Soil Summary:
mostly shallow to bedrock, a complex of better developed extremely channery loams over extremely channery clays related to phyllite and lacking lime and limy extremely gravelly loams associated with sandstone; dominated by Pima County soil survey map units 24 (Deloro-Rock outcrop complex, 15 to 60 percent slopes) and 23 (Deloro-Andrada complex, 5 to 35 percent slopes) which comprise 43% and 36% of the ELT, respectively
Geologic Materials:
alluvium, colluvium and residuum associated with the Bisbee Group (Kbs); Holocene alluvium (Qy); and basin fill deposits and conglomerate with colluvial veneer (QTs, QTsc) which comprise 46%, 33% and 10% of the ELT, respectively
