Soil Summary:
dominant soils are very deep, very gravelly fine sandy loam over very gravelly sandy clay loam subsoils or very gravelly and gravelly sandy loam subsurface layers, lime within a foot of the soil surface or throughout, moderate development (clay and/or lime accumulation), other soils are very gravelly loamy sand over gravelly sandy loam and are limy throughout, moderate development (lime accumulation); unit is dominated by Cochise County, Northwestern Part soil survey units 62 (Nolam-Stronghold complex, 5 to 30 percent slopes) and 83 (Tombstone-Stronghold complex, 5 to 30 percent slopes).
