Ogallala formation.

When a water-bearing rock readily transmits water to wells and springs, it is called an aquifer. Wells can be drilled into the aquifers and water can be pumped out. Precipitation eventually adds water ( recharge) into the porous rock of the aquifer. The rate of recharge is not the same for all aquifers, though, and that must be considered when ...

At least four mammalian ichnotaxa are represented, including a ...May 24, 2018 · This 300-meter-thick pile of sediment became the White River and Arikaree groups and the younger Ogallala Formation. The gently east-sloping surface of this sediment pile became the surface of the High Plains. The uppermost layers of the White River Group are composed of 33-million-year-old sediments from the Brule Formation. water created the aquifer, and the water sitting in the Ogallala Formation is ancient glacial water from the Rocky Mountains.

Most of the audited sites were extracting water from either the Rush Spring or Ogallala aquifers. The average groundwater depth was 104 feet for the wells tapping the Rush Spring and 273 feet for the Ogallala aquifers. Figure 5.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.The Ogallala Formation is Miocene and earliest Pliocene in age, and Zeller (1968) is revised accordingly.

The Cheyenne area is on broad tablelands that form part of the High Plains aquifer. Surficial deposits, along with the Ogallala Formation and the White River Group, are included in the High Plains aquifer in the study area, and both unconfined and confined ground-water conditions exist within 100 feet of land surface. During wet years, shallow ground-water problems affect urban development.

Origin of the Ogallala Aquifer. The Ogallala formation in Texas is the southernmost extension of the major water-bearing unit underlying the physiographic province of North America.
