The Dakota Sandstone (also Cockrum Sandstone and Dakota Formation, more formally the Dakota Group) is a general term for an ill-defined early Cretaceous formation of the Rocky Mountains and Great Plains. It consists of sandy, shallow-marine deposits with intermittent mud flat sediments, and occasional stream deposits.[1][2] It is an important aquifer in some areas of the Great Plains.[2][3] It is frequently a porous sandstone and can reach thicknesses of more than 30 meters.
