These layers were derived from a "union" process of combining numerous polygon coverages using the Environmental Systems Research Institute, Inc. (ESRI) Arc/Info UNION command, and finally calculating coal tonnage in INFO. Net coal thickness values are from 209 data points and represent all coal beds that are more than 1 foot thick. The outside polygon defines the base of the coal-bearing Calico and A-sequences east of 112 degrees of longitude. The northern boundary is delineated by the Paunsaugunt fault and basal outcrops of volcanic rocks of Tertiary age. Purpose: The Nation's coal resources are being assessed by the USGS. A fundamental component of this assessment work is to compile digital geologic and geographic data into a Geographic Information System (GIS). Use of this GIS allowed for the spatial integration of data layers. This resulted in the ability to display, analyze, and query data to answer complex geo-spatial questions concerning coal resource occurrence. As part of this National Coal Assessment, Hettinger and others, chap. T, have completed an assessment of the coal deposits in the Calico and A-sequences of the Straight Cliffs Formation, Kaiparowits Plateau of southern Utah. Their report delineates the distribution of coal and provides estimates of resources in the basin. This data set is intended as a basemap layer for GIS applications at a scale of 1:125,000 or less.

Coal thickness values in hypothetical areas (item REL = 'hypo' for "hypothetical reliability") reflect decreased levels of accuracy for calculated coal thickness based on their distance from a data point. Limitations of the net coal method used to calculate these resources characterize this data set as being a GUIDE TO WHERE THE THICKEST NET COAL AREAS ARE LIKELY TO BE. These data sets serve as an overall picture of the distribution and relative amount of coal. These coverages represent coal distribution based on the available data. These data sets cannot be used for mine planning or to calculate reserves. Additional work is required to determine the mineability and economics of these coal deposits.

The lines were converted from table coordinates to Lambert with the following parameters: Units METERS Spheroid CLARKE1866 Parameters: 1st standard parallel 33 0 0.000 2nd standard parallel 45 0 0.000 central meridian -111 30 0.00 latitude of projection's origin 0 0 0.000 false easting (meters) 0.00000 false northing (meters) 0.00000 The data was later projected to UTM 12 for the coal resource calculations, and then projected to geographic decimal degrees. The Calico and A-sequences contain as many as 30 beds of coal that range from 1 to 59 feet in thickness (Hettinger and others, chap. T) In order to better understand the distribution of these coal beds, in addition to constructing a total coal isopach map, a series of isopach maps were constructed to estimate the net coal in thickness categories of 1.0 - 2.4, 2.5 - 3.4, 3.5 - 7.4, 7.5 - 14.0, 14.1 - 20 and greater than 20 feet. Each isopach map was constructed using coal data listed in appendix 1 of Hettinger and others, chap. T. A value of "zero" was assigned to data points that lack coal within the specified bed thickness category. The item 'THICK' is the result of creating contour output files in the plot routine in EarthVision of Dynamic Graphics, Inc. (DGI). The contour output file was then run through a program (ISMARC) that converts it to an arc input file. The ISMARC program originated with the Illinois State Geological Survey (ILGS), and was provided to us along with amls to further process the data, by Colin Treworgy, Senior Geologist, ILGS. The arc input file is then converted to a polygon coverage in Arc/info by using Colin Treworgy's AML program, "convert-ism". The coverage used to clip the contours in every case was the coverage that defines the base of the Calico sequence boundary. The following is a description of the parameters used in gridding the scattered data files to generate the grids in ISM: Coordinate system: Universal Transverse Mercator (UTM) Units: Meters UTM zone: 12 Ellipsoid: Clarke 1866 Semi-major axis in meters: 6378206.4 Semi-minor axis in meters: 6356583.8 Grid size: 276 by 312 Grid range: 407508,503665 4098129,4203271 Treworgy's aml "convert-ism" assigns a value to the item DEPTH, which is now changed to THICK, by taking one-half the contour interval and adding it to the minimum contour that defines a polygon. For example, if the contour interval is 10, and a polygon is bounded by the 10 and 20 contour lines, then the THICK value assigned to that polygon is 15. To calculate coal resources that can be characterized by a variety of parameters, all data layers (individual coverages) must be combined (UNIONed in Arc/Info) to compute the geometric intersections of all the polygons. When combining two polygon coverages in Arc/Info, specify a fuzzy tolerance that is close to that of the original coverages. union %lyrscov% %thkcov% %outcov% {fuzzy_tolerance} /* note: dropitems (%lyrscov% and %thkcov% # and -id) /* check outcover in arcedit for extraneous polys that may be created /* from computing the geometric intersection of two polygon /* coverages (ie: sel cnty eq ' ').

