GETAWAY SERIES

The Getaway series consists of deep, well drained soils formed in loess and colluvium from basalt, andesite, or andesitic basalt with an influence of volcanic ash mixed in the surface. Getaway soils are on mountain side slopes and canyon walls. Slopes are 15 to 90 percent. The mean annual precipitation is about 27 inches and the mean annual temperature is about 43 degrees F.

TAXONOMIC CLASS: Loamy-skeletal, isotic, frigid Vitrandic Argixerolls

TYPE LOCATION: Asotin County, Washington; about 4 miles west of Anatone; 350 feet south and 1,600 feet west of northeast corner of sec. 19, T. 8 N., R. 45 E.

RANGE IN CHARACTERISTICS: The solum thickness and depth to a lithic contact is 40 to more than 60 inches. The average annual soil temperature is 43 to 46 degrees F. The soils are usually moist, but are dry in all parts between depths of 4 and 12 inches for 45 to 75 consecutive days during summer and fall. The particle-size control section has by volume 35 to 60 percent angular basalt fragments and averages 25 to 35 percent clay.

The mollic epipedon is 20 to 35 inches thick. Reaction is moderately acid through neutral.

The A1 horizon has a value of 3 through 5 dry, 2 or 3 moist, and chroma of 1 through 3 dry or moist. It is stony or cobbly. Estimated volcanic glass content is 5 to 20 percent and acid-oxalate extractable Al plus 1/2 Fe - 0.4 to 0.8 percent.

The A2 horizon has a value of 4 or 5 dry, 2 or 3 moist, and chroma of 2 or 3 dry or moist. It is cobbly, very cobbly, or very gravelly. Estimated volcanic glass content is 5 to 20 percent and acid-oxalate extractable Al plus 1/2 Fe - 0.4 to 0.8 percent.

The Bt1 horizon has hue of 7.5YR or 10YR, value of 3 through 5 dry, 3 or 4 moist, and chroma of 2 to 4 dry or moist. It is very cobbly silty clay loam, very cobbly clay loam, or very gravelly loam with 20 to 35 percent clay.

The Bt2 and Bt3 horizons have hue of 5YR through 10YR, value of 4 or 5 dry, 3 or 4 moist, and chroma of 3 or 4 dry and 2 through 4 moist. It is very cobbly clay loam, extremely cobbly clay, or extremely gravelly clay loam with 27 to 45 percent clay.

COMPETING SERIES: These are Klicker, Klickson, Larabee, Millerflat, Stemilt, and Sycreek (T) series.

Klicker soils - mollic epipedon 10 to 20 inches thick; dry for 60 to 75 consecutive days following summer solstice; 20 to 40 inches to lithic bedrock (basalt)

Klickson soils - mollic epipedon 10 to 20 inches thick; dry for 45 to 60 consecutive days following summer solstice.

Larabee soils - mollic epipedon 10 to 20 inches thick; dry for 45 to 60 consecutive days following summer solstice; estimated acid-oxalate extractable Al plus 1/2 Fe - 0.8 to 1.5 percent in the surface layers; 20 to 40 inches to lithic bedrock (basalt).

Millerflat soils - dry for 45 to 60 consecutive days following summer solstice; greater than 60 inches to stratified gravelly and sandy alluvium; depth to redox depletions is 20 to 30 inches.

Stemilt soils - mollic epipedon 10 to 18 inches thick; dry for 60 to 75 consecutive days following summer solstice.

Sycreek soils - Mollic epipedon 10 to 15 inches thick; dry for 60 to 75 consecutive days following summer solstice; depth to 2CBd horizon (densic contact) is 30 to 45 inches.

GEOGRAPHIC SETTING: Getaway soils are on mountain side slopes and canyon walls and have slopes of 15 to 90 percent. These soils formed in loess and colluvium from basalt, andesite, or andesitic basalt with an influence of volcanic ash mixed in the surface. Elevation typically ranges from 2,800 to 5,000 feet but may range to 6,000 feet on south slopes. These soils are in a climate with warm, dry summers and cool, moist winters. The mean annual precipitation typically is 17 to 30 inches but may range to 40 inches in some areas. The average January temperature is about 27 degrees F. and the average July temperature is about 63 degrees F. The mean annual temperature is 42 to 45 degrees F. The frost-free period is 60 to 110 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Harlow, Cloverland, Snell, and Sweiting soils. Harlow and Snell soils are on canyon walls and Sweiting soils are on plateaus and all three soils have basalt at depths less than 40 inches. Cloverland soils are on plateaus and are fine-silty.

DRAINAGE AND PERMEABILITY: Well drained, medium to very rapid runoff, moderately slow permeability.

USE AND VEGETATION: These soils are used for timber production, livestock grazing, and wildlife habitat. Native vegetation is Douglas-fir and ponderosa pine, with an understory of pinegrass, common snowberry, and ninebark. The dominant USFS plant association is Douglas fir/ninebark, but ranges to Douglas fir/elk sedge and Ponderosa pine/common snowberry.

DISTRIBUTION AND EXTENT: Blue Mountains in southeastern Washington and northeastern Oregon; MLRA 9. The series is of moderate extent.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Portland, Oregon

SERIES ESTABLISHED: Asotin County, Washington, 1984.

REMARKS: Diagnostic horizons and features recognized in this pedon are:
Mollic epipedon - the zone from 1 to 31 inches
Argillic horizon - the zone from 16 to 59 inches
Ultic feature - assumed the base saturation is less than 75 percent in the upper 30 inches of the pedon
Vitrandic feature - the zone from 1 to 16 inches
Depths to diagnostic horizons and features are measured from the top of the first mineral layer.
