The Bk horizon has hue of 2.5Y through 7.5YR, value of 5 through 7 dry, 4 through 6 moist, and
<br />chroma of 2 through 6. Texture is typically sandy loam or sandy clay loam but may be fine sandy loam
<br />or very fine sandy loam. Carbonates range from 6 to 14 percent. This horizon does not meet the
<br />requirements of a diagnostic calcic. Discontinuous horizons with greater than 15 percent carbonates
<br />occur in some pedons. 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 weakly
<br />consolidated and does restrict the movement of water and, therefore, roots. Interbedded shales may
<br />be present in some areas and may form the contact.
<br />COMPETING SERIES: These are the Balon, Barx, Buckle, Cambria, Cerrillos, Clovis, Cushman,
<br />Decolney, Fattig, Fernando, Flaco, Forkwood, Gaddes, Gapbutte(T), Hagerman, Harbord, Hiland, Los
<br />Alamos, Maysdorf, Millett, Oelop, Olney, Palacid, Penistaja, Pokeman, Potts, Progresso, Pugsley,
<br />Quagwa, Redpen(T), Scholle, Spangler, Spenlo, Sundance, Tapia, Teckla(T), Threetop, Toluca,
<br />Tuweep, and Yenlo, series in the same family. Balcon, Barx, Buckle, Cambria, Cerrillos, Clovis,
<br />Decolney, Fernando, Forkwood, Harbord, Hiland, Los Alamos, Maysdorf, Millet, Oelop, Olney, Palacid,
<br />Penistaja, Potts, Quagwa, Redpen, Scholle, Spenlo, Sundance, Tapia, Teckla, Toluca, Tuweep, and
<br />Yenlo soils lack bedrock above 40 inches. Cushman soils have less than 35 percent fine sand or
<br />coarser in the Bt horizon. Fattig, Flaco, Gaddes, Gapbutte, Hagerman, Progresso, and Threetop soils
<br />have a lithic contact at 20 to 40 inches. Pokeman soils have alabaster at 20 to 40 inches and hues
<br />redder than 7.5YR throughout. Pugsley and Spangler soils are noncalcareous throughout.
<br />GEOGRAPHIC SETTING: Bowbac soils are on dissected fan remnants, fan piedmonts, hillslopes,
<br />pediments, ridges and buttes. Slopes are 0 to 15 percent. Elevations are 3,500 to 6,500 feet. The
<br />average annual precipitation is 13 inches with over half of the annual precipitation falling in April, May,
<br />and June and less than one inch falling in each month of July, August, September, and October.
<br />Precipitation ranges from 10 to 14 inches. The mean annual temperature ranges from 43 to 51 degrees
<br />F. The frost-free season is about 110 to 130 days.
<br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Cushman, Hiland, and Cambria
<br />soils and the Parmleed soils. Parmleed soils have over 35 percent clay in the Bt horizon.
<br />DRAINAGE AND PERMEABILITY: Well drained; runoff is medium or low; moderate permeability.
