This is one of a series of earth fissure maps prepared by the Arizona Geological Survey (AZGS) in accordance withAriz. Rev. Stat. 27-152.01(3). AZGS collected location information from previously conducted earth fissurestudies, reviewed available remote-sensing aerial and satellite imagery, and conducted surface site investigationsthroughout the study area. A reasonable effort was made to identify all earth fissures in the study area.Nonetheless, some fissures may remain unmapped as a result of one or more of the following:1) Existing fissures may have been masked by construction or agricultural activities.2) Incipient fissures may lack clear surface expression.3) The surface expression of fissures changes constantly as new earth fissures develop and old earth fissuresfill in. A blank area on the map does not guarantee earth fissures are not present. However, blank areaswithin the study area boundary have been investigated, and no surface evidence of fissures was found asof the date of map publication. Determining the presence or absence of a fissure at any specific site mayrequire additional mapping and/or geotechnical analysis.4) Some earth fissures mapped in this study area were previously referred to as 'combination earth fissuredesiccationcracks '(Harris, 2004). Based on similar appearance, morphology, and depth of surface crackto nearby known earth fissures, these features are depicted here as earth fissures. Other shallow polygonalsurface crack networks within the study area were interpreted to be giant desiccation cracks and are notdepicted on this map.

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 ArcInfo geographic information system (GIS). The resulting geologic map database (in ArcInfo format) can be queried in many ways to produce a variety of geologic maps. Digital base map data files. (topography, roadways, towns, and hydrography) are not included: they may be obtained from a variety of commercial and government sources. Geologic map graphics and plot files that are provided in the Open-File Report are representations of the digital database and are not designed to be cartographic products.

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 published in 2001. Staff and a contractor at the U.S. Geological Survey in Tucson, Arizona developed a digital geologic map database for the east map in 2001, made revisions to the previously released digital data for the west map (Drewes and others, 2001, ver. 1.0), merged data files for the east and west sheets, and added additional data not previously captured.

The Saint David 7 ' Quadrangle is located approximately 55 miles (88 km) west of downtownTucson. The map area encompasses the town of Saint David, a portion of the San Pedro River corridor,and the western piedmonts of the Little Dragoon and Dragoon Mountains. The San Pedro River flows northfrom Mexico to the Gila River. It occupies a broad valley inset below adjacent Pleistocene piedmont alluvialfans. The river is incised several meters below adjacent terraces and recently abandoned floodplains.Entrenchment occurred between 1890 and 1908 as a result of a series of large floods in conjunction withchanging land uses and population growth (Hereford, 1993). Once entrenched the channel widened to itscurrent width and eventually stabilized in the mid-1950s (Hereford, 1993).

The Galleta Flat East 7.5' Quadrangle is located in northwestern Cochise County in southeastern Arizona, north of the town of Benson. The San Pedro River flows south to north across the quadrangle and has been in a downcutting phase during the Quaternary. Lower Quaternary and upper Pliocene strata, which are exposed in bluffs and low hills flanking the river, were deposited in fluvial and lacustrine-margin to playa environments (Smith, 1994; Youberg et al., 2003). Bedrock exposed near the northern end of the Quadrangle consists of early Proterozoic Johnny Lyon Granodiorite and Pinal Schist (Cooper and Silver, 1964; Drewes, 1974).

Plan submitted by: RyanA1084 on 10/7/2021 USER DESCRIPTION: Single district map of CD2, extracted from the full state map titled 'Balanced CD Map - Full State'. All populations have been approximately balanced and districts have made competitive where possible. Unlike the Grid Map, CD2 in this map does not go into Cochise County, which has unique issues related to the Mexican border and military bases that distinguish it from the interests of the rest of CD2. This map designs CD2 to include as many tribal communities as possible. This results in a deviation of -3% in population in CD2.

Plan submitted by: AZ71@22 on 12/12/2021 USER DESCRIPTION: This map is based of LD 12.0 but balances out population and communities of interest in the Tucson and southern regions. USER PLAN OBJECTIVE: PLEASE REVIEW! Based off the LD 12.0 map, this map is primarily focused on Southern AZ, however all districts are drawn logically and population balanced. It accomplishes the requests of Mehl & Lerner: MEHL: LD17 includes Saddlebrook, Red Rock & the area south of Park Link Dr in Pinal County. It also now includes Picture Rocks and keeps Marana & Oro Valley together. LERNER: LD20 now has its city line drawn down Campbell Ave in the northern part of the city then jumps to Country Club Ave (halfway between Campbell & Alvernon) following Mayor Romero's request. It also incorporates the Pascua Yaqui Tribe in LD20. LD18 includes Tanque Verde and eastern Tucson separating Vail into LD19 along with Corona de Tucson. LD21 now combines Green Valley and Sahuarita in one district which many locals requested. Unfortunately, the Latino Coalition arm into Cochise County is eliminated as there is no way to population balance in Cochise County and still keep Santa Cruz County as one. (Plus I don't think it's wise to place Bisbee, the county seat of Cochise County, into a completely different district associated with another county). This map also incorporates some of the Yuma Gold map. LD23 is population balanced and shares Yuma with LD28 that stretches into the west Phx valley area. The same as LD23 stretches from Yuma into the west valley region of Tucson.

