TYPE LOCATION: Teller County, Colorado; on the Manitou Forest Experimental Station, approximately 1/4 mile southeast of the headquarters; in the NE 1/4 of Sec. 14, T. 11 S., R. 69 W.
RANGE IN CHARACTERISTICS: The thin A1 horizon is absent in some pedons. These soils are usually calcareous and have visible secondary calcium carbonate in some subhorizon above the bedrock or, if lacking these characteristics, at least part of the B2t is mildly alkaline and there is at least a subhorizon 4 inches thick above the bedrock with pH of 7.6 or more. Base saturation ranges from 60 to 100 percent. Depth to th lithic contact ranges from 20 to 40 inches. Depth to the base of the argillic horizon ranges from 17 to 40 inches. Rock fragments range from 0 to 35 percent in a major part of the solum and many C horizon and these are mainly 1/8 to 1/2 inch in diameter.
A major part of the solum and C horizon above the bedrock has hue of 5YR or redder. Within the sand fraction the content of medium and coarse angular sand having a large proportion of flat bearing surfaces between sand grains ranges from 15 to about 90 percent and horizons of low organic matter content have a differential between dry and moist consistence that is 1 to 3 times greater than soils of similar texture having finer and more rounded sand grains. These soils are dry in some part of the moisture control section at some time in most years. The A2 horizon has hue of 10YR through 5YR, value of 5 through 8 dry, 4 through 7 moist, and chroma of 1 through 4. It ranges from slightly acid to mildly alkaline (1:5 dilution unbuffered organic dye). The B2t horizon has hue of 5YR through 10YR, value of 5 through 7 dry, 3 through 6 moist, and chroma of 1 through 6. Subhorizons yellower than 5YR occur in some pedons. This horizon is typically gravelly coarse sandy clay loam but clay ranges from 18 to 35 percent, silt from 5 to 15 percent, and sand from 40 to 75 percent with more than 35 percent being fine or coarser sand and with a high proportion of medium and coarse sand. It is slightly acid to mildly alkaline. The C horizon, if present, normally ranges from 5YR through 10YR. Subhorizons yellower than 5YR occur in some pedons. Calcium carbonate equivalent of the fine earth ranges from 1 to 10 percent. This horizon is typically gravelly coarse sandy loam but clay ranges from 5 to 18 percent, silt from 5 to 35 percent, and sand from 45 to 87 percent with more than 35 percent being fine or coarser sand and with a large proportion of medium and coarse angular sand. It is mildly or moderately alkaline (1:5 dilution unbuffered organic dye).
COMPETING SERIES: These are the Ansel, Grimes, Hiero, Indart, Lick, Linber, Peeler, Polvadera, Sapphire, Schofield, Shule, Swapps, Swifton, Tahoma, Tongue River, Trapper, Uinta, Whitefish, and Woodrock series. Ansel, Hiero, Lick, Peeler, Trapper, Swifton, Uinta, and Whiterfish soils lack bedrock at depths of 40 inches or less. Grimes, Saphhire, and Shule soils are noncalcareous throughout, lack horizons of secondary carbonate accumulation, and have less than 35 percent fine or coarser sand in the solum and C horizon. Indart and Tongue River soils have a paralithic contact at depths of 40 inches or less. Limber soils have hue of 7.5YR or yellower in a majority of subhorizons, have less than 35 percent fine or coarser sand in the argillic horizon, and lack A&B horizons. Polvadera soils have fine textured lower solums and C horizons. Swapps soils have solums less thick than 17 inches to the base of the argillic horizon, lack any A2 horizon or any A&B horizon, and are calcareous throughout most of the solum. Tahoma soils have solums more than 50 inches thick, and lack any A2 or A&B horizons. Woodrock soils have less than 60 base saturation in at least part of the solum and have hue of 7.5YR or yellower in a majority of subhorizons above the bedrock.
GEOGRAPHIC SETTING: The Edloe soils are on gently to steeply sloping hills, ridges, and mountain sides. Slopes typically range from about 2 to 40 percent or more. The soil formed in moderately thin, moderately coarse textured materials weathered residually or locally transported from granite bedrock. At the type of location the mean annual precipitation is about 24 inches with peak periods of precipitation in the spring and early summer months. Mean annual temperature is 3 degrees F. and mean summer temperature is 57 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Peeler and Schofield soils.
DRAINAGE AND PERMEABILITY: Well drained; medium to rapid runoff; moderate to rapid permeability.
USE AND VEGETATION: Used as grazing land, for recreation, and for timber production. Native vegetation is ponderosa pine, lodgepole pine, grasses, and shrubs.
DISTRIBUTION AND EXTENT: Mountainous areas of central Colorado. The series is of small extent.
