Map Unit Description (Brief, Generated) <br /> Las Animas County Area, Colorado, Parts of Huerfano and Las Animas Counties <br /> [Minor map unit components are excluded from this report] <br /> Map unit: AC - Ayon-Capulin complex, 3 to 25 percent slopes <br /> Component: Ayon (50%) <br /> The Ayon component makes up 50 percent of the map unit. Slopes are 3 to 25 percent. This component is on fan <br /> remnants, lava plateaus. The parent material consists of alluvium and/or colluvium derived from basalt. Depth to a <br /> root restrictive layer is greater than 60 inches. The natural drainage class is well drained. Water movement in the <br /> most restrictive layer is moderately high_ Available water to a depth of 60 inches(or restricted depth)is very low. <br /> Shrink-swell potential is low. This soil is not flooded. It is not ponded. There is no zone of water saturation within a <br /> depth of 72 inches. Organic matter content in the surface horizon is about 2 percent. This component is in the <br /> R070XY07000 Basalt Breaks ecological site. Nonirrigated land capability classification is 6e. Irrigated land <br /> capability classification is 6e. This soil does not meet hydric criteria. The calcium carbonate equivalent within 40 <br /> inches, typically, does not exceed 50 percent. There are no saline horizons within 30 inches of the soil surface. <br /> Component: Capulin (45%) <br /> The Capulin component makes up 45 percent of the map unit. Slopes are 3 to 7 percent. This component is on <br /> fan remnants on lava plateaus. The parent material consists of colluvium and/or alluvium derived from basalt. <br /> Depth to a root restrictive layer is greater than 60 inches. The natural drainage class is well drained. Water <br /> movement in the most restrictive layer is moderately high. Available water to a depth of 60 inches(or restricted <br /> depth)is moderate. Shrink-swell potential is moderate. This soil is not flooded. It is not ponded. There is no zone <br /> of water saturation within a depth of 72 inches. Organic matter content in the surface horizon is about 2 percent. <br /> This component is in the R070XY071 CO Basalt Loam ecological site. Nonirrigated land capability classification is <br /> 6e. Irrigated land capability classification is 6e. This soil does not meet hydric criteria. The calcium carbonate <br /> equivalent within 40 inches, typically, does not exceed 18 percent. There are no saline horizons within 30 inches <br /> of the soil surface. <br /> Map unit: AnB - Ascalon sandy loam, 0 to 3 percent slopes <br /> Component: Ascalon (85%) <br /> The Ascalon component makes up 85 percent of the map unit. Slopes are 0 to 3 percent. This component is on <br /> plains, interfluves. The parent material consists of sandy eolian deposits. Depth to a root restrictive layer is <br /> greater than 60 inches. The natural drainage class is well drained. Water movement in the most restrictive layer <br /> is moderately high. Available water to a depth of 60 inches (or restricted depth) is moderate. Shrink-swell <br /> potential is low. This soil is not flooded. It is not ponded. There is no zone of water saturation within a depth of 72 <br /> inches. Organic matter content in the surface horizon is about 2 percent. This component is in the R067BY024CO <br /> Sandy Plains ecological site. Nonirrigated land capability classification is 4c. irrigated land capability classification <br /> is 3e. This soil does not meet hydric criteria. The calcium carbonate equivalent within 40 inches, typically, does <br /> not exceed 10 percent. There are no saline horizons within 30 inches of the soil surface. <br /> Survey Area Version:19 <br /> Survey Area Version Date:09/23/2016 Page 1 <br />
