Digital boundaries of the alluvial and terrace deposits along the Cimarron River from Freedom to Guthrie in northwestern Oklahoma

The objective was to create and document a digital geospatial data set from a published report or map, or existing digital geospatial data set that could be used in ground-water vulnerability analysis. This data set consists of digital aquifer boundaries for the alluvial and terrace deposits along the Cimarron River from Freedom to Guthrie in northwestern Oklahoma.

Ground water in 1,305 square miles of Quaternary-age alluvial and terrace deposits along the Cimarron River from Freedom to Guthrie is an important source of water for irrigation, industrial, municipal, stock, and domestic supplies. Alluvial and terrace deposits are composed of interfingering lenses of clay, sandy clay, and cross-bedded poorly sorted sand and gravel. The aquifer is composed of hydraulically connected alluvial and terrace deposits that uncomfortably overlie the Permian-age Formations.
