BINDLE SERIES
The Bindle series consists of moderately deep, well drained soils that formed in mixed ash, loess and colluvium over fractured andesite or basalt. Bindle soils are on uplands. Slopes are 1 to 70 percent. The mean annual precipitation is about 32 inches and the mean annual temperature is about 43 degrees F.
TAXONOMIC CLASS: Loamy-skeletal, isotic, frigid Vitrandic Humixerepts
TYPICAL PEDON: Bindle gravelly ashy loam, forested. (Colors are for moist soil unless otherwise noted.)
Oi--0 to 1 inch; fir twigs and needles.
A--1 to 7 inches; dark brown (7.5YR 3/2) gravelly ashy loam, brown (7.5YR 5/3) dry; moderate medium granular structure; slightly hard, friable, slightly sticky and slightly plastic; many very fine roots; few medium roots; many very fine irregular pores; 20 percent gravel, 5 percent cobbles; neutral (pH 6.6); clear smooth boundary. (4 to 8 inches thick)
AB--7 to 14 inches; dark brown (7.5YR 3/3) gravelly ashy loam, brown (7.5YR 5/4) dry; moderate medium subangular blocky structure; slightly hard, friable, slightly sticky and slightly plastic; many very fine and few medium roots; many very fine tubular pores; 20 percent gravel, 5 percent cobbles; slightly acid (pH 6.5); gradual wavy boundary. (3 to 7 inches thick)
Bw--14 to 23 inches; brown (7.5YR 4/3) very gravelly ashy clay loam, brown (7.5YR 5/3) dry; weak fine subangular blocky structure; slightly hard, friable, sticky and plastic; many very fine and medium roots; many very fine tubular pores; 45 percent gravel, 10 percent cobbles; slightly acid (pH 6.5); gradual wavy boundary. (7 to 25 inches thick)
2R--23 inches; highly fractured bedrock with horizontal spacing between the cracks 4 to 6 inches apart; few fines are in some of the cracks in the upper few inches.
TYPE LOCATION: Hood River County, Oregon; south of road in the NE1/4 SW1/4 sec. 23, T.1N., R.10E.
RANGE IN CHARACTERISTICS: The mean annual soil temperature ranges from 44 to 47 degrees F. The soils are usually moist but are dry in all subhorizons between depths of 4 and 12 inches for 60 to 80 consecutive days within the 4 months following the summer solstice. Depth to highly fractured bedrock is 20 to 40 inches. The solum is estimated to have a volcanic glass content of 5 to 20 percent and acid oxalate extractable aluminum plus one-half iron of 0.4 to 1.0 percent. The umbric epipedon is 7 to 15 inches thick.
The A horizon has hue of 5YR or 7.5YR, value of 2 or 3 moist, 4 or 5 dry, and chroma of 2 or 3 moist and dry. It has 20 to 35 percent fine gravel and/or concretions 1/8 to 1/2 inch in diameter and 0 to 10 percent stones.
The AB and Bw horizon has hue of 2.5YR, 5YR or 7.5YR, value of 3 or 4 moist, 4 or 5 dry, and chroma of 3 or 4 moist and dry. It is gravelly or cobbly ashy clay loam and has 20 to 40 percent gravel, 5 to 20 percent cobbles and 5 to 10 percent stones and averages 35 to 60 percent rock fragments.
The 2R layer ranges from highly fractured bedrock with no displacement and little fines in the fractures to bedrock with cracks more than 12 inches apart.
COMPETING SERIES: There are no competing series.
GEOGRAPHIC SETTING: The Bindle soils have nearly level to moderately steep slopes with gradients ranging from 1 to 70 percent and are at elevations of 2,500 to 3,500 feet. The soils formed in colluvium composed of volcanic ash mixed with loess and stony colluvium weathered from andesite or basalt overlying fractured andesite or basalt. The climate is characterized by cold wet winters and hot dry summers. The mean July temperature is 60 degrees F.; the mean January temperature is 30 degrees F. The mean annual temperature is 42 to 45 degrees F. The mean annual precipitation is 25 to 40 inches. The frost-free period is 50 to 100 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Bins soils. Bins soils have less than 35 percent rock fragments.
DRAINAGE AND PERMEABILITY: Well drained; moderate permeability.
USE AND VEGETATION: Principal use is for timber production. Other uses are for grazing, wildlife, and recreation. Overstory vegetation is mainly Douglas fir, grand fir, chinkapin, maple and willow. Brush plants are trailing blackberry, false-Solomon seal and hazel. Grasses are bluegrass and mountain brome with elk sedge.
DISTRIBUTION AND EXTENT: Western Wasco and Hood River Counties in north-central Oregon; MLRA 6. These soils are inextensive.
