On the basis of fieldwork and drilling completed in the Fall of 1980, several zones of intertonguing between the Star Point Sandstone and the overlying Blackhawk Formation have been identified in the northern part of the Wasatch Plateau, Carbon County, Utah (sheet 1). As a result of this work, correlations of important coal beds have been revised. The U.S. Geological Survey drilled a total of 12 holes in the area, from the west side of Pleasant Valley, near Slaughterhouse Canyon, to the eastern part of the Beaver Creek drainage (sheet 1) (Blanchard and others, 1976; U.S. Geological Survey, 1980). In addition, several detailed sections were measured from Spring Canyon near Price, Utah (sheet 1), to Slaughterhouse Canyon.
