Soil Summary:
very deep, very gravelly sandy loam to sand surface soils over gravelly, very gravelly and extremely gravelly sandy loam to sand subsurface layers, soils are limy throughout, moderate to strong development (lime accumulation and cementation); other soils associated with draws and washes are very deep, sandy loams over fine sandy loams, sandy loams, and very gravelly sandy loams, limy throughout, little or no development (relatively recent alluvium); this unit is dominated by Pima County map units 67 (Redo very gravelly sand, 15 to 50 percent slopes and 3 (Anthony fine sandy loam, 0 to 3 percent slopes) which comprise 76% and 21% of the ELT, respectively
