TYPE LOCATION: Clallam County, Washington; 600 feet north and 1,600 feet west of the southeast corner of section 36, T. 30 N., R. 3 W.
RANGE IN CHARACTERISTICS: The particle-size control section contains 0 to 10 percent rock fragments. The mean annual soil temperature is estimated to range from 51 degrees to 53 degrees F., and the mean summer temperature from 58 degrees to 62 degrees F. The soil is dry in the moisture control section for 60 to 75 consecutive days following summer solstice.
The E horizon has hue of 10YR or 2.5Y, value of 4 through 6 moist, 6 or 7 dry, and chroma of 1 through 4. It is loamy sand, fine sand, or medium sand. This horizon has subangular blocky or granular structure. It is neutral to moderately acid.
The E&B horizon has hue of 10YR or 2.5Y, value of 4 through 6 moist, 6 or 7 dry, and chroma of 2 through 6. This horizon above 40 inches is fine sand, sand, or loamy sand. Below 40 inches, this horizon ranges to gravelly sand or gravelly loamy sand. It is slightly acid or neutral. Total thickness of lamellae is less than 6 inches.
COMPETING SERIES: This is the Marble series. Marble soils lack E horizons are dry for 75 to 90 days following the summer solstice and the mean January soil temperature is 27 degrees F., and the mean summer soil temperature is 67 degrees F.
GEOGRAPHIC SETTING: Dick soils are on outwash plains at elevations near sea level to 500 feet. Slopes are 0 to 30 percent. They formed in glacial outwash. Dick soils are in a mild marine climate and have cool dry summers and cool moist winters. Mean January temperature is about 39 degrees F., mean July temperature is about 60 degrees F., and the mean annual temperature is about 50 degrees F. Mean annual precipitation is 17 to 25 inches. Frost-free season is 160 to 200 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Agnew, Cassolary, Clallam, Everett, and Indianola soils. Agnew and Cassolary soils are fine-loamy. Clallam soils are loamy-skeletal and have a densic contact between 20 and 40 inches. Everett soils are sandy-skeletal. Indianola soils lack lamellae.
DRAINAGE AND PERMEABILITY: Somewhat excessively drained; slow runoff; rapid permeability.
USE AND VEGETATION: Timber production, cropland, and homesites are the principal uses. Native vegetation is Douglas-fir, western hemlock, western redcedar, grand fir and red alder. Understory species include salal, red huckleberry, elderberry, bedstraw, evergreen huckleberry, oceanspray, Oregon grape, western swordfern, and brackenfern. Crops include hay, barley, strawberries, raspberries, green peas, mint oil, and pasture.
DISTRIBUTION AND EXTENT: Northwest Washington. This series is moderately extensive.
