TYPE LOCATION: Douglas County, Oregon, 1,300 feet north and 400 feet west of the S.E. corner of section 13, T. 26 S., R. 4 W. (Latitude 43 degrees, 18 minutes, 14 seconds N, Longitude 123 degrees, 6 minutes, 34 seconds W.
RANGE IN CHARACTERISTICS: The soils are usually moist, but are dry for 50 to 80 consecutive days in all parts between depths of 8 to 24 inches during the 4 month period following summer solstice. The mean annual soil temperature is 52 to 57 degrees F. Ash deposits overlie a variety of rocks and mixed kinds of alluvium to a depth of greater than 60 inches. Thickness of the mollic epipedon is 20 to 40 inches. The moist bulk density is 0.70 to 0.90 g/cubic centimeter in the solum and range to 1.0 in the substratum. Phosphate retention is 25 to 40 percent throughout the solum. Glass content is 20 to 40 percent. Acid oxalate aluminum plus one-half iron is 0.4 to 1.5 percent. The 15-bar water retention is 5 to 15 percent on dry samples and 15 to 30 percent on undried samples. Field estimated clay content is 5 to 10 percent.
The A horizon has value of 2 or 3 moist, 3 or 4 dry, and chroma of 1 or 2 moist and dry. It has 0 to 25 percent fine and medium pumiceous gravel. It is moderately acid to slightly acid.
The AC horizon has value of 2 or 3 moist, 3 or 4 dry, and chroma of 1 or 2 moist and dry. It is gravelly sandy loam or gravelly loamy sand and has 15 to 25 percent fine and medium pumiceous gravel.
The C horizon has hue of 10YR or 7.5YR, value of 2 to 4 moist, 3 to 5 dry, and chroma of 2 to 4 moist and dry. It is gravelly loamy sand or gravelly sand and has 15 to 35 percent pumiceous gravel. It is slightly acid to neutral.
COMPETING SERIES: This is the Chemawa, Parkdale, Shasta, Trouter and Walvan series. Parkdale soils have an umbric epipedon, a phosphate retention of 85 percent or more, field textures of silt loam or loam, and acid oxalate aluminum plus one-half iron of 2 to 3 percent. Chemawa soils have an umbric epipedon, a phosphate retention of 50 to 75 percent, and apparent field textures of loam or silt loam. Trouter soils are 20 to 40 inches to a lithic contact. Shasta soils are 20 to 40 inches deep to sand and gravel. Walvan soils are silt loam throughout, have a phosphate retention of 50 to 75 percent and lack gravel size fragments.
GEOGRAPHIC SETTING: Glide soils are on flood plains. The soils formed in alluvium weathered primarily from Mt. Mazama ash. Slopes are 0 to 3 percent. Elevations are 400 to 800 feet. The climate is characterized by warm, wet winters and hot, dry summers. The mean annual temperature is 50 to 55 degrees F. The mean annual precipitation is 35 to 55 inches. The frost-free period is 160 to 235 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bashaw, Camas, Chapman, Chehalis, Coburg, Conser, Evans, Newberg, Packard, Redbell, Roseburg, Sibold, and Waldo soils. Bashaw soils are very-fine and on terraces. Camas soils are sandy-skeletal. Chapman soils are fine-loamy. Chehalis soils are fine-silty. Evans and Newberg soils are coarse-loamy. Waldo soils are fine. All of these soils are on lower surfaces that flood on an occasional to frequent basis. Packard soils are loamy-skeletal and on flood plains and terraces. Coburg soils are fine and on flood plains and terraces. Conser soils are poorly drained and on terraces. Redbell soils are somewhat poorly drained and on terraces. Roseburg and Sibold soils are fine-loamy and on flood plains.
DRAINAGE AND PERMEABILITY: Well drained; moderately rapid permeability; rare flooding.
USE AND VEGETATION: Glide soils are used for hay and pasture and cropland.
DISTRIBUTION AND EXTENT: Southwestern Oregon, MLRA 5. Series is of small extent.
