Soil Summary: 
very deep; very gravelly clay loam, gravelly sandy loam, and very gravelly sandy loam surface layers over gravelly, very gravelly and extremely gravelly sandy loam, gravelly and very gravelly sandy clay loam subsurface layers; lime depth ranges from the surface to more than a foot below the soil surface; modest development (lime and clay accumulation); dominated by Pima County soil survey map units 60 (Pinaleno-Stagecoach complex, 5 to 16 percent slopes) and 61 (Pinaleno-Stagecoach-Palos Verdes complex, 10 to 35 percent slopes). These units comprise 67% and 30% of the ELT, respectively
Geologic Materials: 
alluvium and residuum associated with old alluvium (QTs), Pleistocene river terraces (Qir, Qy2,Qyr), Pleistocene piedmont alluvium (Qi2, Qi, Qi1, Qi1r, Qi2r, Qi3, Qy), and small areas of rock exposure, mostly limestone and related rocks which comprise 47%, 31%, 12% and 9% of the unit, respectively
Landforms: 
finely dissected, moderately to deeply incised fan and pediment surfaces
LTA 8
Upper Sonoran desert on fans, terraces and weakly consolidated pediments with limy soils
