Dellwood soil and landscape
Soil profile: The very deep, moderately well drained Dellwood soils are sandy in the upper part of the profile and sandy-skeletal in the lower part. (Soil Survey of Yancey County, North Carolina; by Bruce P. Smith, Jr., Natural Resources Conservation Service)
Landscape: Dellwood soils are on nearly level and gently sloping flood plains of fast flowing streams in the upper reaches of watersheds in the Southern Appalachian Mountains. Elevation generally ranges from about 1,200 to 3,200 feet, but many range as high as 4,500 feet. The soils formed in loamy and sandy alluvium that contains a large amount of rounded gravel and cobbles.
Dellwood-Reddies complex, 0 to 3 percent slopes, occasionally flooded
Setting
Landscape: Mountain valleys
Elevation range: 2,000 to 3,000 feet
Landform: Flood plains dominantly at the upper end of mountain valleys
Landform position: Planar to slightly convex
bottomland slopes
Shape of areas: Long and narrow
Size of areas: As much as 329 acres
Composition
Dellwood soil and similar inclusions: 45 percent
Reddies soil and similar inclusions: 35 percent
Dissimilar inclusions: 20 percent
Typical Profile--Dellwood
Surface layer:
0 to 4 inches—very dark grayish brown loamy fine sand
4 to 15 inches—dark brown loamy fine sand
Underlying material:
15 to 67 inches—multicolored very gravelly coarse sand
TAXONOMIC CLASS: Sandy-skeletal, mixed, mesic Oxyaquic Humudepts
Depth class: Very deep
Drainage class: Moderately well drained
General texture class: Dellwood—sandy in the upper part of the profile and sandy-skeletal in the lower part; Reddies—sandy in the upper part of the profile and sandy or sandy-skeletal in the lower part
Permeability: Dellwood—moderately rapid in the surface layer and rapid or very rapid in the underlying material; Reddies—moderately rapid in the surface layer and subsoil and rapid in the underlying material
Available water capacity: Very low
Depth to seasonal high water table: Dellwood—2.0 to 4.0 feet from December through May; Reddies—
2.0 to 3.5 feet from December through May
Hazard of flooding: Occasional, throughout the year with standing water for less than 2 days
Shrink-swell potential: Low
Slope class: Nearly level or gently sloping
Extent of erosion: Slight, less than 25 percent of the original surface layer has been removed
Hazard of water erosion: None or slight
Organic matter content (surface layer): Moderate or high
Potential frost action: Low
Special climatic conditions: Soils subject to slow air drainage, which allows late spring and early fall frosts
Soil reaction: Very strongly acid to neutral throughout the profile
Parent material: Alluvium derived from felsic or mafic, high-grade metamorphic or igneous rock
Depth to bedrock: More than 60 inches
Depth to contrasting material: Dellwood—8 to 20 inches to deposits of cobbles and gravel that are
stratified with sandy or loamy material; Reddies—20 to 40 inches to deposits of cobbles and gravel
that are stratified with sandy or loamy material
Other distinctive properties: Soils subject to scouring and deposition during flooding
