(0 to 3 inches thick)
Bw1--10 to 18 inches; dark brown (10YR 3/3) silt loam, brown (10YR 5/3) dry; weak coarse prismatic structure parting to weak medium subangular blocky structure; slightly hard, friable, slightly sticky and slightly plastic; many very fine roots; many very fine and fine tubular pores; neutral (pH 7.0); clear smooth boundary. (8 to 14 inches thick)

TYPE LOCATION: Sherman County, Oregon; 1/8 mile north of section line, 0.1 mile in field from gate at county road, 0.5 mile by county road from U. S. Highway 97, SE1/4 SW1/4 sec. 3, T. 1 S., R. 17 E.
RANGE IN CHARACTERISTICS: In most years the soil is usually moist but is dry throughout between depths of 4 and 12 inches for 60 to 90 consecutive days within the 4-month period following the summer solstice. The mean annual soil temperature is 51 to 56 degrees F. Thickness of the solum and depth to bedrock is 20 to 40 inches.
The A horizon has value of 4 or 5 dry and 2 or 3 moist and chroma of 2 or 3 moist and dry.
The B horizon has value of 5 or 6 dry. It is silt loam and has 10 to 17 percent clay and less than 15 percent coarser than very fine sand. This horizon has weak to moderate subangular blocky or prismatic structure.
COMPETING SERIES: These are the Lakesol and Walla Walla series. Lakesol and Walla Walla soils are deeper than 40 inches to bedrock and Lakesol soils are underlain by lacustrine sediments.
GEOGRAPHIC SETTING: The Anderly soils are on uplands at elevations of 300 to 2,500 feet. Slopes are 1 to 35 percent. The soils formed in loess mixed with a small amount of volcanic ash overlying basalt. The climate is semiarid with moist winters and dry summers. The mean winter temperature is 35 to 38 degrees F., mean summer temperature is 64 to 66 degrees F., and mean annual temperature is 49 to 54 degrees F. Precipitation is 11 to 14 inches. The frost-free season is 150 to 170 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bakeoven, Lickskillet, Nansene and Wrentham soils and the competing Walla Walla soils. Bakeoven and Lickskillet soils contain more than 35 percent rock fragments and are less than 20 inches deep to bedrock. Nansene soils are on steep north slopes and are more than 40 inches deep to bedrock. Wrentham soils are on steep north slopes and are loamy-skeletal.
DRAINAGE AND PERMEABILITY: Well drained; slow to rapid runoff; moderate permeability.
USE AND VEGETATION: Principal use is for grain crops. Other uses are hay, pasture and native range. Vegetation is mainly bunchgrasses, forbs and shrubs.
DISTRIBUTION AND EXTENT: North-central Oregon. This series is of moderate extent.
