Reaction is extremely acid to strongly acid. The 2C horizon has hue of 10YR, value of 4 or 5, and chroma of 4 to 6. Texture is stratified gravelly to extremely gravelly analogues of loam to coarse sandy loam. Some pedons have strata of very gravelly or extremely gravelly loamy sand. Rock fragments range from 25 to 80 percent.
Cobbles are present in some pedons.
Strata of coarser textured material with lower rock fragment contents are present in some pedons. Reaction is very strongly acid to moderately acid. Blocher soils have, in some part of the particle size control section, a clay content of more than 30 percent. El Dara soils do not have subhorizons with as much as 15 perecnt rock fragments in the particle size control section. Kidami soils have a higher pH in the lower part of the subsoil.
