The Ogallala Formation was named by Darton (1899) from a locality in southwestern Nebraska that he later (1920) referred to as Ogallala Station. Elias (1931, 1932, 1935, 1942) made detailed studies of the Ogallala in western Kansas and described fossil endocarps, nutlets, and anthoecia from the ... These calcareous soils form the hard and durable caprock horizons that cover much of the Southern High Plains. Geologists have included these deposits within the Ogallala Formation or Group. These strata comprise the majority of sediments in the High Plains aquifer, the primary source of groundwater in the Southern and Central Great Plains.

Neither do the Trujillo and Ogallala Formations—the next-highest in the canyon. The supposedly 10-million-year-old Ogallala, the caprock that forms the canyon's upper rim, stretches from Texas all the way up to South Dakota. 4 My daughter Abby and I could span our hands across this assumed 200-million-year gap. A total lack of ruts or ...The Ogallala aquifer, which underlies the Southern High Plains, consists of the saturated sediments of the Neogene Ogallala Formation. The aquifer is the main source of water for the High Plains of Texas and New Mexico and is being severely depleted by extensive pumpage for irrigation. ….

The Ogallala Aquifer is one of the world’s largest fresh groundwater resources. It underlies 175,000 square miles in eight states. Starting as hundreds of feet of silt, clay, and gravel eroded from the Rocky Mountains and laid down by streams millions of years ago, rainfall during this time produced an underground lake the size of Lake Huron.The Ogallala Formation was named by Darton in 1899 from outcrops in Keith County, Nebraska. These beds had previously been referred to as part of the Loup Fork Formation, now an obsolete term. Darton considered the Ogallala to be equivalent, at least in part, to the "mortar beds," "tertiary grit," and "magnesia beds" of Kansas.As the sediments of the Ogallala Formation are sourced in the Rocky Mountains, this question has been intimately linked to what process drove this major late Cenozoic erosional event, producing ...

The Ogallala of northern Kansas meets all the stated requirements of a formation (Ashley and others, 1933). Although it contains a wide range of lithologic types, it is essentially a continuous blanket of alluvium that may be regarded as "homogeneous in its heterogeneity"; it is considered a conformable sequence, as the multitude ... Ogallala formation reveal that, in 1968, water withdrawn as groundwater from the Ogallala was almost twice as much as the total water usage from all the surface storage in the area. Most of the present withdrawals is for irrigation purposes; about 22% is for municipal and industrial use, and a small percentage is used in water-flooding of oil craigslist paterson 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.
