Ogallala formation

Ogallala formation often sits directly on top of consolidated sediments, which are more than 250 million years old. In Cimarron and western Texas counties, a younger formation of shale and sandstone called the Dockum group overlies the redbed. Other formations, including the Dakota Sandstone and Morrison Formation, also are found in the Oklahoma.

Rocks found are part of Ogallala Formation (sand, gravel, and porous rock), which contains a large quantity of ground water and occurs only in western third of state. No rocks were formed in eastern Kansas. Mesozoic: Cretaceous: 77,600,000: Much of western half of Kansas was covered by seas.In 1965, the Fifth Circuit Court of Appeals held that groundwater in the Ogallala formation in the Southern High Plains of Texas and New Mexico was a depletable mineral and natural deposit.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.

Chert. The rock within the Ogallala formation here referred to as chert occurs as irregular areas of uneven or spotty silicification of "caliche" or "marl" that contain various amounts of silt or sand. Smith (1940, p. 46) has described an exposure of this chert in western Clark County as follows:The Ogallala formation has been described as braided stream deposits made up of broad, thinning, and shallow channels throughout (McMillan et al. 2002).
