(0 to 3 inches thick)
A3g--4 to 8 inches; dark grayish brown (2.5Y 4/2) silt loam, light brownish gray (2.5Y 6/2) dry; common fine distinct dark yellowish brown (10YR 4/4) mottles; weak medium granular structure; slightly hard, friable, nonsticky and slightly plastic; common fine roots; violently effervescent; strongly alkaline (pH 8.6); clear wavy boundary. (3 to 4 inches thick)
B2g--8 to 18 inches; grayish brown (10YR 5/2) silt loam, light gray (10YR 7/2) moist; common medium distinct yellowish brown (10YR 5/4) mottles; weak medium subangular blocky structure; slightly hard, friable, nonsticky and slightly plastic; few roots; few tubular pores; slightly effervescent; moderately alkaline (pH 8.4); gradual wavy boundary. (0 to 15 inches thick)

TYPE LOCATION: Yakima County, Washington; 740 feet east and 40 feet north of the center of section 24, T.10N., R.21E.
RANGE IN CHARACTERISTICS: These soils are always moist. The high water table is between depths of 2 and 40 inches. Effervescence is none to violent in any one horizon. Sodium saturation is 15 percent or more in the upper 25 to 50 cm and decreases with increasing depth. The mean annual soil temperature is estimated to be 52 degrees F. at a depth of 20 inches. The 10 to 40 inch control section has less than 15 percent sand coarser than very fine and 5 to 10 percent clay. Colors are in the 2.5Y or 10YR hue.
The Ap horizon has value of 2 or 3 moist, 4 or 5 dry.
The Ag horizon has value of 3 or 4 moist, 5 or 6 dry. Mottles have value of 4 or 5.
The Bg horizon has value of 3, 4 or 5 moist and 5, 6 or 7 dry. The mottles have value of 4 or 5. This horizon is silt loam or very fine sandy loam. This horizon is moderately alkaline or strongly alkaline. Some pedons lack a Bg horizon.
The C horizon has value of 3, 4 or 5 moist, 5, 6 or 7 dry, and chroma of 3 or 4 moist and dry. The mottles have value of 4 or 5. This horizon is silt loam or very fine sandy loam. It is moderately alkaline or strongly alkaline.
COMPETING SERIES: This is the Sinloc series in another family. Sinloc soils have a chroma of 1 or 2 throughout the control section.
GEOGRAPHIC SETTING: Outlook soils are on alluvial plains. Slopes are 0 to 3 percent. Elevations are 300 to 2,000 feet. These soils formed in silty alluvium. Outlook soils are in a semiarid climate having an annual precipitation of 6 to 12 inches and warm, dry summers and cool, moist winters. The average January temperature is 29 degrees F.; the average July temperature is 73 degrees F.; and the mean temperature is 51 degrees F. The frost free season is 130 to 160 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Esquatzel and Shano soils and the competing Sinloc soils. Esquatzel and Shano soils are well drained and lack sodic properties.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained; very slow to slow runoff; moderate permeability.
USE AND VEGETATION: Mainly native pasture. Native vegetation is inland saltgrass, basin wildrye, black greasewood, and other halophytic plants.
DISTRIBUTION AND EXTENT: Central Washington. These soils are of small extent.
MLRA OFFICE RESPONSIBLE: Portland, Oregon
SERIES ESTABLISHED: Yakima County, Washington, 1979.
REMARKS: The Outlook soils were formerly included with soils mapped as Esquatzel.
