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); other soils are finer textured and very deep, typically silt loam surfaces over silty clay and clay subsurface layers, lime and gypsum concentrations occur throughout, moderate to strong development (lime and gypsum accumulation, clay accumulation); dominated by Cochise County Northeastern Part soil survey map unit 14 (Calcigypsids-Contention-Redo complex, Chihuahuan, 5 to 45 percent slopes). This unit comprises 91% of the ELT
Geologic Materials:
alluvium and residuum associated with the Pliocene-Pleistocene conglomerate and sandstone (QTcs); sandstone, siltstone and conglomerate, undivided (QTs); Holocene piedmont alluvium, undivided (Qy) and Late Pliocene-Early Pleistocene relict basin floor deposit (QTbf)which comprise 56%, 21%, 12% and 5% of the ELT, respectively
