Type Location: These sails are located neaz the center of Section 26,
T.155., R.85W, in Gunnison County, Colorado.
Range in Chazacteristics: Thickness of the mollic epipedon ranges from
7 to 15 inches, depth to calcazeous material ranges from 15 to 40 inches,
and thickness of the solum ranges from 20 to 50 inches. Organic carbon
in the mollic epipedon ranges from 0.8 to 2 percent and decreases
uniformly with increasing depth. The soil is 90 to 100 percent base
saturated. Cation exchange capacity ranges from approximately 60 to
90 milliequivalents per 100 grams of clay. Rock fragments range from
15 to 35 percent in a majority of the control section and aze mainly of
gravel size.
The Al horizon has hue of 2.5Y through 7.SYR, value of 4 or 5 dry,
2 or 3 moist and chroma of 1 or 2. It ranges from soft to slightly hazd.
• The B2t horizon has hue of 2.SY through 7.SYR, value of 5 or 6 dry, 3
through 5 moist, and chroma of 2 through 4. It usually has prismatic to
subangulaz blocky structure but has angulaz blocky structure in some
pedons. The B2t horizon is gravelly heavy clay loam or light clay and has
35 to 50 percent clay. It is neutral or mildly alkaline. The Cca horizon
has hue of 2.SY through 7.SYR. It ranges from pH 8.0 to 8.6, and the
calcium cazbonate equivalent ranges from approximately 4 to 12
percent.
Competing Series: These are the Arling, Brinkert, Brolliaz, Buckskin,
Florissant, Getta, Gothic, Gurney, Heath, Judy, Little Horn, Mayoworth,
Owen Creek, Segal, Sessions, Sneffels, Trout Creek, Waters and Youman
series. Arling soils have a significant component of volcanic ash and
other pyroclastics. Brinkert, Getta, Gothic and Youman soils lack
cazbonate above a depth of 40 inches and do not have ca horizons.
Brolliaz, Judy, Little Horn, Sneffels and Waters soils have a lithic
