The polygons are subdivided into 2 categories: resource areas inside the outcrop, and areas either too thin, outside the outcrop, or beyond data collection limits. The coal zone must contain at least 14 inches of coal to be a resource. Introduction: This spatial data set of the Lower Kittanning coal bed and known mined areas is one of many Geographic Information System (GIS) products of the National Coal Assessment that is being conducted by the U.S. Geological Survey in cooperation with State geological surveys and other Federal and State agencies. The Lower Kittanning coal bed is an important economic coal in the northern part of the Appalachian Basin. It is of additional importance because it is one of the coal beds that has potential for coalbed methane development within the Allegheny Group throughout most of the Appalachian foreland basin in Ohio, Pennsylvania, West Virginia, and Maryland. This file is the digital compilation of numerous published and unpublished geologic surveys and depicts the area of occurrence of the Lower Kittanning coal bed and its known mined areas. The coal bed was first mined in southwestern Pennsylvania in the early 19th century but substantial mining did not occur until the advent of the rail lines and canals that were built in the mid-19th century. The Lower Kittanning, which produced nearly 20 million tons of coal in 1996, remains the 7th largest-producing coal bed in the nation and the second largest-producing coal bed in the northern Appalachian region (EIA,1997). The coal is generally low to medium in ash yield and sulfur content, and is a medium- to high-volatile steam and coking coal that is mined by both underground and surface mining methods. The Lower Kittanning coal bed occurs in eastern Ohio, central and northern West Virginia, western Pennsylvania, and western Maryland. Although stratigraphic equivalents to this coal bed may extend into southern West Virginia and eastern Kentucky, correlations are equivocal and do not warrant extrapolation into those areas at this time. The coal bed extent and mined areas will be combined with coal isopach and coal bed structure to calculate original and remaining coal resources. Methods: The areal extent of the Lower Kittanning coal zone was digitized from multiple sources using ArcInfo and Arcedit. The digital maps were edited manually in Arcedit and joined to create a single GIS data set (coverage.) See Source_Information and Process_Step for detailed methodology. In West Virginia, much of the area underlain by the coal zone was digitized from reduced transparencies of 1:24,000 scale working maps from the West Virginia Economical and Geologic Survey. The remainder of West Virginia crop was adapted from old topographically-based, 1:62,500 scale county reports from the West Virginia Economical and Geologic Survey. The western and northern extent of the Lower Kittanning coal zone in Ohio was originally scanned from 99 Ohio Geological Survey 1:24,000 scale maps of bedrock geology. Digital files of Ohio crop and surface mines were later combined with digital files of underground mines from the Ohio Department of Environmental Protection. Ohio Geological Survey supplied this combined data set in an Interactive Graphic Design Software file format (.dgn). In Pennsylvania, maps from a variety of sources were digitized. Where available, published or preliminary county reports of reduced 1;24,000 scale maps were digitized. Old topograhically-based, USGS Bulletins were digitized for Lawrence and Beaver Counties. In and around Clearfield County, crop and mines were digitized from Pennsylvania Bureau of Topographic and Geologic Survey Atlas maps at 1:48,000 scale. The remainder of Pennsylvania crop was interpolated or adapted from either topographic maps using Lower Kittanning bore hole data and strip pits or the 1:500,000 scale State geologic map. In Maryland, the crop was digitized or interpolated from 1:24,000 scale USGS coal investigation maps or working USGS maps at 1:24,000 scale. Purpose: The purpose of PP 1625-C is to release the interpretation of assessment and modeling data for the the top-producing coal beds in the northern and central Appalachian Basin coal region.

