Ogallala formation.

The Ogallala aquifer is a sandstone formation that underlies some 583,000 square kilometers of land extending from northwestern Texas to southern South Dakota. Water from rains and melting snows has been accumulating in the Ogallala for the past 30,000 years. Estimates indicate that the aquifer contains enough water to fill Lake Huron, but ...The late Miocene Ogallala Formation hosts much of the High Plains aquifer of North America, though it is poorly studied in the central High Plains region where only a small fraction of its total thickness is exposed. One exception is in western Kansas, where up to 40 m of the Ogallala Formation crop out along the bluffs of Ladder Creek Canyon. ...Deposition of the basal fluvial sediments of the Miocene-Pliocene Ogallala Formation in western Texas and eastern New Mexico was controlled by topography on the underlying erosional surface. Paleovalley-fill facies consist of gravelly and sandy braided-stream deposits interbedded with and overlain by eolian sediments deposited as sand sheets ...Other colors generally light tan or buff but locally may be pastel shades of almost any color. The Laverne and Rexroad Formations of Pliocene age and the Meade Group and Odee (of local usage) and other formations of Pleistocene age occur locally and are included with the Ogallala Formation, 0-700 feet thick.The Ogallala is the leading geologic formation in what is known as the High Plains Aquifer System. The entire system underlies about 450,000 square kilometers (174,000 square miles) of eight states.

Dec 28, 2006 · The northern boundary of the Raton section is placed somewhat indefinitely at the northern limit of the area injected by igneous dikes. The eastern boundary of the Raton section is at the eastern margin of the lavas of Mesa de Maya and adjoining mesas, where lava-capped outliers of Ogallala Formation are separated from the Ogallala of the High Plains only by the canyon of Carrizo Creek.

The Ogallala Formation is the principal geologic unit in the High Plains aquifer in eastern Colorado and New Mexico. The Ogallala generally consists of an unconsolidated and poorly sorted sequence of gravel, sand, silt, and clay. Moderately to well-cemented zones within the Ogallala are resistant to weathering and form ledges in outcrop areas. The Tertiary Ogallala Formation directly overlies the Permian red beds, although Triassic sedimentary rocks are present in the southwestern part of Lake Meredith NRA. The approximately 10-million-year-old Ogallala Formation is much younger than the underlying rocks, and sits atop a regional uncomformity, or period of missing time. ...

Wilson said 80-90% of the water used in the Ogallala aquifer region goes to irrigation. That averages out to about 2.5 billion gallons a day, pumped up and sprayed on crops. It can't go on like that forever. Estimates show that if pumping trends continue, more than two-thirds of the water under Kansas will be gone within 40 years.The Ogallala Formation, Pleistocene deposits, and alluvium combine to form the High Plains aquifer. Water Resources in the High Plains Aquifer. Usable water in the High Plains aquifer is in the pore spaces between particles of sand and gravel. This water (called groundwater) accumulated slowly--in some of the deeper parts of the aquifer, over ...In 2001, Kansas formed a special citizens' committee to advise the governor and legislature on potential groundwater conservation policies (Ogallala Aquifer ...In turn, the Ogallala Formation was subdivided into a lower unnamed member and an upper member, the Rexroad. In Ford County, Waite (1942) assigned all the Tertiary deposits to the middle and upper Pliocene Ogallala Formation. The Ogallala was further subdivided into two members following Frye (1942). In Finney and Gray counties, Latta (1944 ...

to soils developed on alluvium and the Ogallala Formation than to those developed on the Blackwater Draw Formation. Soils on windblown sand were given the greatest recharge weighting factor. The three combined soil-texture groups break out major trends in recharge patterns, following the approach of Mullican and others (1977), but do not break

Between 1950 and 2013, the water levels dropped over 250 feet in an Ogallala well near Lubbock, Texas. The aquifer has seen more moderate declines elsewhere, but it's causing problems for cities, well owners and irrigators alike. Oklahoma only permits its irrigators enough groundwater to cover each acre of their land with 2 feet of water per ...

Part of the Colorado Plateau and Basin and Range, this red sandstone …posited Ogallala rocks. During this time, as the various streams con-tinued their meandering, deposi-tion of the Ogallala formation oc-curred. This aggradational pro-cess deposited the various grav-els, sands, silts and clays that com-prise the thickness of the Ogallala section. Depending on the topog-raphy of the pre-Ogallala surface,Map of the Ogallala Aquifer. Lubbock, Texas, the Hub City of the South Plains, sits atop the southern range of the Ogallala Aquifer. Thanks to this massive natural formation, in this part of the world, cotton is king because center-pivot irrigation lapping up the fossil water of the Ogallala Aquifer has made these sunny grasslands highly productive.tilting of the Ogallala Formation, east of the Rio Grande rift on the western Great Plains. The cause of this unconformity is currently debated (Cather et al., 1994; Chapin, 2008; Connell et al., 2013; Nereson et al., 2013), and because earlier studies did not appreciate its spatial extent, an evaluation of postulated explanations is needed.The Ogallala Formation is composed of pedogenically modified fluvial silts, sands, and gravels.

In Kansas, the aquifer comprises three components — the Ogallala aquifer, the Great Bend Prairie aquifer and the Equus Beds. Of these, the Ogallala aquifer underlies most of western Kansas and consists mainly of the Ogallala Formation, a geologic unit that formed from sediment eroded off the uplifting Rocky Mountains.The Ogallala formation of Pliocene age, which under­ lies most of the upland, yields moderate quantities of water to wells in an area west of the city of Cheyenne. East of Cheyenne, the saturated thickness of the Ogallala forma­ tion is not sufficient for that formation to yield large quantities of water to wells, but ...The northern boundary of the Raton section is placed somewhat indefinitely at the northern limit of the area injected by igneous dikes.

Depth to groundwater in feet below land surface was measured at each well before sampling to determine the water-quality sampling depths. Water-quality samples were ...Ogallala Formation all probably experienced unique histories. Consequently, little logical support exists for an expectation of regional lithostratigraphic continuity along the north-south extent of the Ogallala Formation. Moore et al. (1944) and Frye et al. (1956) adopted member names of the Ogallala Formation in Kansas that were

The Ogallala formation is composed of a wide range of sediment types, from gravels to sands, silts, and clays, sourced from the Rocky Mountain region to the west during the Miocene and Pliocene Epochs. The Laramide uplift of the Rocky Mountains lasted from about 80 million years ago until about 35 million years ago.