It was created by subtracting the grid of the surface representing the elevation on the top of the Calico sequence boundary from the grid representing the earth's surface. To determine the grid of the earth's surface we used the 1:250,000-scale Digital Elevation Model (DEM) from the Escalante-west quadrangle. The original DEM was read into Dynamic Graphics, Inc. (DGI) Earth Vision. The grid spacing was too fine for our purpose so we used the formula processing capabilities within Earth Vision to coarsen the grid spacing to the same number of columns and rows that were used for all the other grids. The coverage, overb, is the resultant grid produced by subtracting the grid for the structure of the Calico sequence boundary from the coarsened DEM grid. The original info item that contained overburden thickness information was DEPTH. The item name was changed to OVERB and the character strings within OVERB represent overburden categories in thousands of feet as follows: 0-1 = 0-1000 ft 1-2 = 1000 - 2000 ft 2-3 = 2000 - 3000 ft 3-6 = 3000 - 6000 ft 6 = >6000 ft -99 = internal polygons where overburden is 0 SURF (in kai_tfin and kaintfin) Bureau of Land Management Land status Statewide Utah land ownership coverage for Gap Analysis This is the item that assigns a Bureau of Land Management (BLM) land status category to each polygon. The info item named SURF (for surface management status) contains the land status in character strings as follows: BLM = Bureau of Land Management FS = Forest Service NPS = National Park Service NREC = National Recreation Area STATE PRIVATE WATER Land ownership boundaries covering the entire State of Utah were manually digitized from Bureau of Land Management (BLM) 1:100,000-scale paper maps for the Utah Geographic Approach to Planning Analysis Project (GAP) in 1993. That work included digitizing additional land ownership categories such as wilderness areas, wildlife reserves and Indian reservations derived from the U.S. Forest Service, Utah Division of Wildlife Resources, Bureau of Indian Affairs, and the U.S. Geological Survey. All maps used were 1:100,000. The U.S. Geological Survey received permission to use this data from the Utah Cooperative Fish and Wildlife Research Unit, Utah State University, Logan, UT in 1997. This information is not accurate for legal boundary, or navigation purposes. Later, land and mineral exchanges took place in Utah after the Grand Staircase-Escalante National Monument was created by Presidential Proclamation. In 1999, the updated data were provided by the Utah School and Institutional Trust Lands Administration (SITLA), and we incorporated those land and mineral ownership changes into the data sets kai_tfin and kaintfin. COAL_OWN (in kai_tfin and kaintfin) coal ownership (Federal or non-Federal) PLSS from Utah Trust Lands, INFO file from former USBM, and BLM 1:100,000- scale Maps This is the item that categorizes coal ownership based on the work done by the former U.S. Bureau of Mines (USBM) for their special report: Availability of Federally Owned Minerals for Exploration and Development in Western States: Utah, 1988. The method used by USBM to generate subsurface mineral management status was to generalize to the section level - a whole section defined as being whatever the management status is for 50% or more of that section. Additional information was added based on BLM 1:100,000-scale maps. The info item named COAL_OWN contains information in character strings as follows: fed = Federal coal nonfed = nonfederal coal Later, land and mineral exchanges took place in Utah after the Grand Staircase-Escalante National Monument was created by Presidential Proclamation. In 1999, the updated data were provided by the Utah School and Institutional Trust Lands Administration (SITLA), and we incorporated those land and mineral ownership changes into the data sets kai_tfin and kaintfin. TR township and range PLSS from Utah Trust Lands REL reliability (either identified or hypothetical) Computed USGS-GD-Central Energy Resources Team This is the item that assigns a category of either identified (within three miles of a data point) or hypothetical (greater than three miles from a data point). The ARC/INFO BUFFER command was used to create the reliability circles. The info item named REL contains the reliability information in character strings as follows: iden = identified hypo = hypothetical hole = internal polygons where no coal exists DIP inclination of coal-bearing strata within the Kaiparowits Plateau This is the item that categorizes coal-bearing strata based on ranges of stratal dip. The info item named DIP contains the dip range information in character strings as follows: 0-6 = 0 to 6 deg dip 6-12 = 6 to 12 deg dip 12-25 = 12 to 25 deg dip gt25 = greater than 25 deg dip The range-of-dip was compiled at 1:125,000-scale from structure contour lines and dip measurements shown on 1:24,000-scale published geologic maps of the Kaiparowits Plateau. The range of dip map was used to help determine the mineability of the coal resource based on inclination of strata. INT (in kaintfin) coal-bearing interval (either total or partial) This is the item that identifies where the coal-bearing interval is preserved and where it has been partially eroded, reflecting decreased levels of accuracy for calculated resource. The info item named INT contains information in character string as follows: T = total coal-bearing interval P = partial coal-bearing interval THICK (not included in kaintfin) Total coal or net coal thickness, in feet, in the Calico and A-sequences, Kaiparowits Plateau USGS, Central Energy Resources Team FEDCOAL (in kaintfin) Coal Federally Owned?
