and figures reveals not only the characteristics and distribution of the state's various bedrock formations, but it also details the many economic mineral commodities, environmental characteristics, and geological hazards occurring in Ohio. Nearly 50 bedrock units or combinations of units are shown statewide and the legend describes the geologic formations and shows their geologic age. A statewide geologic cross section provides a three-dimensional perspective of the geologic framework of Ohio. Geologists, hydrogeologists, engineers, mineral and fossil-fuel producers, geotechnical consultants, land-use planners, educators, government officials, and others interested in various aspects of Ohio's Earth science will benefit from the details illustrated and discussed on this new map.
