Paleocurrents and depositional environments of the Dakota Group, San Miguel and Mora Counties, New Mexico
— Craig R. Bejnar and R. H. Lessard

The Dakota Group is a widespread and well known rock stratigraphic unit in the Rocky Mountain region and has gained recognition throughout the area for its reservoir characteristics. The recent discovery of a shallow methane gas field in the Dakota Group near Wagon Mound, New Mexico, has reactivated a commercial interest in this unit as a potential hydrocarbon reservoir in the Las Vegas sub-basin as well as in the Raton basin and adjacent areas. Although many workers have referred to the Dakota Group on the eastern side of the Rocky Mountains, the only detailed stratigraphic studies of the unit are by Jacka and Brand (1972) and Asquith and Gilbert (this Guidebook). This paper supplements these studies with additional information on the geology of the Dakota Group in San Miguel and Mora Counties.
