Soil Summary:
dominant soils are very shallow and shallow to granite and similar rocks; very cobbly loams or very gravelly sandy loams throughout, some soils with gravelly clay loam surfaces and gravelly clay and clay subsoils; no lime; no to moderate soil development (clay accumulation); dominated by Pima County soil survey map units 40 (Lampshire-Romero- Rock outcrop complex, 10 to 65 percent slopes), 14 (Cellar-Rock outcrop complex, 30 to 65 percent slopes), and 13 (Cellar-Lehmans complex, 5 to 25 percent slopes). These units comprise 47%, 27% and 25% of the ELT, respectively
Geologic Materials:
alluvium, colluvium and residuum associated with the Catalina-Rincon igneous metamorphic complex (TXm, TXmy) and Pleistocene piedmont alluvium (Qi2, Qi3) which comprise 97% and 3% of the unit, respectively
