Fracture History of the Divide Creek and Wolf Creek Anticlines and Its Relationto Laramide Basin-Margin Tectonism, Southern Piceance Basin, Northwestern Colorado (Chapter Z)

The Divide Creek and Wolf Creek anticlines are two gentle, north-northwest-trending, gas-producing intrabasin folds near the eastern margin of the Piceance basin of northwestern Colorado. Both folds developed above a decollement on the basinward side of a large, basement-involved thrust wedge that resulted from
