ELT 8c
Soil Summary:
very deep; very gravelly clay loam and very gravelly sandy loam surface layers over gravelly, very gravelly and extremely gravelly sandy loam, gravelly and very gravelly clay loam subsurface layers; lime at or near the soil surface; modest development (lime and clay accumulation); dominated by Pima County soil survey map units 61 (Pinaleno-Stagecoach complex, 10 to 35 percent slopes) and 60 (Pinaleno-Stagecoach complex, 5 to 16 percent slopes). These units comprise 70% and 15% of the ELT, respectively
Geologic Materials:
alluvium and residuum associated with Pleistocene piedmont alluvium (Qi2, Qi, Qi1, Qi1r, Qi2r, Qi3, Qy), Pleistocene river terraces (Qir, Qy2), old alluvium (QTs), sandstone, siltstone, and conglomerate, undivided (QTs), and small areas of rock exposure (mostly granodiorite) which comprise 84%, 1%, 10%, 4% and 1% of the unit, respectively
