Dakota sandstone
Dakota Sandstone and Purgatoire Formation, due to generally gentle dip, form broad outcrop areas (fig. 2) in contrast to the more common hogback-shaped outcrops found along the mountain flanks where the strata dip steeply. Scott and others (1978) and Stout (1958) have mapped several high-angle faults whichAlthough sandstone porosity varies over a limited range and averages near 36%, total sandstone thickness ranges from less than 10% to more than 90% of the Dakota Formation thickness in Kansas. Furthermore, the amount of water released from the surrounding mudstones to the sandstones as leakage due to pumping is uncertain (Neuzil, 2002).Dinosaur Ridge is a segment of the Dakota Hogback in the Morrison Fossil Area National Natural Landmark located in Jefferson County, Colorado, near the town of Morrison and just west of Denver . The Dinosaur Ridge area is one of the world's most famous dinosaur fossil localities. [citation needed] In 1877, fossil excavation began at Dinosaur ...

The Dakota Sandstone and the Cheyenne Sandstone Member of the Purgatoire Formation are the principal formations in Otero and Crowley Counties known to contain soft water.

The Dakota sandstone shows the least loss of the six samples undergoing the magnesium sulfate test. The average percent loss on the Los Angeles abrasion test is high, and is exceeded only by tests on the Fort Hays chalky limestone and the Fort Riley dolomite, but only six of the rocks were subjected to this test.Dakota Dakota 584 8,851 Frontier Dakota-Lakota 13 0 1,092 Niobrara Niobrara Dakota 0 0 Niobrara Shannon Sandstone.-Johnny Moore Mtn.

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.

In scattered places in the United States, carbonate rocks are interbedded with almost equal amounts of water-yielding sandstone. In most places where these two rock types are interbedded, the carbonate rocks yield much more water than the sandstone. Sources/Usage: Public Domain.
The Entrada Sandstone forms rounded, orange hills near the valley Outward from the Paleozoic beds is the Spearfish Formation (Triassic) that forms the Red Valley (or Racetrack) that entirely rims the edges of the Black Hills. Next, the Dakota Sandstone (Cretaceous) forms a prominent hogback encircling the uplift. Late Mesozoic and Tertiary beds comprise the plains beyond the hogback.
