LOCATION JUNO WAEstablished Series
TAXONOMIC CLASS: Sandy-skeletal, mixed, mesic Typic Udifluvents
TYPICAL PEDON: Juno sandy loamy-brushland. (Colors are for moist soil unless otherwise noted.)
A1--0 to 16 inches; dark brown (10YR 3/3) sandy loam, light brownish gray (10YR 6/2) dry; single grained; loose, nonsticky and nonplastic; 10 percent pebbles; many fine roots; medium acid (pH 5.6); clear smooth boundary.
IIC--16 to 60 inches; multicolored extremely gravelly sand; single grained, loose; 70 percent pebbles; medium acid (pH 5.8).
TYPE LOCATION: Mason County, Washington; 1 mile east of Satsop State Park; between county road and East Fork Satsop River; SW corner sec. 28, T.19N., R.6W., W.M.
RANGE IN CHARACTERISTICS: The solum is 10 to 20 inches thick. The mean annual soil temperature is 47 degrees to 53 degrees F.
The A horizon has hue of 7.5YR or 10YR, value of 3 or 4 moist and chroma of 2 or 3. Gravel content ranges from 10 to 35 percent. It is strongly acid or medium acid.
The IIC horizon is very gravelly sand or extremely gravelly sand. It is slightly acid or medium acid.
COMPETING SERIES: These are the Huel and Humptulips series. Huel soils have 2.5Y or 5Y hue. Humptulips soils have a coarse-loamy over sandy or sandy-skeletal control section.
GEOGRAPHIC SETTING: Juno soils are on alluvial bottoms at elevations of 10 to 300 feet. Slopes are 0 to 3 percent. These soils formed in alluvium from glacial sediments. Annual precipitation is 70 to 100 inches. Mean January temperature is about 38 degrees F.; mean July temperature is about 62 degrees F. The frost-free season is 130 to 170 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Belfast and the competing Humptulips soils. Belfast soils have a coarse-loamy control section.
DRAINAGE AND PERMEABILITY: Somewhat excessively drained; slow runoff; rapid permeability. Juno soils are subject to stream overflow.
USE AND VEGETATION: Native vegetation is mainly spruce, red alder, western hemlock and an understory of salal, huckleberry, blackberry, grasses and forbs.
DISTRIBUTION AND EXTENT: Western Washington; series is of small extent.
