soils mostly shallow to bedrock in a complex of limy very gravelly over extremely cobbly loams with little or no development associated with limestone and better developed non-limy extremely channery loams over extremely channery clays related to phyllite; Pima County soil survey map unit 42 (Mabray-Deloro-Rock outcrop complex, 20 to 65 percent slopes) comprises 91% of the ELT
Geologic Materials:
alluvium, colluvium and residuum associated with upper Paleozoic strata (Pzu); Paleozoic carbonate rock (Pzc); Martin Formation (Dm); Holocene piedmont alluvium (Qy); and middle to late Pleistocene piedmont alluvium (Qi2) which comprise 38%, 26%, 13%, 5% and 5% of the ELT, respectively
