• TYPE LOCATION: Campbell County, Wyoming; 1250 feet north and 1350 feet west of the southeast comer of
<br />sec. 23, T. 42 N., R. 72 W. 43 degrees 35 minutes 45 seconds north latitude and 105 degrees 28 minutes 5
<br />seconds west longitude.
<br />RANGE IN CHARACTERISTICS: Depth to soft sandstone ranges from 20 to 40 inches. Depth to continuous
<br />carbonate accumulation ranges from 10 to 35 inches, and depth to the base of the argillic horizon ranges from 10
<br />to 35 inches. Coarse fragments range from 0 to 15 percent and are soft sandstone charmers or semirounded
<br />pebbles. The soil is dry in the moisture control section more than half the fime cumulative that the soil temperature
<br />at a depth of 20 inches is 41 degrees F. and is never moist in some or all parts for as long as 60 consecutive days
<br />when the soil temperature at a depth of 20 inches is 41 degrees F., which occurs about April 21-27, but is dry in all
<br />parts of the moisture control section for at least 60 consecutive days from July 15 to October 25 and for at least 90
<br />cumulative days during this period. The mean annual soil temperature is 47 to 53 degrees F., and the soil
<br />temperature at a depth of 20 inches is 41 degrees F. or more for 175 to 192 days. EC ranges from 0 to 2 mmhos
<br />throughout the profile.
<br />The A horizon has hue of 2.5Y through 7.5YR, value of 4 through 6 dry, 3 through 5 moist, and chroma of 2 through
<br />4. Textures are typically sandy loam but maybe sandy day loam, fine sandy loam, very fine sandy loam, or loam.
<br />Reaction is typically neutral 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 moist, and chroma of 2 through
<br />4. In pedons where mollic colors are present in this horizon, the layer is too thin to meet the requirements for a
<br />mollic epipedon. Texture is sandy Gay loam with more than 35 percent fine sand or coarser. Clay ranges from 20
<br />to 35 percent. Reaction is typically mildy alkaline but may range from neutral to moderately alkaline.
<br />The Bk horizon has hue of 2.5Y through 7.5YR, value of 5 through 7 dry, 4 through 6 moist, and chroma of 2
<br />through 6. Texture is typically sandy loam or sandy Gay loam but may be fine sandy loam or very fine sandy loam.
<br />Carbonates range from 6 to 14 percent. This horizon does not meet the requirements of a diagnostic celcic.
<br />Discontinuous horizons with greater than 15 percent carbonates occur in some pedons. Reaction is moderately
<br />or strongly alkaline w'rfh less than 15 percent ESP.
<br />The Cr is a paralithic contact to calcareous, argillaceous sandstone. This material is weakly consolidated and does
<br />restrict the movement of water and, therefore, roots. Interbedded shales may be present in some areas and may
<br />form the contact.
