The Ogallala Formation has a thickness from 0 to approximately 800 feet, with an average saturated thickness of 95 feet . Throughout most of the Ogallala Aquifer area, withdrawal of water has exceeded the recharge rate. Water levels have declined in excess of 300 feet in the last 50 to 60 years. The use of groundwater from the Ogallala is ...The Ogallala Formation consists of eolian (wind-blown) sand and silt and fluvial (stream or river) and lacustrine (lake) sand, silt, clay, and gravel derived from the Rocky Mountains between middle Miocene and early Pliocene time, about 1–12 million yrs (m.y.) ago (Reeves, 1972; Hawley, 1984, 1993; Gustavson et al., 1991). Most of the area of the Pierre is covered by the younger Ogallala Formation. Several outliers both on the surface and in the subsurface are present east of the eastern margin of the formation. These are located in Phillips, Norton (Frye and Leonard, 1949), Graham, Gove, and Logan Counties. Remnants in Gove and Logan Counties are preserved in ...The Ogallala Formation of Neogene (Pliocene) age unconformably overlies Cretaceous rocks in much of the county and consists principally of fluviatile deposits of sand, gravel, and silt. Terrace deposits of Pleistocene age occur along the principal valleys. Eolian silts that mantle the uplands and alluvium along stream valleys constitute the ...Tweet. The Ogallala Aquifer is a shallow table aquifer that sits under eight states ranging from South Dakota south to Texas and New Mexico. It is a major source of irrigation water throughout the region. Formation of the Ogallala Aquifer. Before the Aquifer formed, the land now known as the Great Plains looked nothing like it does now.

The silicified rocks of the Ogallala formation are grouped, on the basis of their texture, color, degree of cementation, and predominant lithology of the original deposit, into two major categories--here termed quartzite and chert--and several special types of minor extent and importance. ...

placers are found in the Ogallala(?) Formation, which in this area is a fanglomerate of local derivation, and in the Holocene alluvium. Gold in the placers was derived through selective concentration of gold in minor vein deposits and low-grade disseminations in the upper Eocene or lower Oligocene laccoliths and sills of the Jicarilla MountainsOgallala Formation (To). 4 crease in seismic velocity within the FGZ. Further, water-saturated sediment within the perched aquifer likely has higher density, seismic velocity, and electrical conductivity than similar unsat-urated stratigraphic intervals. These observations from existing data suggest that seismic and

The member names for the Ogallala Formation (including the Valentine, Ash Hollow, and Kimball) in Kansas of Zeller (1968) are abandoned. The Ogallala Formation in Kansas includes strata of Miocene and earliest Pliocene age, revising earlier correlation to the Pliocene only (Zeller, 1968). Much of the Ogallala Formation was eroded away and stream channels became established. Sketch courtesy of Wyoming Geological Survey. Today, the Laramie Range , a northern extension of the Colorado Front Range, extends from the Colorado—Wyoming state line north and west to near Casper, Wyoming.
