138 Soil Survey of
3C horizon:
Hue—7.5YR or 10YR
Value—3 to 6
Chroma—3 to 6
Texture—the gravelly, very gravelly, or extremely
gravelly analogs of sand, loamy sand, sandy
loam, coarse sand, loamy coarse sand, or
coarse sandy loam
Content of gravel—15 to 70 percent
369A—Waupecan silt loam, 0 to 2 percent
slopes
Setting
Landform: Outwash plains, stream terraces, and
kames
Position on the landform: Summits
Slope range: 0 to 2 percent
A typical soil series description with range in
characteristics is included, in alphabetical order, in this
section. Additional information specific to this map
unit, such as horizon depth and textures, is available
in the “Soil Properties” section in Part II of this
publication.
Composition
Waupecan and similar soils: 85 percent
Dissimilar soils: 15 percent
Similar soils:
• soils that contain sandy and gravelly deposits at a
depth of less than 40 inches or more than 60 inches
• soils that have a seasonal high water table at a
depth of less than 6 feet
• soils that have no subsurface layer
Dissimilar soils:
• the somewhat poorly drained Grundelein and
Millstream soils in the lower positions on the landform
• the poorly drained Dunham soils in depressions and
drainageways
Management

369B—Waupecan silt loam, 2 to 4 percent
slopes
Setting

kames
Position on the landform: Summits, shoulders, and
backslopes
Slope range: 2 to 4 percent
