TYPE LOCATION: Whatcom County, Washington; about 4 miles north of Ferndale; 2,400 feet north and 1,500 feet west of the southeast corner of sec. 6, T. 39 N., R. 2 E.
RANGE IN CHARACTERISTICS: Mean annual soil temperature is 50 to 54 degrees F. Depth to the strongly cemented ortstein pan is 10 to 14 inches.
The Ap horizon has hue of 7.5YR or 10YR, value of 3 or 4 moist, 6 or 7 dry, and chroma of 1 through 3 moist and dry. Reaction is strongly acid or moderately acid. Pedons in uncultivated areas have an A horizon 3 to 7 inches thick similar to the Ap horizon.
The E horizon has hue of 7.5YR or 10YR, value of 3 through 5 moist, 6 or 7 dry, and chroma of 1 or 2 moist and dry. It is loam or sandy loam. Reaction is strongly acid or moderately acid.
The 2Bsm1 horizon has hue of 7.5YR or 10YR, value of 3 through 5 moist, 5 through 7 dry, and chroma of 2 through 4 moist and dry. It is a strongly cemented or indurated ortstein pan that breaks to loamy sand or sand. Reaction is moderately acid or slightly acid. Consistence is very hard or extremely hard when dry and very firm, or extremely firm when moist.
The 2Bsm2 horizon has hue of 7.5YR or 10YR, value of 3 through 5 moist, 5 through 7 dry, and chroma of 2 through 4 moist and dry. It is continuously weakly cemented with slightly hard to hard dry consistence. It breaks to loamy sand or sand. Reaction is moderately acid or slightly acid. Some pedons have a 2Bs horizon that has 15 to 35 percent ortstein concretions 1/4 to 2 inches in diameter having consistence of slightly hard to hard when dry.
The 2C horizon has hue of 10YR, 2.5Y, or 5Y, value of 3 or 4 moist, 6 or 7 dry, and chroma of 2 or 3 moist and dry. It is coarse sand or sand. Reaction is moderately acid or slightly acid.
COMPETING SERIES: These are the Custer, Edmonds, and Segidal series in other families These soils are more than 14 inches deep. Custer and Edmonds soils lack a continuously cemented pan.
GEOGRAPHIC SETTING: Woodlyn soils are on outwash terraces and outwash plains at elevations of 50 to 300 feet. Slopes are 0 to 2 percent. The soil formed in loess, volcanic ash and glacial outwash. Woodlyn soils are in a marine climate with warm dry summers and cool moist winters. Snow cover is intermittent. The average annual precipitation is 35 to 55 inches, which falls mostly between October and May. Each of the summer months has at least one inch of rainfall. Mean January temperature is 36 degrees F; mean July temperature is 62 degrees F; and the mean annual temperature is 50 degrees F. The frost-free season is 150 to 190 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Edmonds soils and the Everson, Fishtrap, Hale, Laxton, Lynden, Lynnwood, Pangborn, and Tromp soils. All of these soils lack a strongly cemented orstein pan. Everson soils are clayey over sandy or sandy-skeletal. Fishtrap and Pangborn soils are Histosols. Hale, Laxton, Lynden, and Tromp soils have a xeric moisture regime. Lynnwood soils have a xeric moisture regime and are sandy.
DRAINAGE AND PERMEABILITY: Poorly drained; very slow runoff; moderate permeability above the indurated pan, very slow within the pan, very rapid below. A perched water table is as high as 0 to 1 foot at times from November through April unless drained.
USE AND VEGETATION: Most areas are drained and used for cropland. Hay and pasture and corn silage are common crops. Some is used for woodland. Native vegetation is red alder, western hemlock, western redcedar, bigleaf maple, paper birch, and black cottonwood with an understory of vine maple, salmonberry, red huckleberry, western swordfern, and salal.
DISTRIBUTION AND EXTENT: Northwestern Washington. The series is of small extent.

REMARKS: This draft reflects a change in classification from medial, mesic, shallow, ortstein Typic Sideraquods to loamy, mixed, mesic, shallow, ortstein Typic Sideraquods. Diagnostic horizons and features recognized in this pedon are an ochric epipedon from 0 to 9 inches, an albic horizon from 9 to 12 inches and a cemented spodic horizon from 12 to 25 inches. These soils were sampled for characterization as the Drayton series. Laboratory Number S81WA-073-10.
