Fluctuating water tables occur in these soils in some season of some <br /> years. <br /> ' The A horizon has hue of IOYR through SY,value of 5 through 7 dry, 3 through 5 moist, and <br /> chroma of 1 through 3. <br /> ' The C horizon has hue of 5Y through 10YR. <br /> COMPETING SERIES: This is the Abbott series. Abbott soils have more than 5 percent calcium <br /> tcarbonate equivalent throughout and lack gypsum crystals. <br /> GEOGRAPHIC SETTING: Apishapa soils are on flood plains or in slightly depressed areas on <br /> ' terraces. Slope gradients range from 0 to about 4 percent. The soils formed in alluvial parent <br /> materials derived from mixed rock sources. The average annual precipitation ranges from 6 to 15 <br /> inches, of which 8 to 10 inches falls during the months of April through August. The frost-free <br /> ' season is 140 to 170 days. <br /> GEOGRAPHICALLY ASSOCIATED SOILS: These are the Limon, Las, Las Animas and <br /> Haverson soils. Las Animas,Las, and Haverson soils have less than 35 percent clay in the particle <br /> size control section. Limon soils are well drained. <br /> ' DRAINAGE AND PERMEABILITY: Somewhat poorly drained or poorly drained; very slow <br /> runoff or ponded; slow permeability. <br /> USE AND VEGETATION: These soils are used principally as native hay or pastureland. Native <br /> vegetation is mainly saltgrass, alkali sacaton, western wheatgrass, brush cactus, and greasewood. <br /> DISTRIBUTION AND EXTENT: Eastern and southeastern Colorado and northern New Mexico. <br /> The series is of small extent. <br /> MLRA OFFICE RESPONSIBLE: Salina, Kansas <br /> SERIES ESTABLISHED: The Arkansas Valley Area, Colorado, 1926. <br /> National Cooperative Soil Survey <br /> U.
