McCollough soils have a paralithic contact at depths of 20 to 40 inches. Calcium sulfate accumulation is moderate throughout the control section but is not concentrated in one horizon sufficiently to constitute a gypsic horizon.ĬOMPETING SERIES: These are the McCollough, Nowood and This horizon contains 15 to 25 percent exchangeable sodium. It is strongly to very strongly alkaline (pH 8.8 to 10) and has approximately 2 to 10 percent CaC03 equivalent spread rather uniformly throughout the control section and not concentrated in any particular horizon. The Ccs horizon has hue of 5Y through 10YR. This horizon is strongly to very strongly alkaline (pH 8.8 to 10) and contains 15 to 25 percent exchangeable sodium. The A horizon has hue of 5YR through 10YR, chroma of 1 through 3 and value of 6 or 7 dry and 4 or 5 moist. Content of coarse fragments ranges from 0 to 15 percent but is typically less than 3 percent and consists mostly of shale chips. The control section is typically heavy silty clay loam or light silty clay with clay ranging from 35 to 50 percent, silt from 20 to 50 percent, and sand from 10 to 40 percent with typically less than 15 percent fine sand or coarser.

Cation exchange capacity ranges from approximately 60 to 90 millequivalents per 100 grams of clay. Conductivity of the control section ranges from approximately 2 to 8 millimho and exchangeable sodium ranges from 15 to 25 percent throughout most of the control section. 5 to 1 percent and organic carbon decreases uniformly with depth. The organic carbon content of the A horizon ranges from. RANGE IN CHARACTERISTICS: These soils are calcareous throughout. TYPE LOCATION: Bighorn County, Wyoming approximately 276 feet north and 252 feet east of the junction of the Basin-Gardner road and the old airport access road, in the SW quarter of the SE quarter of sec. (3 to 6 inches thick)Ĭ2cs-8 to 60 inches light brownish gray (2.5Y 6/2 dry) heavy silty clay loam, dark grayish brown (2.5Y 4/2 moist) massive hard, very friable visible secondary calcium sulfate and calcium carbonate occurring as crystals, as small concretions, and in thin seams and streaks calcareous strongly alkaline (pH 9.0). (3 to 6 inches thick)Ĭlca-4 to 8 inches Grayish brown (2.5Y 5/2) heavy silty clay loam, dark grayish brown (2.5Y 4/2) moist moderate and strong fine angular blocky structure very hard, very friable weak to moderate secondary calcium sulfate and calcium carbonate accumulation occurring as crystals and small concretions calcareous strongly alkaline (pH 9.0) gradual smooth boundary. TYPICAL PEDON: Torchlight silty clay loam - grassland (Colors are for dry soil unless otherwise noted.)Ī1-0 to 4 inches light brownish gray (2.5Y 6/2) heavy silty clay loam, dark grayish brown (2.5Y 4/2) moist moderate and strong, very fine granular structure soft, very friable calcareous strongly alkaline (pH 9.0) abrupt smooth boundary. TAXONOMIC CLASS: Fine, smectitic, calcareous, mesic Vertic Torriorthents Typically, Torchlight soils have very friable granular A horizons and gypsiferous, very strongly alkaline fine textured C horizons.
