The upper member of the formation consists of similar sandstones, usually not so thick, less massive, and with less conglomerate. Between the sandstone members is a series of interbedded dark shales and buff sandstones, with here and there thin beds of coal. The thickness of the whole "Dakota" series is about 200 feet. Gypsum measures.The Cubero Sandstone Tongue of the Dakota Sandstone is composed mostly of very fine to fine-grained sandstone that is commonly silty and contains locally abundant carbonaceous debris. It tends to form a resistant cliff between underlying shale units in the Oak Canyon Member of the Dakota Sandstone and overlying marine shales of the Mancos Shale.But on the edge of the foothills, where the layers were scraped and pushed only slightly upward, the western edge of their remnant still stands at about a 45 degree angle - the Dakota Ridge. There is an interesting reason that the ridge survived many years of exposure to rain, snow, ice, and wind: The top layer is a hard sandstone. the Dakota ...The Dakota Sandstone is 0 to 38 m (125 ft) thick, of Cenomanian age, and records multiple cycles of sediment accumulation.

In most of the area that it occupies it is covered with thick deposits of younger formations, chiefly shale, that confine the water in the sandstone under considerable pressure. Where the topography is favorable, as it is in the Ellendale-Jamestown area in southeastern North Dakota, wellsThe basal unit of the overlying Dakota Formation, the Encinal Canyon Sandstone is a thin-bedded, cross-bedded, gold-colored sandstone interbedded with black shale and carbonaceous beds. The Oak Canyon Member is a shale with plant debris fossils interbedded with a few thin bioturbated sandstone beds. Sequence of forms developed by continued sandstone concretion growth. All four types, with many intermediate shapes, are present in south-western North Dakota. From Parsons (1980). Table I simply illustrates the wide variety of concretions and nodules found in one geologic unit in southwesternmost North Dakota.

Over time, circulating water deposited a limey cement between the sand grains, creating harder bodies of sandstone called concretions. Concretions are often spherical.The Entrada Sandstone forms rounded, orange hills near the valley floor. The Curtis and Summerville layers are submerged, but soft, rounded hills of bentonite in the Morrison Formation appear. A ridge of Dakota Sandstone, resistant to erosion, also stands out from the valley floor.The Dakota aquifer system consists of sandstone bodies deposited about 100 million years ago during the Cretaceous Period. These formations are found at the surface and in the subsurface in most of the western two-thirds of Kansas. Kansans, and others in the Great Plains region, have used the Dakota as a source of water for more than a century.
