the base of the argillic horizon ranges from 10 to 35 inches. Coarse fragments range
<br />from 0 to 15 percent and are soft sandstone channers or semirounded pebbles. The soil
<br />is dry in the moisture control section more than half the time cumulative that the soil
<br />temperature at a depth of 20 inches is 41 degrees F. and is never moist in some or all
<br />parts for as long as 60 consecutive days when the soil temperature at a depth of 20
<br />inches is 41 degrees F., which occurs about April 21-27, but is dry in all parts of the
<br />moisture control section for at least 60 consecutive days from July 15 to October 25 and
<br />for at least 90 cumulative days during this period. The mean annual soil temperature is
<br />47 to 53 degrees F., and the soil temperature at a depth of 20 inches is 41 degrees F. or
<br />more for 175 to 192 days. EC ranges from 0 to 2 mmhos throughout the profile.
<br />The A horizon has hue of 2.SY through 7.5YR, value of 4 through 6 dry, 3 through 5
<br />moist, and chroma of 2 through 4. Textures are typically sandy loam but may be sandy
<br />clay loam, fine sandy loam, very fine sandy loam, or loam. Reaction is typically neutral
<br />or mildly alkaline but ranges to moderately alkaline in some pedons.
<br />The Bt horizon has hue of 2.5Y through 7.5YR, value of 4 through 6 dry, 3 through 5
<br />moist, and chroma of 2 through 4. In pedons where mollic colors are present in this
<br />horizon, the layer is too thin to meet the requirements for a mollic epipedon. Texture is
<br />sandy clay loam with more than 35 percent fine sand or coarser. Clay ranges from 20 to
<br />35 percent. Reaction is typically mildly alkaline but may range from neutral to
<br />moderately alkaline.
<br />The Bk horizon has hue of 2.5Y through 7.5YR, value of 5 through 7 dry, 4 through 6
<br />• moist, and chroma of 2 through 6. Texture is typically sandy loam or sandy clay loam
<br />but may be fine sandy loam or very fine sandy loam. Carbonates range from 6 to 14
<br />percent. This horizon does not meet the requirements of a diagnostic calcic.
<br />Discontinuous horizons with greater than 15 percent carbonates occur in some pedons.
<br />Reaction is moderately or strongly alkaline with less than 15 percent ESP.
<br />The Cr is a paralithic contact to calcareous, argillaceous sandstone. This material is
<br />weakly consolidated and does restrict the movement of water and, therefore, roots.
<br />Interbedded shales may be present in some areas and may form the contact.

<br />Gapbutte, Hagerman, Progresso, and Threetop soils have a lithic contact at 20 to 40
<br />inches. Pokeman soils have alabaster at 20 to 40 inches and hues redder than 7.5YR
<br />throughout. Pugsley and Spangler soils are noncalcareous throughout.
