This series occurs in map units JBB and JBC. It was sampled in <br />typical pedon number 19 and in composite sample numbers 88/6U and <br />lU4/129. Average lift 1 thickness is 12 inches, average lift 2 <br />thickness is 41 inches, for an average total salvagable thickness for <br />the series of 53 inches. <br />2.1.5 Lamphier Loam <br />This soil is a very deep, well drained, moderately to rapidly <br />permeable soil formed in colluvium derived from sandstone. It occurs <br />on steep mountainsides on slopes of 12 to 5U percent. The native <br />vegetation is yrasses and mountain shrubs. The available water <br />holding capacity is high. <br />In a typical profile, the surface layer is black loam about 7 <br />inches thick. The subsoil is dark brown, clay loam or sandy clay loam <br />about "LU inches thick. The substratum is yellowish brown, clay loam <br />to gravelly clay loam about 33 inches thick. Depth tc bedrock is <br />greater than 60 inches. The series is in the fine-loamy, mixed family <br />of pachic Cryoborolls. <br />The mollic epipedon averages 34 inches thick. The thick mollic <br />epipedon is very good as a lift 1 material. The subsoils are also <br />mostly good for lift 2 but are fair to marginal in some pedons due to <br />finer textures. • <br />This series occurs in map unit LRU. It was sampled in typical <br />pedon number 23 and in composite sample numbers lUl/65 and 'L65/195. <br />Average lift 1 thickness is 34 inches, average lift 2 thickness is 26+ <br />inches, for an average total salvagable thickness for the series of <br />6U+ inches. <br />2.1.6 Nihill Channery Loam <br />This soil is a deep, somewhat excessively drained, moderately <br />permeable so it formed in colluvium derived from sandstone. It occurs <br />on fans in valley bottoms on slopes of 6 to 43 percent. The native <br />vegetation is mixed yrasses, big sage and low shrubs. The available <br />water holding capacity is low. <br />In a typical profile, the surface layer is dark brown to dark <br />yellowish brown, channery or gravelly loam about 7 inches thick. The <br />subsoil is dark brown to dark yellowish brown, gravelly to cobbly <br />loam, sandy clay loam, or clay loam about 53 inches thick or more. <br />Depth to bedrock is greater than 6U inches. The series is within the <br />loamy-skeletal, mixed (calcareous), mesic family of Ustic <br />Torriorthents. <br />Tne profile is typically calcareous throughout. Ghanners and <br />j cobbles are 25 to 40 percent by volume. The Nihill is not recommenced • <br />for lift 1 because it lacks a mollic epipedon, but the soil is rates <br />suitable for use as lift 2 material to an average depth of 38 inches. <br />Some profiles will have excessive coarse fragments at depth and should <br />not be used. <br />lU <br />
