Soil Summary: 
mostly shallow to bedrock, a complex of limy very gravelly over extremely cobbly loams with little or no development associated with limestone, better developed extremely channery loams over extremely channery clays related to phyllite and lacking lime, and limy extremely gravelly loams associated with sandstone ; unit dominated by Pima County soil survey map unit 23 (Deloro-Andrada complex, 5 to 35 percent slopes) and 42 (Mabray-Deloro-Rock outcrop complex, 25 to 60 percent slopes). These units comprise 76% and 21% of the ELT, respectively
