Soil Summary:
very deep, textures vary widely and soils are often stratified – very gravelly fine sand to sandy loam surfaces with extremely gravelly sand to fine sandy loam layers below, limy, no or little development (relatively recent alluvium); this unit is dominated by Pima County map units 3 (Anthony fine sandy loam, 0 to 3 percent slopes) and 5 (Arizo-Riverwash complex, 0 to 3 percent slopes) which comprise 60% and 37% of the ELT, respectively
Geologic Materials:
dominated by Holocene piedmont alluvium, undivided (Qy); Holocene channel deposits and terraces (Qyr); late to latest Pleistocene piedmont alluvium (Qi3r, Qi3) which comprise 57%, 20% and 14% of the unit, respectively
