Description: This data layer contains the geologic structures that are represented as lines on the 1:24,000-scale bedrock-geology maps. Examples include faults, anticlines, and synclines. The lines were originally derived from the 1:24,000-scale bedrock-geology maps, which were created between the mid 1960's through 1997. Detailed mapping at 1:24,000 scale was performed in Ohio from the 1960's to the 1980's. During that time period, 37 7.5-minute quadrangles were mapped in detail. The bedrock-geology mapping program was initiated at the Ohio Division of Geological Survey in 1991 to perform reconnaissance geologic mapping at 1:24,000 scale. The reconnaissance and detailed geologic mapping have been combined together into this GIS dataset. There will be edge-matching issues between the reconnaissance and detailed geologic maps.

Description: This data layer contains the 1:24,000-scale bedrock-geology polygons for Ohio.

Description: This data layer contains the 1:500,000-scale bedrock-geology polygons for Ohio. The polygons were originally derived from the 1:24,000-scale bedrock-geology maps, that were created between 1989 through 1998. The bedrock-geology mapping program was initiated in the mid-1980s to perform detailed, 1:24,000-scale bedrock-geology maps. In 1991, the mapping approach was amended to a reconnaissance mapping methodology, but retaining the 1:24,000 scale. Both detail and reconnaissance bedrock-geologic maps were used as the basic information to compile the 1:500,000-scale, Bedrock Geologic Map of Ohio.

Description: This dataset shows the glacial boundary in Ohio.Since the publication of the Glacial map of Ohio (Goldthwait, White, and Forsyth, 1961, U.S. Geological Survey Miscellaneous Geologic Investigations Map I-316), many workers have continued efforts to decipher the Quaternary history, geomorphology, and deposits of Ohio. This map of the Quaternary geology of Ohio attempts to consolidate this improved understanding of Quaternary geology in a uniform format for the entire state.Compilation ws begun by the late Dr. Richard P. Goldthwait, to whom this map is dedicated. Additional revisions and compilation of a series of 1:250,000-scale open-file maps (Ohio Division of Geological Survey Open-File Maps 291-300, 1993) were completed by staff of the Ohio Geological Survey, prior to preparation of this map. The individual maps used to compile this map differ widely in age, scope, and detail. Many areas of complex geology have been simplified to fit the scale and map units of this map. Refer to the data sources listed below for available maps that have more detail at a larger scale. The geological units on this map are grouped by age, depositional process, (water-deposited, ice-deposited, etc.), and geomorphic occurance (ground moraine, end moraine, hummocky moraine, etc.). For example, the most common unit in northeastern Ohio is G4, a Late Wisconsinan-age clayey till (Hiram Till) depositied as ground moraine.

Description: This is a map of the base elevation of the Pittsburgh (No.8) Coal Bed created by the Ohio Geological Survey in 2015. This raster was created with a point GIS file containing Pittsburgh base elevations and thicknesses. The public data points file that this map was derived from is called "Public_Pittsburgh_Points". For more information please see the Ohio Geological Survey Publication “Evaluation Of Available Resources Of The Pittsburgh (No. 8) Coal Bed In Ohio”. Raster cell values represent the base elevation of the coal bed in feet. This raster was created with Natural Neighbor interpolation. Cell size is 100ft.
