This is a point coverage that contains data for coal and otherstratigraphic horizons in the John Henry Member of the StraightCliffs Formation (Upper Cretaceous) east of 112 degrees oflongitude in the Kaiparowits Plateau. The item map# is the numberon the index map (Figure A, Plate 1) that refers to a record in adata table (Appendix 1) in Hettinger and others (1996). Bufferswere drawn at a three-mile distance from data points in thiscoverage to create the reliability coverage. This coverage alsoincludes arcs representing lines of cross section shown in Figs. B,C, D and E, Plate 1 (Hettinger and others, 1996).

The U.S. Geological Survey (USGS) is undertaking a five year effortto identify and characterize coal beds and coal zones that couldprovide the fuel for the Nation's coal-derived energy during thefirst quarter of the 21st century. As part of this National CoalAssessment, Hettinger and others (1996) have completed anassessment of the coal deposits in the John Henry Member of theStraight Cliffs Formation, Kaiparowits Plateau of southern Utah.Their report delineates the distribution of coal and providesestimates of resources in the basin.It also serves as a basis for future efforts to assess coalresources and determine availability and recoverability. Afundamental component of their work was the digital geologic andgeographic data compiled in a Geographic Information System (GIS).Use of this GIS allowed for the spatial integration of data layers,and resulted in the ability to display, analyze, and query data andproduce information that are useful for land-use planning and toanswer complex geo-spatial questions concerning coal resourceoccurrence.This coverage (kaipcoal) provides the tabular data on coal in theJohn Henry Member of the Straight Cliffs Formation (UpperCretaceous) east of 112 degrees of longitude in the KaiparowitsPlateau. The point locations are intended for GIS application at ascale of 1:24,000 or less, for example 1:100,000).
