The soils described are all clayey, from the states of California, Nevada, New Mexico, Virginia, North Carolina and South Carolina. They show xeric, torric (approaching ustic), ustic and udic moisture regimes, and have deep wide cracks which cause them to wet deeply. Striking differences were observed between the vertic subgroups and the Vertisols in their morphology and micromorphology, but it was not possible to distinguish them on the basis of physical and chemical properties alone.
