COMPETING SERIES: These are no competing series in this family.
GEOGRAPHIC SETTING: The Everett soils are on glacial outwash terraces and terrace escarpments at elevations of 30 to 700 feet. Slopes are 0 to 65 percent. These soils formed in alluvium or glacial outwash from granite, quartzite, shale, sandstone, schist, basalt, and andesite with an admixture of volcanic ash in the upper part. the climate is mild, summer is cool and dry, and winter is mild and wet. Mean annual precipitation ranges from 30 to 50 inches. Average January temperature is 36 degrees F., average July temperature is 63 degrees F., and the average annual temperature is 50 degrees F. The average frost-free season ranges from 145 to 240 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Alderwood, Baldhill, Indianola, and Kapowsin soils. Alderwood soils have a densic contact at a depth of 20 to 40 inches. Indianola soils are sandy throughout. Kapowsin soils are coarse-loamy. Baldhill soils are loamy-skeletal.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat excessively drained; high to very high saturated hydraulic conductivity.
USE AND VEGETATION: Some areas are used for pasture and others are cultivated and used for growing berries and small fruits. Some are used for homesites, sanitary landfills and as a source of sand and gravel. They now support second growth Douglas-fir and some red alder and western hemlock, with an understory of salal, Oregon-grape, vine maple, western brackenfern, red huckleberry, creambush oceanspray and trailing blackberry.
DISTRIBUTION AND EXTENT: Northwest Washington; MLRA A2, Northern part. Series is of large extent.
MLRA OFFICE RESPONSIBLE: Portland, Oregon
SERIES ESTABLISHED: 1910 Reconnaissance Survey of Eastern Puget Sound Basin, Washington.
REMARKS: Classification changed 4/94 and 1/00 because of amendments to Soil Taxonomy. Estimated content of volcanic glass of >5 percent and >0.4 percent Al + 1/2 Fe by acid-oxalate. Diagnostic horizons and features recognized in this pedon are an ochric epipedon and a cambic horizon from 2 to 19 inches.
