MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Morgantown, West Virginia
SERIES ESTABLISHED: Frederick County, Maryland, August 1997.The name Burkittsville is taken from a small community in the area.
REMARKS: Diagnostic horizons and features in this pedon include:
Ochric epipedon - from a depth of 0 to 10 inches (Ap horizon).
Argillic horizon - from a depth of 10 to 35 inches (Btl and Bt2 horizons).
Paralithic contact below a depth of 60 inches.
Burkittsville soils were formerly included with the Myersville and Fauquier soils in the 1960 Frederick County soil survey.
