Soil Summary: 
very deep, textures vary widely and soils are often stratified – very fine sandy loam to silty clay surfaces with very gravelly coarse sand to silty clay layers below, limy, no or little development, some high water tables on lower terraces; dominated by Cochise County, Northwestern Part soil survey units 48 (Hantz complex,Chihuahuan, 0 to 2 percent), 50 (Hantz silt loam, saline-sodic, 0 to 3 percent slopes), 42 (Glendale silty clay loam, 0 to 1 percent slopes), and 17 (Cascabel, Quiburi soils, and Riverwash, Chihuahuan, 0 to 5 percent slopes). These units comprise 44%, 26%, 15%, and 14% of the ELT, respectively
Geologic Materials: 
river alluvium associated with Holocene alluvium (Qy) and active channel and Holocene terraces (Qyr) which comprise 84% and 16% of the ELT, respectively
Landforms: 
coarsely dissected, weakly to moderately incised mainly on river terrace breaks; terraces themselves show little dissection
