Soil Summary: 
dominant soils that are shallow and moderately deep to a caliche hardpan, have very gravelly sandy loam surfaces over very and extremely gravelly sandy loam and sandy clay loam subsurface layers, are limy throughout and have strong development (lime accumulation and cementation); unit is dominated by Pima County soil survey map unit 65 (Powerline-Kimrose family complex, 10 to 35 percent slopes). These units comprise 90% of the ELT, respectively
Geologic Materials: 
alluvium and residuum associated with sandstone, siltstone, and conglomerate, undivided (QTs); middle to late Pleistocene piedmont alluvium, undivided (Qi) and Holocene piedmont alluvium, undivided (Qy) which comprise 79%, 9% and 9% of the unit, respectively
