Piedmont areas small rounded diabase fragments occur on the surface.
Occasionally on steep slopes or high knobs the soil covering has been
washed away, leaving the heavy red clay exposed on the surface. These
areas, however, are small.

The type occurs principally in the intermediate valley of the Catoctin
Belt, between the Blue Ridge and the Catoctin Mountain, and on the
west slopes of the Catoctin Mountain. In the valley it occupies
several small, disconnected areas scattered throughout this region,
while on the west slope of the mountain it is found in one of two
long, broad areas, extending in a northeast and southwest direction.
Three small areas occur near the southeastern corner of the County,
and the type is here closely related to the Iredell clay loam.

The most typical areas of this soil occur in the Piedmont Plateau and
on the gentle slopes at the foot of the Blue Ridge in the vicinity of
Bluemont.

This soil type has excellent surface drainage and is well watered and
drained throughout by small streams. Few of the slopes are so steep as
to wash badly. The heavy clay subsoil retains ample moisture for plant
growth and the soil is rarely so wet as to necessitate tile draining,
although this would undoubtedly be very beneficial in the case of the
heavier phases.

The whole of this soil is under cultivation and it is highly esteemed
wherever found, being naturally a strong soil and susceptible of
improvement. The original forest growth consisted of oak, hickory, and
walnut. The land is easily improved, retentive of moisture and manure,
and with careful management makes an excellent soil for general
