TYPE LOCATION: Coos County, Oregon; 3 miles south of Charleston on the east side of a log trail off a log road, north of Seven Devils Road; 2,300 feet south, 1,450 feet west of the NE corner of section 22, T. 26 S., R. 12 W.
RANGE IN CHARACTERISTICS: The soil is usually saturated above the Bs horizon during the winter and spring. The mean annual soil temperature is 50 to 54 degrees F. The difference between mean summer and mean winter soil temperature varies from 5 to 9 degrees F. Depth of rooting and downward water movement is restricted by the thin lenses of ortstein in the Bs horizon and by the very firm 2C horizon. Depth to bedrock is greater than 60 inches.
An A horizon, in some pedons, has hue of 10YR or 7.5YR, value of 2 or 3 moist, chroma of 2 or 3, and is up to 4 inches in thickness. It is silt loam or very fine sandy loam, is very high in organic matter and has many roots.
The E horizon has value of 5 to 7 moist, 6 to 8 dry, and chroma of 0 to 2. It commonly is very fine sandy loam, but ranges to silt loam or loam.
The Bh horizon has hue of 5YR to 10YR, value of 2 or 3 moist, 4 or 5 dry, and chroma of 1 or 2. It is loam, silt loam, fine sandy loam, or sandy loam and high in organic matter and fibrous roots.
The Bs horizon has hue of 5YR to 2.5Y, value of 4 to 6 moist, 5 to 7 dry, and chroma mainly of 4 to 8 moist and dry with streaks of 1 to 4 occurring randomly throughout. The ratio of free iron to carbon ranges from 1.0 to 4.0. It is massive or platy and is weakly or strongly cemented.
The 2C horizon has hue of 7.5YR to 5Y, value of 4 to 7 moist , 6 to 8 dry and chroma of 2 to 6 moist and dry. It has few to many distinct or prominent redox concentrations and is mottled. It is weathered from siltstone or marine sediments and is silt loam, silty clay loam, or loam, usually thinly to thickly stratified. Below a depth of 40 inches texture ranges to sandy loam and clay loam.
COMPETING SERIES: This is the Depoe series. Depoe soils have an umbric epipedon when mixed to a depth of 10 inches.
GEOGRAPHIC SETTING: Joeney soils are on old marine terraces at elevations of 150 to 550 feet. Slopes are 0 to 7 percent. The soils formed in medium textured eolian materials overlying stratified marine deposits on wave eroded surfaces. The soils are usually on flats or in slight depressions. The marine climate is cool and wet in the winter and cool and moist during the summer with fog. The mean annual precipitation is 50 to 90 inches. The mean annual temperature is 50 to 53 degrees F. The mean January temperature is 42 to 45 degrees F., and mean July temperature is 59 to 62 degrees F. The frost-free period is 190 to 300 days. The Joeney soils occur on the Seven Devils geomorphic surface.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bandon, Bullards, Blacklock, and Cunniff soils. Bandon and Bullards soils are coarse-loamy and are well drained. Also, Bullards soils lack ortstein. Blacklock soils are sandy. Cunniff soils are well drained and have an argillic horizon.
DRAINAGE AND PERMEABILITY: Poorly drained; moderate permeability in the upper part of the solum, very slow permeability in the cemented pan, and moderately slow in the substratum. A perched water table fluctuates between the soil surface and a depth of 1.5 feet from November to March.
USE AND VEGETATION: These soils are used for timber production, pasture, specialty crops, wildlife, and a few homesites. The native vegetation is Sitka spruce, western redcedar, western hemlock, occasional Douglas fir, Port Orford cedar, evergreen huckleberry, Pacific rhododendron, salal, king's gentian, sedges, rushes, and water tolerant grasses.
DISTRIBUTION AND EXTENT: Old marine terraces of south-central Oregon coast; MLRA 1. The series is inextensive.
