The Niobrara Formation / ˌnaɪ.əˈbrærə /, also called the Niobrara Chalk, is a geologic formation in North America that was deposited between 87 and 82 million years ago during the Coniacian, Santonian, and Campanian stages of the Late Cretaceous.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.In most of the aquifer area, the Ogallala Formation of Miocene age and overlying hydraulically connected Quaternary deposits, if present, are the principal geologic units in the aquifer.

Other geologists hypothesize that today's Colorado Rockies rose to their current height within the last 5 million years. Their primary evidence is that before 5 million years ago, sand and gravel were accumulating across the western Great Plains, producing the Ogallala Formation, the rock unit that forms the important Ogallala Aquifer.
The Ogallala Formation originated from the Rocky Mountains of Colorado and New Mexico. This formation covered portions of the Great Plains, extending from central Texas to southern South Dakota. These rocks filled in valleys and covered mesas. In some areas, outside of the park, this formation became over 500 feet thick.

Ogallala sediments were deposited by streams flowing eastward from the Rocky Mountain region in broad, relatively ...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.

Older sedimentary bedrock units underlie the aquifer. Evaporation rates are some of the highest in the Nation, owing to
The Ogallala Formation in Kansas includes strata of Miocene and earliest Pliocene age, revising earlier correlation to the Pliocene only (Zeller, 1968). The Kansas Geological Survey is abandoning use of the term "Tertiary," to be replaced by the term "Neogene." International stage boundaries for the Neogene have not been established in Kansas.

Although most recent literature hasAfter deposition of the Ogallala Formation about 5 million years ago, Nebraska saw a switch from its long depositional history to an erosional regime. Geologists continue to debate whether this switch was caused by renewed uplift of the Rockies and the Great Plains or was, instead, the result of changes in global climate that invigorated the ...The Ogallala Formation is a Miocene to early Pliocene geologic formation in the central High Plains of the western United States and the location of the Ogallala Aquifer.