Source_Scale_Denominator: 24000 Type_Of_Source_Media: stable-base material Source_Time_Period_Of_Content: Time_Period_Information: Single_Date/Time: Calendar_Date: 1996 Source_Currentness_Reference: Publication Date Source_Citation_Abbreviation: USGS-MD Source_Contribution: These maps were source of MD crop in these 7.5' quadrangles: Avilton (southeast corner), Barton, Bittinger (southeast corner), Cresaptown, Cumberland, Deer Park, Frostburg, Gorman, Keyser, Kitzmiller, Lonaconing, Oakland, Sang Run (parts of southern end), Table Rock and most of Westernport. Process_Step: Process_Description: All maps were manually digitized using ARC/INFO. Lines were attributed for source. Process_Date: 1998-2000 Process_Step: Process_Description: Ohio crop data were converted from dgn file format into ARC/INFO format. Process_Date: 1999-2000 Process_Step: Process_Description: Old topographic-based maps (CLR-A65, CLR-A75, Bulletin-1143-B, Bulletin-1143-A, WV-Lew, WV-Min, WV-Up-Ran) were digitized as needed. The crop was plotted over 7.5' topo maps and adjusted to fit drainage; location very generalized. Lines were attributed for source. Process_Date: 1999-2000 Process_Step Process_Description Elk County and Huntley 7.5 min quadrangle, PA crop was originally interpolated from known outcrop, bore hole data, surface mining and State geology map (PA-TGS-PA) Process_Date: 2000 Process_Step Process_Description Elk County and Huntley 7.5 min quadrangle, PA crop was revised according to written communciation from Clifford H. Dodge and working map (PA-ELK-DODGE) Process_Date: 2000 Process_Step: Process_Description: All of the raw line data were appended. Process_Date: 1999-2000 Process_Step: Process_Description: Clearfield Co., Pa missing crop was pieced together for Hastings and Coalport 7.5' quads. Crop adapted on topo maps to match crop on neighboring maps. Process_Date: 2000 Process_Step: Process_Description: Centre Co., Pa. missing crop for Sandy Ridge 7.5' quad was adapted on topo map to match crop on neighboring maps. Process_Date: 2000 Process_Step: Process_Description: Centre and Clinton Co., Pa crop was adapted from structure data points on topo maps in these 7.5' quads: Snowshoe, Keating, Renova West and Renova East. Location very generalized and 'no data' lines drawn to connect limited crop data. Process_Date: 2000 Process_Step: Process_Description: Fayette Co., Pa source map (PA-TGS-FAY) was incomplete and crop was interpolated in select areas of Lake Lynn, Donegal and Seven Springs 7.5' quadrangles. Crop line was attributed for source. Process_Date: 2000 Process_Step: Process_Description: Bruceton Mills 7.5' quadrangle crop was revised along Pa/WV border using topographic map. Crop line was attributed for source. Process_Date: 2000 Process_Step: Process_Description: Somerset Co., Pa crop was revised along the Westmoreland countyline in Ligonier and Bakersville 7.5' quadrangles using topographic maps. Crop line was attributed for source. Process_Date: 2000 Process_Step: Process_Description: Bedford Co., Pa crop for Fairhope 7.5' quadrangle was interpolated across the county boundary from Somerset. Crop line was attributed for source. Process_Date: 2000 Process_Step: Process_Description: Maryland missing crop was adapted on topographic map to match nearby crop in the south end of Sang Run and along Potomac River in Westernport and Kitzmiller quads. Crop line was attributed for source. Process_Date: 2000 Process_Step: Process_Description: Jefferson Co., Ohio crop along Ohio River was adapted to match topography and crop in WV. Crop line was attributed for source. Process_Date: 2000 Process_Step: Process_Description: Straight lines representing 'Limit of available data' were drawn and attributed for source. Lack of data limited the crop in Lawrence, Beaver, Mercer, Venango, Clearfield, Centre and Clinton counties, Pa. Lack of data limited the crop in Atwater 7.5' quadrangle in Portage County, Ohio. Lack of data limited the crop in Garrett County, Md and in Mineral County, WV. Crop line was attributed for source. Process_Date: 2000 Process_Step: Process_Description: A line representing 'Limit of available data' was drawn to connect the southern extremes of known crop. Smooth arcing line was delimited by Lower Kittanning point data. Crop line was attributed for source. Process_Date: 2000 Process_Step: Process_Description: Coal crop data set was edited to resolve inconsistencies between maps and to incorporate revisions. All lines were checked for correct line attribution. Polygon topology was built and a cleaning function was performed. Polygons were attributed using the codes described within this document.
