A Mohave sandy loam profile, representative of Red Desert soils, developed in the Avra Valley in southern Arizona was studied to determine its pedogenesis. A lithologic discontinuity was found at a depth of 60 inches which separates the soil profile from an underlying caliche layer. Only a weak and relatively recent carbonate accumulation is pedogenically associated with the present soil surface. Kaolinite and illite are the predominant clay minerals in the upper layer. Thin sections reveal few clay skins developed in the profile.
