MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Raleigh, North Carolina
SERIES ESTABLISHED: Rockingham County, North Carolina, 2009.
REMARKS: Casville soils were previously mapped as Vance soils. The creation of a mesic region within the southern Piedmont necessitated a new series be established as a counterpart to the Vance Series. Casville is a small community in western Caswell County near the Rockingham County line.
