(Soil Mapping Unit 4)

Parent materials for soils of unit 4 are represented by a wide variety
of materials. Bottomland and stream terrace soils have formed in
mixed alluvial deposits. Large areas of wind blown loamy and silty
materials. along with gravelly and cobbly outwash, exist within the
unit delineations. They are more widespread here than in the other
8 units shown on the general soil map. At many places loamy and
gravelly materials mantle residual clayey shales to depths of 4 to 10
feet. Shales where not covered have also furnished residual and
reworked parent materials.
