Cleaver Profile
Cleaver Profile	This profile is 30 cm thick over a horizon that is cemented with CaCO3. A hard, cemented horizon like this is a petrocalcic horizon. The carbonate may come from dust, from the reaction of CO2 from root and microbial respiration with pore water and/or from weathering of parent material. This soil is formed in gravelly alluvium in the Mojave desert. It is weakly developed over the cemented horizon. A little red color development can be seen in the profile, but there is little clay accumulation.
