• 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. <br />COMPETING SERIES: These are the Balon, Banc, Buckle, Cambria, Cerrillos, Clovis, Cushman, Decolney, Fatfig, <br />Fernando, Flaco, Forkwood, Gaddes, Gapbutte(T), Hagerman, Harbord, Hiland, Los Alamos, Maysdorf, M11ett, <br />Oelop, Olney, Paladd, Penistaja, Pokeman, Potts, Progresso, Pugsley, Quagwa, Redpen(T), Scholle, Spangler, <br />• <br />(Revised March 2006) Attachment 2.04.9-3-13 <br />
