TYPE LOCATION: Jackson County, Oregon; about 2 miles east of
Battle Mountain; approximately 2,340 feet east and 1,510 feet
south of the northwest corner of sec. 5, T. 34 S., R. 3 W.
RANGE IN CHARACTERISTICS: These soils are usually moist but are
dry in the moisture control section for 60 to 90 consecutive days
or more in the four months that follow the summer solstice. The
mean annual soil temperature is 47 to 54 degrees F. The particle-size control section averages 18 to 27 percent clay, 0
to 10 percent soft gravel and less than 15 percent coarser than
very fine sand. The base saturation is 40 to 60 percent by
ammonium acetate throughout the upper 20 inches of the solum.
The A horizon has hue of 10YR, 2.5Y, or 5Y, value of 3 or 4 moist
and 4 through 6 dry, and chroma of 2 or 3 moist and dry.
The Bt horizon has hue of 2.5Y or 5Y, value of 4 or 5 moist and 5
or 6 dry, and chroma of 2 or 3 moist and 2 through 4 dry.
COMPETING SERIES: There are no other series in this family.
GEOGRAPHIC SETTING: The Goolaway series consists of moderately
deep, well drained soils on mountains. These soils formed in colluvium derived from schist. Elevations are 1,500 to 4,000
feet. The climate is characterized by warm wet winters and hot
dry summers. The mean annual precipitation is 40 to 60 inches.
The mean annual temperature is 45 to 54 degrees F. The
frost-free period is 100 to 160 days. Slopes range from 12 to 50 percent.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Beekman,
Colestine,
Lettia,
Musty,
Pollard and
Siskiyou soils. Beekman
and Musty soils are loamy-skeletal. Colestine and Lettia soils
are fine-loamy and have hues of 10YR and 7.5YR. Siskiyou soils
are coarse-loamy. Pollard soils are fine.
DRAINAGE AND PERMEABILITY: Well drained; medium to rapid runoff; moderate permeability.
USE AND VEGETATION: These soils are used for timber production. Native vegetation is Douglas fir, sugar pine, incense cedar,
canyon live oak, common snowberry, and deerfoot vanillaleaf.
DISTRIBUTION AND EXTENT: Southwestern Oregon. The series is inextensive.
