Mean annual soil temperature ranges from 39 to 46 degrees F., and mean summer soil temperature ranges from 47 to 55 degrees F. Depth to secondary calcium carbonate accumulation is 40 inches or more. Reaction is slightly acid through mildly alkaline. It is typically loam, sandy clay loam, or clay loam with or without gravelly modifiers and has 18 to 35 percent clay. Reaction is slightly acid through mildly alkaline. It is typically sandy loam, fine sandy loam, loam, sandy clay loam, or clay loam and less commonly a sandy loam with 14 to 35 percent clay.
Reaction is neutral through moderately alkaline.
Amsden, Gebson, Gelkie, Leavitt, Michelson, Monida, Morset, Oro Fino , Philipsburg, Tingey, and Wellsville soils have consistent horizons of visible secondary calcium carbonate accumulation above a depth of 40 inches. Hourglass soils formed in material weathered from limestone and sandstone and have moisture control sections that are dry less than 45 days when the temperature at 20 inches is greater than 41 degrees F. Buffork, Cific, Inchau, Lymanson, Rainbolt, and Tripit soils have a paralithic contact above a depth of 40 inches. Kittredge soils contain a significant proportion of flat mica platelets numerous enough and large enough to affect the soil's physical characteristics. Lyonman soils are medium acid below a depth of about 2 feet, have some mottling in the C horizon, and occur in areas of dominant winter precipitation. Coldspring soils have 5YR or 2.5YR hue in the Bt and C horizons.
