Digital geologic map of Arizona: a digital database derived from the 1983 printing of the Wilson, Moore, and Cooper 1:500,000-scale map

The Geologic Map of Arizona was compiled at a scale of 1:500,000 by Eldred D. Wilson, Richard T. Moore and John R. Cooper, in 1969 and reprinted in 1977, 1981, and 1983. Comparison of an acetate copy of the 1983 map with existing paper copies of earlier m

Digital data for construction material sources reported by the Arizona Department of Transportation in 1977 for Maricopa County, Arizona

The data set marpits1 is an ArcInfo coverage of point features representing pit locations and attribution data captured from an atlas of map sheets and pit data sheets titled "A Materials Inventory of Maricopa County [Arizona]" by the Arizona Highway Dep

Spatial Digital Database of the Geologic Map of Catalina Core Complex and San Pedro Trough, Pima, Pinal, Gila, Graham, and Cochise Counties, Arizona

A paper copy of the Geologic Map of the Catalina Core Complex and San Pedro Trough (Dickinson, 1992) was scanned and digitized by U.S. Geological Survey staff and contractors at the Southwest Field Office (Tucson, AZ) in 2000-2001 for input into an ArcInf

Spatial Digital Database for the Tectonic Map of Southeast Arizona

A spatial database was created for the Drewes (1980) tectonic map of southeast Arizona: this database supercedes Drewes and others (2001, ver. 1.0). The west tectonic map (Drewes, 1980) was converted to digital format by Optronics Specialty Co., Inc. and

Spatial digital database for the geology of the San Pedro River basin in Cochise, Gila, Graham, Pima, and Pinal Counties, Arizona

This open-file report is a digital representation of the Dickinson (1993, 1998, 2000) remapping of the post-Mid- Miocene Quiburis Formation in southeastern Arizona. It delineates constituent facies of the Formation throughout the San Pedro trough.
