Descripr.ion 53 KIM LOA?1, 1 TO 3 PERCENT SLOPES This nearly level soil is on uplands and fans. In r_luded with this soil in mapping are a few small areas of soils that are mot? or less sloping, a few small areas of soils that hate a surface layer of clay loam, and a few small areas of soils that have gravel on the surface. Also included are a small areas of Fort Collins and Ston?ham sails. A water table is within the root Zone for parr. of the growing season in a few areas. The Rim series consists of deep, well drained soils that formed in mixed alluvium. Typicallc, the surface layer is a loam about 12 inches thick. The underlying material is loam about 48 inches thick. Permeability is moderat?, and the available water holding capacity is high. Reaction is mildly alkaline above a depth of 12 inches and moderately alkaline below r.hat depth. Runoff is slow. The hazard of wirer erosion is slight, and the hazard of wind erosion is moderate. This unit is a Loamy Plains rang? site, Capability unit is IIe-1 Irrigated, IVe-3 Drvland 56 KIM-THEDALUND LOAMS, 3 TO 15 PERCEPT SLOPES This complex consists of gently sloping to moderately steep soils on uplands, fans, and vallepsides. Zt is about. 45 percent Rim loam and about 35 percent Thedalund loam. The Ki.m loam is less sloping and th=_ Th=.da h.md loam is steeper. Included with these soils in mapping are small areas of Renohill and Midway soils, small rock outcrops and gravel knobs, and some small wet seep spots. The Kim series consists of deep, well drained soils that formed in mixed alluvium. In a typical soil profile the surface layer is a loam about 5 inches thick. The underlying material is a loam about 55 inches thick. The Thedalund series consists of moderately deep, well drained soils that formed in material weathered from sandstn~re and shale. In a typical soil. profile the surface layer i.s a loam about 4 inches thick. The subsurface layer is a loam about 4 inches thick.
