TYPE LOCATION: Douglas County, Oregon; about 3 miles east of Dutchman Butte; 2,000 feet north and 1,300 feet west of the southeast corner of sec. 11, T. 31 S., R. 8 W.
RANGE IN CHARACTERISTICS: The soils are dry for 45 to 60 consecutive days following the summer solstice. The mean annual soil temperature is typically 52 to 57 degrees F. but may range to 49 degrees F. (minimum). The solum is 40 to 60 inches thick. Rock fragments of partially weathered sedimentary, metasedimentary, or volcanic rocks range from 50 to 80 percent in the control section. The amount increases with increasing depth. Depth to soft bedrock is 40 to 60 inches.
The A horizon has hue of 10YR or 7.5YR, value of 3 or 4 moist, 5 or 6 dry, and chroma of 2 to 4 moist and dry. It has 35 to 50 percent gravel and 0 to 15 percent cobbles. Soil reaction is slightly acid to neutral.
The Bw horizon has hue of 2.5Y, 10YR, or 7.5YR, value of 3 to 5 moist and 5 to 7 dry, and chroma of 3 to 6 moist and dry. It is extremely gravelly loam, very gravelly loam, or very gravelly clay loam with 22 to 30 percent clay. It has 35 to 55 percent gravel and 10 to 30 percent cobbles. A few pedons have few faint to distinct clay films in the lower horizons. Soil reaction is moderately acid to neutral.
The C horizon, where present, has 60 to 95 percent rock fragments and is loam.
COMPETING SERIES: These are the Atring, Baldhill, Barpeak, Beekman, Chamate (T), Clallam, Farber, Geppert, Hartless, Inskip, Kindig, Mayacama, Neuns, Sheetiron, Straight, Terbies, Vena and Woodin series. The Atring, Beekman, Clallam, Geppert, Inskip, Mayacama, Neuns, Sheetiron, Straight, Vena and Woodin soils are 20 to 40 inches to bedrock. Baldhill soils have 2 to 10 percent clay in the particle-size control section and are dry for 60 to 75 consecutive days during the summer. Barpeak soils are greater than 60 inches deep to bedrock. Chamate and Hartless soils have 10 to 18 percent clay in the particle-size control section and are dry for over 60 consecutive days during the summer. Kindig soils are dry for 80 to 100 consecutive days during the summer and contain slight to moderate amounts of finely divided mica. Terbies soils have a mean annual soil temperature of 47 to 49 degrees F. and have a Bs horizon. Farber soils have 10 to 18 percent clay in the particle-size control section.
GEOGRAPHIC SETTING: Kanid soils are on mountain side slopes, dissected drainageways, and foot slopes. Slopes are 12 to 90 percent. Elevations are 300 to 4,100 feet. Kanid soils formed in colluvium and residuum weathered from sedimentary, metasedimentary, and metavolcanic rocks. The climate is characterized by cool and moist to wet winters and warm to hot dry summers. The mean January temperature is about 40 degrees F; the mean July temperature is about 67 degrees F; the mean annual temperature is 45 to 55 degrees F. The mean annual precipitation is typically 30 to 60 inches but in areas of high winter rainfall may range to 100 inches. The frost-free period is 100 to 235 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Atring and Beekman soils and the Acker, Dumont, McGinnis, Norling, Pollard, Tishar, and Vermisa soils. McGinnis, Dumont, Pollard, and Tishar soils are clayey and have an argillic horizon. Beekman soils are 20 to 40 inches deep to a lithic contact. Vermisa soils are 10 to 20 inches to lithic contact. Norling soils are 20 to 40 inches deep to a paralithic contact. Acker soils are fine-loamy.
DRAINAGE AND PERMEABILITY: Well drained; moderately rapid permeability.
USE AND VEGETATION: Timber production, grazing, wildlife, and watershed. Native vegetation is Douglas fir, grand fir, Pacific madrone, salal, cascade Oregongrape and common snowberry. In high winter rainfall areas of Curry County, Oregon natural vegetation includes Douglas fir, tanoak, Pacific madrone, canyon live oak, and sugar pine.
DISTRIBUTION AND EXTENT: Southwestern part of Oregon in the Coast Range and Siskiyou Mountains; MLRA 5. The series is moderately extensive.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Davis, California
SERIES ESTABLISHED: Jackson County Area, Oregon, 1988.
REMARKS: Diagnostic horizons and features include:
Ochric epipedon
Cambic horizon - the zone from 19 to 48 inches (Bw1 and Bw2 horizons)
Dystric feature - the zone from 10 to 30 inches (lower part of BA and upper part of Bw1 horizon) having an assumed base saturation (NH4OAC) of less than 60 percent
Particle-size control section - the zone from 10 to 40 inches with a weighted average of 54 percent rock fragments
In the interior mountains of Curry County, Oregon the mean annual precipitation ranges up to 100 inches due to elevated winter rainfall; summer periods are hot and dry.
