This is a polygon coverage of the inclination of strata within theKaiparowits Plateau. Inclinations of strata are attributed incategories that range from 0 - 6, 6 - 12, 12 - 25, and > 25degrees. The range-of-dip was compiled at 1:125,000-scale fromstructure contour lines and from dip measurements on 1:24,000-scalepublished geologic maps of the Kaiparowits Plateau. These geologicmaps are referenced in figure 2 of Hettinger and others (1996).The outside polygon defines the base of the coal-bearing John HenryMember of the Straight Cliffs Formation (Upper Cretaceous) east of112 degrees of longitude. The northern boundary is delineated bythe Paunsaugunt fault and volcanic rocks of Tertiary age. The areawithin this polygon includes parts of the coal-bearing John HenryMember where the entire section may not be represented due toerosion.
