<br />Range in Characteristics
<br />Note: These soils are in the sandy, sandy-skeletal,
<br />coarse-loamy, fine-loamy, fine-loamy over sandy
<br />or sandy-skeletal, fine, or clayey over sandy or
<br />sandy-skeletal particle-size families. The water
<br />table is at or near the surface during the spring
<br />and early summer. In some areas the water table
<br />remains above a depth of 1 foot throughout the
<br />year, while in other areas the water table is at a
<br />depth of 1 foot to 3 feet during late summer, fall,
<br />and winter.
