TYPE LOCATION: Klickitat County, Washington, about 2 1/2 miles northwest of Maryhill, WA about 1,800 feet west and 1,000 feet north of the southeast corner of section 31, T. 3 N., R. 16 E.; (Latitude 45 degrees, 41 minutes, 47 seconds N. and Longitude 120 degrees, 50 minutes, 58 seconds W.)
RANGE IN CHARACTERISTICS: The mean annual soil temperature is 48 to 52 degrees F. These soils are usually moist, but are dry in all parts between depths of 8 and 25 inches for 90 to 105 consecutive days. Depth to bedrock is 20 to 40 inches. The particle-size control section contains 35 to 75 percent rock fragments, 18 to 27 percent clay, and 0 to 2 percent calcium carbonate equivalent. The mollic epipedon is 7 to 14 inches thick.
The A horizon has a hue of 10YR or 7.5YR, value of 4 or 5 dry and chroma of 2 to 4 dry, 2 or 3 moist. Reaction is slightly acid to slightly alkaline.
The ABt horizon has a hue of 10YR or 7.5YR and chroma of 3 or 4 dry and moist. Texture is very gravelly loam or very stony loam. Reaction is slightly alkaline or moderately alkaline.
The Bt horizon has a hue of 10YR or 7.5YR, value of 4 or 5 dry and moist and chroma of 3 or 4 dry and moist. Texture is very cobbly loam, very gravelly loam, or extremely cobbly loam. Reaction is slightly alkaline or moderately alkaline.
The BCt horizon has a hue of 10YR or 7.5YR, value of 4 or 5 dry and moist and chroma of 3 or 4 dry and moist. Texture is extremely stony loam, extremely gravelly loam, or very gravelly silt loam. Reaction is slightly alkaline or moderately alkaline.

GEOGRAPHIC SETTING: Goodnoe soils are on hillslopes and canyon walls and have slopes of 30 to 65 percent. These soils formed in colluvium and residuum from basalt mixed with minor amounts of loess. Elevations are 500 to 2,800 feet. Summers are warm and dry and winters are cool and moist. The mean annual precipitation is 9 to 15 inches. The average January temperature is 29 degrees F. and average July temperature is 67 degrees F. The mean annual temperature is 46 to 50 degrees F. The frost-free season is 120 to 165 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Horseflat, Tronsen, Swalecreek and Walla Walla soils. Horseflat soils are on upper side slopes and ridges, and are 14 to 20 inches to bedrock. Tronsen soils are on benches, are clayey-skeletal, and are more than 60 inches to bedrock. Swalecreek soils are on escarpments, swales, and benches, are fine-loamy, and are more than 60 inches to bedrock. Walla Walla soils are on side slopes and hills, are coarse-silty, and are more than 60 inches to bedrock.
DRAINAGE AND PERMEABILITY: Well drained; very rapid runoff; moderate permeability.
USE AND VEGETATION: These soils are used mainly for livestock grazing. Native vegetation is mainly bluebunch wheatgrass, Sandberg bluegrass, and cusick bluegrass.
DISTRIBUTION AND EXTENT: Klickitat County, Washington; MLRA 8. The series is of small extent.