The McGrew Springs 7.5' Quadrangle is located in northwestern Cochise County about 45 miles southeast of Tucson, Arizona and lies south of the town of Benson. The western portion of the map encompasses a portion of the eastern flank of the Whetstone Mountains which is part of the Coronado National Forest. Kartchner Caverns State Park is located in the northwest corner of the map. The majority of the map area is covered by Quaternary fan and Tertiary basin fill deposits. Bedrock and surficial geology in the study area were mapped between October, 2002 and June, 2003 as part of a multiyear mapping program directed at producing geologic map coverage for the Karchner Caverns State Park and surrounding areas. Quaternary and late Tertiary deposits in the McGrew Springs 7.5' Quadrangle were partially mapped by Gray (1965) however this map does not separate the quaternary deposits from each other. Multiple phases of Quaternary alluvial fans top late Tertiary valley fill. Large outcrops of valley fill are exposed in the southeastern portion of the map which could be related to structure, however, there was no direct evidence for this structure in the mapped deposits.

The Fairbank map area is dominated by an Upper Cretaceous plutonic-volcanic complex that is closely associated with silver-rich, porphyry ore deposits of the Tombstone district (Goodale, 1927; Butler et al., 1938; Newell, 1974; Devere, 1978; Williams, 1980) located directly east of the map area. The volcanic rocks overlie Lower Cretaceous siliciclastic strata of the Bisbee Group with angular unconformity. The older rocks were folded into northwest-striking folds that show evidence for two phases of deformation. The Upper Cretaceous volcanics are moderately to gently tilted to the northwest forming two low-lying, southwest-striking horst blocks. A fairly major southeast-side-down normal fault, of probable middle Cenozoic age, is interpreted to cross the San Pedro valley diagonally from northeast to southwest just to the southeast of the northwestern horst block. A panel of volcaniclastic conglomerate of probable middle Cenozoic age is barely preserved overlying the volcanics along the northwestern flank of the northwestern horst block just to the north of this map area (Shipman and Ferguson, 2005). A small outcrop of similar conglomerate is tentatively identified overlapping the southeastern horst block. Another strip of conglomerate occurs parallel to and along the crest of the northwestern horst block, but this conglomerate dips steeply to the southeast and is bounded by a gently northwest-dipping normal fault. The age relationship between the two oppositely dipping conglomerate sequences and faults is unknown.

This map depicts the geology of the Huachuca City 7.5' quadrangle in Cochise County, southeastern Arizona, which consists almost entirely of upper Cenozoic surficial deposits. The map area is located between Benson and Sierra Vista along the western side of the upper San Pedro River Valley. The map area covers much of the southeastern piedmont of the Mustang and Whetstone mountains, part of the valley of the Babocomari River, and part of the northern piedmont of the Huachuca Mountains. It includes the small communities of Huachuca City and Whetstone, and the northern fringe of Fort Huachuca, a U.S. Army base. The quadrangle is roughly bisected by State Route 92, a major four-lane highway connecting the Sierra Vista area with Interstate Highway 10 to the north. The area was mapped during March through August, 2003. A 1:24,000 scale map is the primary product of this study. This map consists entirely of new mapping. The accompanying report describes rock units and other geologic features.

description: Aeromagnetic data were collected along flight lines by instruments in an aircraft that recorded magnetic-field values and locations. In the earlier days of surveying, the only way to represent this data was to generate an analog map with contour lines. This dataset is a representation of the digitized contour lines either by following the lines or by choosing the intersection of the contour and flight-line to create a value of the magnetic field. The values presented are latitude, longitude, and map magnetic-field values.; abstract: Aeromagnetic data were collected along flight lines by instruments in an aircraft that recorded magnetic-field values and locations.

The Mescal quadrangle straddles the divide between the Tucson basin to the westand the San Pedro Basin to the east. The region is dominated by Late Tertiary basin-filldeposits that form the low divide between the Whetstone Mountains to the south and theRincon and Little Rincon Mountains to the north. Interstate 10 crosses this low area justsouth of the drainage divide. The Mescal 7.5 quadrangle was mapped as part of theSTATEMAP program. Fieldwork was carried out between November, 2000 and April,2001 and was concurrent with mapping to the north in the Galleta Flat 7.5 quadrangle.The low, subdued nature of the area hides a complex geologic history. Shallowwaterplatform carbonate and mature clastic sedimentary rocks were deposited during thePaleozoic on an extensive erosion surface beveled across Proterozoic granitic andmetamorphic rocks. Erosion and faulting during the Late Jurassic led to infilling of theBisbee Basin by the upper Jurassic to middle Cretaceous Bisbee Group. The resultingsuccession of Paleozoic and Mesozoic strata in the Whetstone Mountains is one of thethickest sequences preserved anywhere in the state. These rocks were deformed duringcompression and thrust faulting during the Laramide orogeny at the end of theCretaceous. Laramide structures are now obscure because of overprinting by youngerdeformation, plutonism, and extensional. The region owes its present geography toyounger (Miocene) block-faulting that occurred during Basin-and-Range extension. LateTertiary (Late Miocene to Pliocene) sediments partially filled the low areas, and thesedeposits have been modified by repeated cycles of dissection and deposition during theQuaternary.
