SHAKESPEARE SERIES

The Shakespeare series consists of very deep, well drained soils that formed in colluvium over residuum formed in metamorphics. The Shakespeare soils are on mountainflanks. Slopes range from 9 to 50 percent. The mean annual precipitation is about 850 millimeters and the mean annual air temperature is about 5 degrees C.

TYPE LOCATION: Douglas County, Nevada; 4 miles northeast of Zepher Cove near Genoa Peak; approximately 152 meters west and 305 meters north of S1/4 corner sec. 30, T.14N., R.19E., Mount Diablo base line and meridian.

RANGE IN CHARACTERISTICS:

Soil moisture: The soils have a typic xeric moisture regime.

Soil Temperature: mean annual soil temperature ranges from 6 to 8 degrees C. The mean summer soil temperature ranges from 12 to 15 degrees C.

Rock fragments: range from 25 to 75 percent in any one horizon and average 35 to 50 percent in the 25 to 75 centimeters section. They range from gravel to boulders but are predominantly gravel and cobbles.

The A1 horizon:
Hue: 10YR or 2.5Y
Value: 4 or 5 dry, 2 or 3 moist
Chroma: 2 or 3
Texture of the fine earth fraction: Sandy loam, loam and silt loam
Reaction: Strongly to slightly acid.

The A2 horizon:
Hue: 10YR or 2.5Y
Value: 6 or 7 dry, 3 or 4 moist
Chroma: 2 or 3 moist or dry
Texture of the fine earth fraction: Sandy loam, loam and silt loam
Reaction: Strongly to slightly acid
Other features: Mottles with hue of 5YR or 10YR, value of 5 through 7, and chroma of 6 to 8 occur in some pedons. These mottles are inherited from the parent material and not due to pedologic processes..

The Bt horizons:
Hue: 2.5Y through 7.5YR
Value: 5 or 6 dry, 4 or 5 moist
Chroma: 2 through 4 dry and moist
Texture of the fine earth fraction: Sandy clay loam, clay loam or clay
Clay content: Averages 25 to 35 percent
Other features: It has few or common, fine or medium mottles with hue of 5YR through 10YR, value of 2 through 6, and chroma of 2 through 8. These mottles are inherited from the parent material and not due to pedologic processes.

The C horizons:
Hue: 5YR through 10YR
Value: 5 or 6 dry, 4 or 5 moist
Chroma: 4 through 6 dry and moist
Texture of the fine earth fraction: Silty clay loam
Clay content: Averages 27 to 40 percent
Rock fragments: 0 to 10 percent gravel and 0 to 5 percent cobbles
Other features: It has few or common, fine or medium mottles with hue of 5YR through 10YR, value of 2 through 6, and chroma of 2 through 8. These mottles are inherited from the parent material and not due to pedologic processes.

COMPETING SERIES: These are the Hardzem soils. Hardzem soils are derived from limestone and shale and have paralithic contact between 50 and 100 cm.

GEOGRAPHIC SETTING: Shakespeare soils are on strongly sloping to steep mountain flanks at elevations of 2335 to 2695 meters. Slope gradients range from 9 to 50 percent. The soils formed in material from mixed, undifferentiated metamorphic rocks. The climate is cool, subhumid. Mean annual precipitation is 760 to 1020 cm most of which comes as winter snow. The mean annual temperature is 3 to 6 degrees C.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Dagget, Temo, and Witefels soils. These soils lack argillic horizons and are derived from granitic rock sources. All of these soils are on similar landforms.

DRAINAGE AND PERMEABILITY: Well drained; high runoff; slow permeability.

USE AND VEGETATION: Used for woodland and wildlife. Native vegetation is mainly white fir, red fir, lodgepole pine, and manzanita.

DISTRIBUTION AND EXTENT: Lake Tahoe Basin, Douglas, Carson City Rural Area, and Washoe Counties, Nevada. The series is of minor extent.
