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 83 (Tombstone-Stronghold complex, 5 to 30 percent slopes) and 62 (Nolam-Stronghold complex, 5 to 30 percent slopes). These units comprise 89% and 7% of the ELT, respectively
Geologic Materials: 
alluvium and residuum associated with basin fill, not tilted, may include some Paige Gravel (QTs); Paige gravels (Tsy); and Johnny Lyon Granodiorite (Xgl) which comprise 59%, 13% and 7% of the unit, respectively
Landforms: 
moderately to finely dissected, weakly to moderately incised fan and pediment surfaces
