RANGE IN CHARACTERISTICS: The soils are usually moist but are dry between depths of 4 and 12 inches for 60 to 80 consecutive days during the summer. The mean annual soil temperature is 50 degrees to 54 degrees F. The solum is 15 to 25 inches thick. Reaction is slightly acid or neutral.
The A horizon has hue of 10YR or 7.5YR, value of 4 or 5 dry, 2 or 3 moist and chroma of 2 or 3 moist and dry. Texture is fine sandy loam, sandy loam or coarse sandy loam.
The Bw horizon has hue of 7.5YR or 10YR, value of 4 or 5 dry, 2 or 3 moist and chroma of 2 or 3 moist and dry. Texture is fine sandy loam, sandy loam or coarse sandy loam. Rock fragments (2mm to 25mm in diameter) in the solum range from 0 to 25 percent. It has weak coarse prismatic or weak coarse subangular blocky structure.
The C horizon has hue of 7.5YR or 10YR, value of 5 or 6 dry, 3 or 4 moist and chroma of 3 or 4. Texture is fine sandy loam, sandy loam, loamy fine sand or sand. Rock fragments (2mm to 25mm in diameter) range from 0 to 35 percent. Below depths of about 30 to 40 inches the C horizon is loamy fine sand, loamy sand, loamy coarse sand or sand.

GEOGRAPHIC SETTING: Wind River soils are on terraces and terrace escarpments. Slopes are 0 to 30 percent. The soils formed in moderately coarse and coarse textured old alluvium or outwash. Elevations are 100 to 800 feet. The climate is characterized by cool wet winters and hot dry summers. The mean annual precipitation is 18 to 40 inches. The average July temperature is 66 degrees F. and the average January temperature is 33 degrees F. The mean annual temperature is 48 to 52 degrees F. The frost-free period is 150 to 180 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Rockford and Van horn soils. Rockford soils contain more than 50 percent rock fragments. Van horn soils have B2 horizons of sandy clay loam with 27 to 35 percent clay. These soils are on uplands.
DRAINAGE AND PERMEABILITY: Well-drained; moderately rapid permeability.
USE AND VEGETATION: These soils are used dominantly for growing tree fruits. Other uses are growing strawberries, truck crops, hay, and pasture. Native vegetation is mainly Douglas-fir, grand fir, ponderosa pine, and Oregon white oak.
DISTRIBUTION AND EXTENT: North-central Oregon and southwestern Washington; MLRA 6. The soils are inextensive.
