NOTELLUMCREEK SERIES

The Notellumcreek series consists of shallow, well drained soils that formed in residuum and colluvium derived from welded tuff. The Notellumcreek soils are on mountains. Slopes are 15 to 50 percent. The mean annual precipitation is about 575 mm and the mean annual temperature is about 4.5 degrees C.

TAXONOMIC CLASS: Ashy-skeletal, glassy, frigid Lithic Argixerolls

TYPICAL PEDON: Notellumcreek very stony ashy loam--rangeland. (Colors are for dry soil unless otherwise noted.) The soil surface is partially covered with approximately 20 percent gravel, 20 percent cobbles, 10 percent stones, and 5 percent boulders. The soil is generally associated with areas of Rock outcrop.

A1--0 to 5 cm; grayish brown (10YR 5/2) very stony ashy loam, very dark grayish brown (10YR 3/2) moist; moderate coarse subangular blocky structure parting to moderate medium granular; soft, very friable, slightly sticky and nonplastic; common very fine and fine roots; common very fine and fine, and few medium interstitial and tubular pores; 10 percent gravel, 10 percent cobbles, and 15 percent stones; slightly acid (pH 6.3); clear smooth boundary.

A2--5 to 18 cm; grayish brown (10YR 5/2) very stony ashy loam, very dark grayish brown (10YR 3/2) moist; strong medium subangular blocky structure parting to moderate medium granular; soft, very friable, slightly sticky and slightly plastic; common very fine and fine, and few medium roots; common very fine and fine, and few medium interstitial and tubular pores; 15 percent gravel, 10 percent cobbles, and 10 percent stones; moderately acid (pH 5.9); clear smooth boundary. (Combined thickness of the A horizons is 5 to 30 cm)

Bt1--18 to 28 cm; yellowish brown (10YR 5/4) very stony ashy clay loam, dark brown (10YR 3/3) moist; strong coarse subangular blocky structure parting to moderate medium subangular blocky; slightly hard, friable, slightly sticky and slightly plastic; few very fine and medium, and common fine roots; common very fine and fine interstitial and tubular pores; common faint clay films on faces of peds; 15 percent gravel, 20 percent cobbles, and 15 percent stones; slightly acid (pH 6.2); clear smooth boundary.

Bt2--28 to 38 cm; yellowish brown (10YR 5/4) very stony ashy clay loam, dark yellowish brown (10YR 3/4) moist; strong coarse subangular blocky structure parting to moderate medium subangular blocky; slightly hard, friable, moderately sticky and moderately plastic; few very fine and fine roots; common very fine and fine, and few medium interstitial and tubular pores; many faint clay films on faces of peds; 15 percent gravel, 20 percent cobbles, and 15 percent stones; neutral (pH 6.6); abrupt smooth boundary. (Combined thickness of Bt horizons 31 to 60 cm)

R--38 cm; indurated welded tuff bedrock.

COMPETING SERIES: These are the Badrock, Domehill, Farepeak, Fingerridge, Hardnut, Hardteph, Mattier, Schoolmarm, Skidbrackle, Starflyer and Wellthomas series.

Badrock soils have 18 to 27 percent clay in the particle-size control section and a mean annual soil temperature of 7 to 8 degrees C. Domehill, Farepeak, Fingerridge, Hardteph, Mattier, and Wellthomas soils have lithic contacts at depths of less than 36 cm. Hardnut soils contain 60 to 80 percent rock fragments in the particle-size control section which are mainly gravel. Schoolmarm soils have an aridic soil moisture regime bordering on xeric and have a mean annual soil temperature of 7 to 8 degrees C. Skidbrackle soils contain 50 to 80 percent volcanic glass content in the coarse silt through fine sand fractions. Starflyer soils have a mean annual soil temperature of 7 to 8 degrees C and a xeric soil moisture regime bordering on aridic.

GEOGRAPHIC SETTING: Notellumcreek soils are on mountains. These soils formed in colluvium and residuum derived from welded tuff. Slopes are 15 to 50 percent. Elevations range from 2,500 to 2,950 meters. The climate is moist-subhumid with cold wet winters and warm dry summers. The mean annual precipitation is 450 to 700 mm; mean annual temperature is 4 to 6 degrees C; and frost-free period is 40 to 70 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Crethers, the competing Schoolmarm, and Tusel series. Crethers soils are very deep, and have 35 to 40 percent clay in the particle-size control section. Tusel soils are deep or very deep.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained; moderately low saturated hydraulic conductivity.

USE AND VEGETATION: Notellumcreek soils are used for livestock grazing and wildlife habitat. The potential native vegetation is mainly, bluebunch wheatgrass, mountain big sagebrush, and curlleaf mountainmahogany.
This site is correlated to Ecological Site R28BY032NV, Stony Mahogany Savanna.

DISTRIBUTION AND EXTENT: East central Nevada. These soils are not extensive. The series concept and main acreage is in MLRA 28B, while other acreage occurs in MLRA 28A.
