coarse-silty, mixed, superactive, mesic Xeric Haplocalcid
(Owyhee series)

The platy structure in the C horizon reflects the lacustrine sediments that are the parent material for this soil. Soil development proceeds slowly in this arid climate and calicum carbonate, inherited from the parent material, is slow to leach from the profile. While the subsoil does contain an accumulation of calcium carbonate, the profile is moderately alkaline throughout. Sufficient leaching has occurred in the Bw horizon to allow the development of blocky structure and brighter soil colors. In time, the carbonates will move lower in the profile and clay translocation in the upper profile will begin. This soil is a member of the Owyhee series.
