The area described is part of an oil-field region in southwestern Russell County, in the Plains Border section of the Great Plains physiographic province.
The rocks encountered in test holes in this area are of Permian, Cretaceous, Tertiary (?), and Pleistocene age. They include the Cedar Hills sandstone (?) and Salt Plain formation (?) of Permian age; the Cheyenne sandstone, Kiowa shale, Dakota formation, Graneros shale, Greenhorn limestone, and Carlile shale of Cretaceous age; upland sand, silt, and gravel of Tertiary (?) age; and Pleistocene terrace deposits of sand, gravel, and silt. The Dakota formation and younger deposits listed are exposed in this area.
Petrographic methods of distinguishing between the various formations are discussed. It is concluded that the Cheyenne sandstone consists of two types of sand and that its eastern boundary is not in the area studied.
The waters sampled from test holes in the area generally are not potable, and the water in the deeper formations is highly mineralized. Some of the water in the Dakota formation is believed to have come from older Cretaceous and Permian rocks.
