Abstract
The Cheyenne area is on broad tablelands that form part of the High Plains aquifer. Surficial deposits, along with the Ogallala Formation and the White River Group, are included in the High Plains aquifer in the study area, and both unconfined and confined ground-water conditions exist within 100 feet of land surface. During wet years, shallow ground-water problems affect urban development. The High Plains aquifer is considered an aquifer system in the Cheyenne area. Water-yielding sandstone and conglomerate units are surrounded by sequences of clay and silt; although the water-yielding units under confined conditions may be areally extensive, they are not easily identified. Urban development has modified the High Plains aquifer system locally as indicated by the mapped potentiometric surfaces, the perched water zones, and the surface-drainage patterns. That part of the system in the shallow zones is affected by excavations and by structures that penetrate the saturated zones.
