Ogallala Formation is a calcareous grit or soft limestone containing a greater or less amount of interbedded and intermixed clay and sand, with pebbles of various kinds sprinkled through it locally, and a basal bed of conglomerate at many localities. In places it merges into aMap of the Ogallala Aquifer. Lubbock, Texas, the Hub City of the South Plains, sits atop the southern range of the Ogallala Aquifer. Thanks to this massive natural formation, in this part of the world, cotton is king because center-pivot irrigation lapping up the fossil water of the Ogallala Aquifer has made these sunny grasslands highly productive.The Oklahoma Panhandle and adjacent areas in Texas, Kansas, Colorado, and New Mexico have prospered because of the development of supplies of fresh water and of oil and gas.

The formation of the Ogallala Aquifer started 24 million years ago, and ended 1.8 million years ago, according to an MIT Mission 2012 Clean Water report. This happened as sand and gravel that had eroded from the Rocky Mountains were carried eastwards by large rivers, and these sediments ended up covering the Great Plains landscape.The Ogallala Aquifer that’s better known as High Plains Aquifer underlies an area of about 174,000 square miles that extends through parts of eight states of the Midwest United States.
