Lintonia silt loam occurs in several parts of the county
but is confined chiefly to the valley of Sugar River. The
largest tracts are in Clarno, Decatur, Broddyn, Albany,
Exeter, and Cadiz townships. The soil is developed on
stream terraces, and the surface is for the most part level
or has a gentle slope toward the stream along which it oc-
curs. It frequently occurs on narrow benches, varying in
width from a few rods to one-half mile, between the bottom
land subject to overflow and the steep slopes forming the
valley walls. The terraces are above present flood plains,
and the natural drainage is usually fair or good. However,
in places where the depth to sand is more than 3 feet and
the surface level, the natural drainage may be deficient.
Gullies and ravines have been cut across the terraces by
water rushing down the valley slopes. The material com-
posing Lintonia silt loam is largely of alluvial origin, al-
though it is probable that the surface material, especially
close to the foot of the bluffs, is partly colluvial, having been
washed down the steep slopes from areas of Knox silt loam
lying at higher elevations.
Although the surface soil is slightly acid in places, the
land nearest the bluffs is slightly calcareous, especially
where it occurs adjacent to uplands underlain by limestone
from which there is a wash.
