Sangre de Cristo Mountains: East flank Culebra range thrust fault and Raton basin prospects, Colorado
Drilling in the Stonewall area west of Trinidad confirms seismic evidence of major thrust faulting displacing the surface complex a minimum of 2.5 km (1.5 mi) eastward over the west flank of the Raton basin. There is no direct evidence of this master fault where it apparently intersects the surface in the poorly exposed Pierre Shale section east of the Dakota stonewall. This mountain-to-basin relationship has been established in some of the frontal ranges to the north, but it had not been proven in this part of the Sangre de Cristo. Although commercial hydrocarbons were not found in this test, the structural information provides encouragement for exploration of hidden traps in other sectors of the mountain front.
