The particle-size control section averages from 6 to 17 percent clay and from 55 to 80 percent fine sand or coarser. The base saturation (by sum of cations) is less than 60 percent in some part of the argillic horizon. Rock fragments are of mixed lithology and primarily of igneous origin and include no limestone or dolomite fragments. Volume of gravel ranges from 1 to 15 percent in the surface layer and from 5 to 35 percent in the subsoil and substratum. Volume of cobbles ranges from 0 to 5 percent and volume of stones range from 0 to 3 throughout. Surface stones have coverage ranging from 0 to 3 percent. Reaction typically ranges from very strongly acid to neutral in the solum. Reaction ranges from slightly acid to neutral in the substratum.
The A horizon has value of 2 or 3, and chroma of 1 or 2. Some pedons have an O horizon less than 3 inches thick. In cultivated areas, the Ap horizon has hue of 10YR, value of 3 or 4, and chroma of 2 or 3. Texture is sandy loam.
The E horizon has hue of 10YR or 7.5YR, value of 4 to 6, and chroma of 2 or 3. Texture is sandy loam, fine sandy loam, loam or the gravelly analogs.
Some pedons have Bw horizons with hue of 10YR or 7.5YR and value and chroma of 4 to 6. Texture is sandy loam, fine sandy loam, loamy sand, or the gravelly analogs.
Glendenning soils have a glossic horizon (E/B or B/E horizons, or both). The E part of the E/B and B/E horizons has colors like the E horizon described above.

COMPETING SERIES: These are the Brennyville, Fallcreek, Hatley, Magnor, Magroc, Mora, Oesterle, Plover, Rosy and Stinnett series. Brennyville soils have a silt loam mantle that ranges from 15 to 30 inches thick and a base saturation greater than 60 percent in all parts of the argillic horizon. Fallcreek soils do not have a densic contact. Hatley soils have a silt mantle 12 to 40 inches thick and do not have a densic contact. Magnor soils have a silt loam mantle from 12 to 36 inches thick. Magroc soils have a lithic contact at depths of 40 to 60 inches. Mora soils have a base saturation greater than 60 percent in all parts of the argillic horizon and a densic contact at 40 to 60 inches. Plover soils have less than 5 percent coarse fragments throughout and have stratified fine sand, very fine sandy loam, fine sandy loam, sandy loam, and/or silt loam in the lower part of the series control section. Oesterle soils have sand and gravel below 40 inches. Rosy soils have free carbonates at depths of 30 to 60 inches. Stinnett soils have a densic contact with sandy glacial till at depths of 40 to 60 inches.
GEOGRAPHIC SETTING: These soils formed in sandy loam till or mudflow sediments of Late Wisconsinan Age. Slope ranges from 0 to 4 percent. Mean annual air temperature ranges from 39 to 45 degrees F. Mean annual precipitation ranges from 28 to 33 inches. Frost-free days range from 120 to 135. Elevation above sea level ranges from 950 to 1400 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These are Amery, Capitola, Freeon, Haugen, and Magnor soils. The well drained Amery, moderately well drained Haugen, and very poorly drained Capitola soils are in a drainage sequence with Glendenning soils. Amery and Haugen soils are on more sloping or higher positions. Capitola soils are in depressions or drainageways. The moderately well drained Freeon soils and the somewhat poorly drained Magnor soils form a drainage sequence in nearby areas where there is a silty mantle 12 to 35 inches thick.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained. Runoff is low. Permeability is moderate in the upper part of the solum, moderately slow in the lower part of the solum, and very slow in the substratum. This soil has a seasonal high perched zone of saturation at depths as high as .5 foot in April to June in normal years.
USE AND VEGETATION: Most areas of this soil forested. The most common trees are northern red oak, white oak, white ash, American basswood, quaking aspen, sugar maple, and white pine. Approximately one third of this soil is cultivated. Commonly grown crops are corn, oats, and hay.
DISTRIBUTION AND EXTENT: Northwestern Wisconsin. LRR K and MLRA 90A. This soil is of small extent.
