Dakota sandstone.
Sandstone in the Dakota Formation of Ottawa County is light gray, very pale and dark yellowish orange, and reddish brown. It occurs as beds less than 1 foot thick and as massive lenses as much as 60 feet thick and extending as far as 6 miles laterally. Sandstone lenses and layers locally occupy scour channels in underlying claystone and mudstone.
The Dakota Formation, a widespread sandstone that crops out on hillsides and can be seen in road cuts in central Kansas, formed from sand deposited on or near the Cretaceous seas that covered much of Kansas 80 million years ago. Historically, Dakota Sandstone was used in the construction of buildings and bridges in central Kansas. Oddly shaped ...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.About 100 million years ago, the sea reached the Mesa Verde area and deposit ed the Dakota Sandstone. Initi ally, sand was deposited in a very shallow area of the sea near the beach. The sand was compacted and cemented into sandstone. These rocks form the erosion resistant base of the Montezuma Valley below Mesa Verde, around the city of Cortez.The deeply buried Dakota Sandstone Aquifer showed an average increase of 1.3 feet. Recharge impacts to the Dakota Sandstone Aquifer can take several years to be reflected in the water levels. The 2023 spring water levels, although lower than recent years, remain above the recorded lowest spring levels prior to the drought conditions of 2012.
The Dakota aquifer system is the most geographically extensive of all the aquifer systems in the upper 2,000 ft (600 m) of the subsurface of western and central Kansas. The geologic units that form the Dakota aquifer in Kansas are the Dakota Formation, the Kiowa Formation, and the Cheyenne Sandstone (table 1).The Newcastle Sandstone is only a few tens of feet thick where it crops out on the flanks of the Black Hills Uplift, but its subsurface equivalent, the Dakota Sandstone, is more than 400 feet thick in southeastern South Dakota. The Newcastle (or Dakota) Sandstone is absent in much of North Dakota, and the thickness of the Muddy Sandstone, which ...

The sand grains are medium-sized, ranging from 1/4 to 2 mm across, and can be rounded to angular. Sandstone is usually brownish, tan, reddish, gray, or off-white, but can be almost any color depending on its mineralogy. Sandstone.The nearby fault zone contains uraniniferous asphalt.

Dakota sandstone is made up of a number of components, including beach and lagoonal sandstones, shale, and conglomeratic (large-grained) sandstone layers deposited in the area as a shallow sea advanced through New Mexico. Dakota sandstone is tan to yellowish brown and is interbedded with dark gray.The Dakota Sandstone, for example, carries water over great distances beneath many States, including parts of North Dakota, South Dakota, Montana, Wyoming, Colorado, Nebraska, Kansas, New Mexico, and Oklahoma.

The sandstone originated from sand deposited on the floor of an ancient ocean. (A historical marker located in Sioux Falls in Minnehaha County, South Dakota.) 1.2 billion years ago intense heat and pressure transformed pure quartz sandstone into quartzite rock. The sandstone originated from sand deposited on the floor of an ancient ocean.Abstract. The Dakota sandstone and the overlying dense plastic shales form the most remarkable artesian basin in the United States with respect to its great extent, the long distances through which its water has percolated from the outcrops of the sandstone in the western mountains to the areas of artesian flow, and especially the tremendous ... Abstract The Dakota Sandstone in South Dakota is one of the classic artesian aquifers; it was first studied by N. H. Darton at the turn of the century. Since then, hydrogeologists have debated the source of the large quantities of water which have been discharged by artesian flow from the Dakota.The upper part of the Dakota Sandstone exposed on the Sevilleta National Wildlife Refuge, northern Socorro County, New Mexico, is a condensed, Upper Cretaceous, marine succession spanning the first five middle Cenomanian ammonite zones of the U.S. Western Interior. Farther north in New Mexico these five ammonite zones occur over a stratigraphic interval more than an order of magnitude thicker.The Dakota aquifer system is the most geographically extensive of all the aquifer systems in the upper 2,000 ft (600 m) of the subsurface of western and central Kansas. The geologic units that form the Dakota aquifer in Kansas are the Dakota Formation, the Kiowa Formation, and the Cheyenne Sandstone (table 1).The water table in North Dakota ranges between 15 and 50 feet deep, or 100 feet in upland areas. Fully wet areas are recognized in drill cores by unoxidized dark material. The lignite and sandstone of the Fort Union Group in the west is the top groundwater unit and a common source of water for farms and ranches. The Dakota Sandstone and its correlatives are a widespread package of sandy siliciclastics deposited in the ancient Western Interior Seaway of North America. The unit dates to the late Early Cretaceous and early Late Cretaceous The ridge in the photo is an outcrop of structurally tilted Dakota Sandstone in Dinosaur National Monument, Utah.

The strangely shaped rocks at Mushroom Rock State Park are made of sandstone from the Dakota Formation, deposited along the edge of a Cretaceous sea about 100 million years ago. Over time, circulating water deposited a limey cement between the sand grains, creating harder bodies of sandstone called concretions. Concretions are often spherical.Summary: Named as one of four formal named units of Dakota Sandstone for town of Paguate, 7 mi north of Laguna, Valencia Co, NM in San Juan basin.

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 Dakota Sandstone of probable Early and Late Creta-ceous age was deposited on a vast erosion surface, at least in . 226 the San Juan Basin area, of generally progressively older rocks from east to west as the Cretaceous trough bisecting North America formed and was flooded by the sea.
