MAUDE SERIES
Typically, Maude soils have very fine sandy loam profiles that are slightly acid. Average annual soil temperature is about 42 degrees F. Slopes are 4 to 90 percent.
TAXONOMIC CLASS: Medial, glassy Humic Vitricryands
TYPICAL PEDON: Maude loam, mountain meadow. (Colors are for dry soil unless otherwise indicated.)
A1--0 to 2 inches; dark grayish brown (10YR 4/2) loam, very dark grayish brown (10YR 3/2) moist; massive; soft, friable, slightly sticky, nonplastic; common fine and medium roots; many fine and medium tubular pores; slightly acid (pH 6.5); gradual wavy boundary. (2 to 6 inches thick)
2 to 7 inches; dark brown (10YR 4/3) very fine sandy loam, dark
brown (10YR 3/3) moist; massive; soft, friable, slightly sticky, nonplastic; common fine and medium roots; many fine and medium tubular pores; some pumice; moderately acid (pH 6.2); gradual wavy boundary. (3 to 7 inches thick)
B--7 to 19 inches; brown (10YR 4/3) very fine sandy loam, dark brown (10YR 3/3) moist; massive; soft friable, slightly sticky, nonplastic; common fine and medium roots, many fine and medium tubular pores, some pumice; moderately acid (pH 6.0); gradual wavy boundary. (8 to 14 inches thick)
C--19 to 39 inches; brown (10YR 5/3) very fine sandy loam, dark
brown (10YR 3/3) moist; massive; soft, friable, slightly sticky, slightly plastic; few fine and medium roots, many fine and medium tubular pores; some pumice; slightly acid (pH 6.2). (5 to 20 inches thick)
TYPE LOCATION: Chelan County, Washington; Entiat Ranger District, 11 miles up Entiat trial from Cottonwood Guard Station; first big meadow above Glenn Camp in the Entiat Meadows; SW1/4 NE1/4 sec. 28, T.31N., R.17E., W.M.
RANGE IN CHARACTERISTICS: Mean annual soil temperature at a depth of 20 inches ranges from 40 degrees to 43 degrees F., with mean summer temperature about 50 degrees F. These are usually moist. The 10- to 40- inch control section is loam or very fine-sandy loam and contains 5 to 30 percent coarse fragments. The soils range from slightly acid to strongly acid. The umbric epipedon is thicker than 20 inches. Content of pyroclastic material (ash) exceeds 60 percent. These soils are massive in all parts. Depth to glacial till ranges from 30 to 45 inches.
The A horizon has dry value of 3 or 4, and dry chroma of 2 or 3.
The B horizon has dry values of 4 or 5, and dry chroma of 2 or 3. Textures are very fine sandy loam, gravelly loam or gravelly very fine sandy loam.
The C horizon has dry value of 4 through 6, and dry chroma of 2 or 3. Textures are very fine sandy loam, gravelly very fine sandy loam or very gravelly loam. Skellock and Steiger soils lack umbric epipedons.
GEOGRAPHIC SETTING: These soils are on broad valley bottom and toe slope positions at elevations of 3,000 to 5,900 feet. They formed in alluvial and colluvial materials underlain by glacial till. The average annual temperature at 20 inches depth is approximately 42 degrees F. The average annual precipitation ranges between 55 to 70 inches, mostly in the form of snow.
GEOGRAPHICALLY ASSOCIATED SOILS:
DRAINAGE AND PERMEABILITY: Well-drained; medium runoff; moderate permeability.
USE AND VEGETATION: Used for wildlife habitat, watershed, recreation, and grazing. Trees are widely scattered Pacific silver fir and subalpine fir, and the understory is dominated by green fescue, sedges, and annuals.
DISTRIBUTION AND EXTENT: North-central Washington, east slope of the Cascades. This series is inextensive.
