TYPE LOCATION: Klickitat County, Washington; about 4 miles south of Glenwood, 1,000 feet north and 2,000 feet west of the southeast corner of section 34, T. 6 N., R. 12 E.
RANGE IN CHARACTERISTICS: These soils are usually moist, but are dry in the moisture control section for 45 to 60 consecutive days. The mean annual soil temperature is 47 to 49 degrees F. The particle-size control section averages 5 to 15 percent rock fragments. The upper 9 to 14 inches has 5 to 10 percent volcanic glass and acid oxalate extractable aluminum plus one-half iron of 0.4 to 1.0 percent. The solum is 40 to 60 inches thick.
The A horizon has hue of 5YR 10YR, value of 4 or 5 dry and chroma of 2 or 3 moist.
The Bw horizon has hue of 7.5YR or 10YR, value of 4 to 6 dry, 3 or 4 moist and chroma of 2 to 4 dry and moist. Texture is sandy loam or loam. Reaction is moderately acid or slightly acid.
The C horizon has hue of 7.5YR or 10YR, value of 4 to 7 dry, 3 or 4 moist and chroma of 2 to 4 dry and moist. Redox concentrations have hue of 5YR to 10YR, value of 5 to 7 dry, 4 to 6 moist and chroma of 4 to 6 dry and moist. Texture is sandy loam, loam, or sandy clay loam. Reaction is moderately acid to neutral.
COMPETING SERIES: This is the Conconully, Deno (T), Phoebe, Safety, Stevens and Uhlig series. Conconully soils are 20 to 40 inches to a dense glacial till 2 Cd layer and are dry for 90 to 105 consecutive days. Deno soils are 40 to 60 inches to a lithic contact and are dry for 60 to 90 consecutive days. Phoebe soils are dry for 60 to 90 consecutive days
GEOGRAPHIC SETTING: Fanal soils are on toe slopes at elevations of 1,800 to 2,500 feet. They formed in alluvium and colluvium from basalt with an influence of volcanic ash in the upper part. Summers are warm and dry, winters are cool and wet with an intermittent snow cover from December through March. The mean annual precipitation is 30 to 40 inches. The average January temperature is 27 degrees F. and the average July temperature is 66 degrees F. The mean annual temperature is 44 to 48 degrees F. The frost-free season is 60 to 90 days, but a damaging frost can occur any month of the year.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Conboy, Grayland, Kaiders, McGowan, Para, and Tigit soils. Kaiders soils are loamy-skeletal. Conboy and Grayland soils have an aquic moisture regime. McGowan, Para, and Tigit soils have an argillic horizon.
DRAINAGE AND PERMEABILITY: Moderately well drained; slow to medium runoff; moderate permeability. A seasonal water table is as high as 3 to 5 feet from January through March.
USE AND VEGETATION: This soil is used mainly for pasture and some is used for timber production. Introduced species used for pasture are tall fescue and bulbous bluegrass. Native vegetation is mainly ponderosa pine and some Douglas-fir and Oregon white oak, with an understory of common snowberry, woods rose, Canada bluegrass, tufted hairgrass, and spirea.
DISTRIBUTION AND EXTENT: Klickitat County, Washington; MLRA 6. The series is of small extent.
