In all developed areas most productive horizons have shows, over large portions of the area. Conversely, most horizons that have shows eventually produce commercially over at least part of the area. In this region shows have been widespread through the Pennsylvanian, Mississippian, and Devonian. Ordovician has been identified at Boundary Butte and tentatively so at Horsefly with shows. Porosity has been poor but of such nature that only slight improvement is necessary in several zones to cause these to be commercially productive. The salt anticlines were growing during Hermosa time with variations in conditions of deposition and character of beds, making these features attractive for exploration. Continued exploration is confidently expected to discover oil and gas fields of importance over a vast region.
