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 68% and 23% of the ELT, respectively
Geologic Materials:
dominated by Holocene piedmont alluvium, undivided (Qy); Holocene to Pleistocene alluvium (Qyl); late Holocene deposits in active stream channels and low terraces (Qy2); modern channel deposits (Qyc); and late to latest Pleistocene piedmont alluvium (Qi3r, Qi3) which comprise 50%,12%, 12%, 9% and 6% of the unit, respectively
