The Ogallala formation in Texas is the southernmost extension of the major water-bearing unit underlying the physiographic province of North America. It was named in 1898 by N.H. Darton for the town of Ogallala, Nebraska, near where the formation was discovered.The Ogallala Formation of the High Plains is composed of individual particles of clay, silt, sand, and gravel. The spaces between these particles may be completely filled with water. Where this occurs, the formation is said to be saturated with water. The first recovery, development, of water is by pumpingThe 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.

The age of the Ogallala Formation is considered to be Miocene in this chapter, but is listed as Pliocene or Pliocene and Miocene in many published reports. At the close of deposition of the Ogallala Formation several million years ago, the Great Plains was a vast, gently sloping plain that extended from the edge of the Rocky Mountains eastward ...The upper Tertiary Ogallala Formation in original or reworked form has been suggested as the source of the dune sand by Lugn (1935, 1960, 1962). Stanley and Wayne (1972) and Reed and Dreeszen (1965), among others, suggested a lower Pleistocene alluvial source. We conducted a mineralogic study of 7 dune and inter­

Moss opal is found in the Ogallala Formation and contains inclusions of various iron minerals. The stone's inclusions resemble moss's small collection of branching tendrils. Some refer to moss opal as "dendritic opal" because the inclusions could be called dendrites. The most common iron mineral present in moss opal is manganese oxide.The High Plains aquifer consists of one or more hydraulically connected geologic units of late Tertiary or Quaternary age, underlain by bedrock units that range in age from Permian to Tertiary.

Aeolian processes, also spelled eolian, [1] pertain to wind activity in the study of geology and weather and specifically to the wind's ability to shape the surface of the Earth (or other planets ).

The Ogallala Formation is the most extensive hydrogeological unit, which makes up about three-fourths of the total High Plains region (McMahon et al., 2007). The unsaturated-zone thickness ranges from 0 to approximately 152m and averages about 30.5m.(340 to 390 ft day ), while in the Ogallala formation the range is 5.2 to 5.8 m d –1 (17 to 19 ft day). The vertical hydraulic conductivities are 10.4 m d –1 (34 ft day ) for the primary aquifer, 3.1 to 6.1 cm d (0.1 to 0.2 ft day –1) for the Ogallala aquifer, and 0.18 to 0.31 cm d –1 (0.006 to 0.01 ft day) for the aquitard.

Stratigraphy. Silicified rock was found to occur at many stratigraphic positions within the Ogallala formation. As noted by Elias (1931, p. 136) chert occurs in Wallace County, Kansas, a few feet below the "Algal limestone," which is presumed to mark the top of the formation, and rock that is believed to be equivalent to this limestone was found to be partly silicified near Lamesa, Texas.
