TYPICAL PEDON: Kebler sandy loam, forested. (Colors are for dry soil unless otherwise noted.)
01--2 to 1 inch; undecomposed organic material mainly needles, twigs, and bark.
02--1 inch to 0; partially decomposed organic material.
A21--0 to 4 inches; light brownish gray (10YR 6/2) sandy loam, dark grayish brown (10YR 4/2) moist; weak fine subangular blocky structure that parts to moderate very fine granules; vesicular; soft, very friable, very strongly acid; clear smooth boundary. (2 to 6 inches thick)
A22--4 to 9 inches; very pale brown (10YR 7/3) light sandy loam, brown (10YR 5/3) moist; very weak platy structure that parts to weak fine subangular blocks and very fine granules; vesicular; soft, very friable; clear wavy boundary. (2 to 8 inches thick)
A&B--9 to 13 inches; brown (10YR 5/3) fine sandy loam, brown (10YR 4/3) moist; weak medium subangular blocky structure; slightly hard, very friable; 80 percent of material like that of the overlying horizon in which is imbedded nodules and seams of more clayey material like that of the underlying B2t horizon; 5 percent rock fragments; very strongly acid; clear wavy boundary. (4 to 10 inches thick)
B2t--13 to 24 inches; yellowish brown (10YR 5/4) very stony sandy loam, dark yellowish brown (10YR 4/4) moist; weak medium subangular blocky structure; slightly hard, very friable; common thin discontinuous clay films on peds; clay coating on sand grains and clay bridges between sand grains; 60 percent rock fragments very strongly acid; gradual smooth boundary. (7 to 18 inches thick)
R--24 to 30 inches; hard sandstone.
TYPE LOCATION: Gunnison County, Colorado; north of the trail near the center of Sec. 33, T. 13 S., R. 83 W.
RANGE IN CHARACTERISTICS: Thickness of the solum ranges from 16 to 40 inches, and depth to bedrock ranges from 20 to 40 inches. These soils have intervening C horizons in some pedons where bedrock is deep, and have thin dark colored A1 horizons in some pedons. Rock fragments range from 35 to 85 percent and are mostly sandstone fragments more than 10 inches in diameter. Reaction ranges from pH 4.5 to 5.5.
The A2 horizon has hue of 2.5Y through 7.5YR, value of 6 or 7 dry, 4 or 5 moist, and chroma of 1.5 through 3. Dry consistence is soft or slightly hard. This horizon tongues into the B2t horizon.
The B2t horizon has hue of 2.5Y through 7.5YR, value of 5 or 6 dry, 4 or 5 moist, and chroma of 3 through 6. Dry consistence is hard or slightly hard. The fine earth fraction is typically sandy loam and has 10 to 18 percent clay, 5 to 35 percent silt, and 50 to 80 percent sand.
COMPETING SERIES: These are the Agnestion, Angostura, Cloud Peak, Cundiyo, Duchesne, Frisco, Gambler, Granile, Hyattville, Jorge, Lake Creek, Lakehelen, Larand, Leadville, Lulude, MacFarlane, Tenrag, Tolvar Worock, and Zabel series. All except Agneston, Cloud Peak, Hyattville, Lake Creek, Lakehelen and Lulude soils are deeper than 40 inches to bedrock. Agneston, Cloud Peak, Hyattville, Lake Creek and Lulude soils have more than 18 percent clay in their control section. Lakehelen soils have hue of 5YR or redder.
GEOGRAPHIC SETTING: The Kebler soils are on mountain side slopes and ridges. Slopes range from 2 to 50 percent. The soils formed in moderately coarse textured strongly acid parent materials weathered from underlying sandstone. At the type location the average annual precipitation is 20 inches with generally uniform distribution occurring throughout the year. The mean annual temperature is about 32 to 36 degrees F., and the frost-free season is about 40 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Eyre, Sawcreed, and Tongue River soils. Eyre soils have bedrock at depths of 10 to 20 inches and have mollic epipedons. Sawcreek soils have mollic epipedons. Tongue River soils have less than 35 percent rock fragments in the control section.
DRAINAGE AND PERMEABILITY: Well drained; medium to slow runoff; rapid permeability.
USE AND VEGETATION: These soils are used for forestry, for rangeland, and for recreational purposes. Native vegetation is mainly lodgepole pine with an understory of vaccinium, lupine, juniper, peavine, and scattered grasses.
DISTRIBUTION AND EXTENT: High mountain areas of central Colorado. The series is of moderate extent.
