Soil Summary:
dominant soils are very shallow to shallow to conglomerate and very deep, very gravelly fine sand or sandy loam surfaces over often stratified fine sand, sand, and gravelly coarse sand or sandy loam subsurface layers, mostly limy throughout, no or little soil development; unit is dominated by Cochise County, Northwestern Part soil survey unit 68 (Redington-Ripsey-Rock outcrop assoication, 15 to 70 percent slopes). This unit comprises 95% of the ELT
