• 10 percent Aquic Cryoborolls and 5 percent Tonks soils. The soils in the mapping unit do not occur in an identifiable geographic sequence. Typically the fine-loamy Pachic Cryoborolls have a very dark grayish brown loam surface layer 24 inches thick and a light olive brown and dark grayish brown loam and sandy loam substratum 36 inches thick. Depth to a seasonal high water table is estimated to be about 43 inches. Permeability is moderate, and the available water capacity is high. Effective rooting depth is 60 inches or greater. The Adel Variant sails typically have a very dark gray clay loam surface layer 20 inches thick, a dark grayish brown loam subsoil 11 inches thick, and a dark gray, dark grayish brawn and gray loam and sandy loam substratum 29 inches thick. Depth to a seasonal high water table is estimated to be about 44 inches. Permeability is moderately slow, and the available water capacity is high. Effective rooting depth is 44 inches or greater. Surface runoff is slow. • 4--Bozeman Silt Loam, 3 to 12 percent slopes. This mapping unit consists of deep, well drained, gently to strongly sloping soils forming on alluvial fans and high terraces. These soils are forming in moderately fine and fine textured colluvium derived from mixed sources. They occur along Fish Creek. The mapping unit is composed of approximately 90 percent Bozeman Series. Included in the mapping unit are approximately 5 percent Buckskin soils and 5 percent Pachic Cryoborolls. Typically the Bozeman soils have a very dark grayish brown silt loam surface layer 8 inches thick, a dark brown silt loam, silty clay loam and silty clay subsoil 25 inches thick, and a dark yellowish brown and yellowish brown silty clay and silty clay loam substratum 27 inches thick. Permeability is slow and the available water capacity is high. Effective rooting depth is 60 or more inches. Surface runoff is medium to rapid. • Ex. 16-10
