공공데이터포털
This is a point file that contains data for coal and other stratigraphic horizons in in the Calico and A-sequences of the Straight Cliffs Formation (Upper Cretaceous) east of 112 degrees of longitude in the Kaiparowits Plateau. The item map# is the number of the data point on the index map (Figure A, Plate 1). The map# that refers to a record in the data table (Appendix 1) in Hettinger and others, chap. T. Buffers were drawn at a three-mile distance from data points in this coverage to create the reliability coverage.
