encountered at tlepth at ceriain times and in places the soil may be • difficult to salvage due tv wetness. This series occurs in map unit SA. It was samples in typical pedon number 3 and in composite sample numbers 196. Averaye lift 1 thickness is 4U inches, averaye lift 2 thickness is 2U+ inches, for an average total salva9able thickness for the series of 6U+ inches. 2.1.13 Thornburgh Cobbly Loam This soil is a deep, well drained, moderately to rapidly permeable so it tormed in alluvium and colluvium derived from sandstone. It occurs on uplands on slopes of lU to 65 percent. The native vegetation is ServlCeberry, big Saye and mountain shrubs, The ava ilable water holding capacity is moderate. In a typical profile, the surface layer is very Dark brown, cobbly loam about 12 inches thick. The substratum is yellowish brown, sandy loam to gravelly sandy clay loam about 48 inches thick. Depth to bedrock is yreater than 60 inches. The series is within the loamy-skeletal, mixed family of Typic Cryoborolis. The mollic epipedon averages 13 inches thick. Channers and cobbles range from 15 to 50 percent by volume. Coal stringers are common below 30 inches. The mollic epipedon is a good source of lif~ 1 material. The material from below the mollic epepedon to a depth 25 inches is suitable for lift 2. However, at a depth of about 25 inches, cobbles are excessive and the remaining subsoil is rated unsuitable salvage. This series occurs in map unit TCD. It was sampled in typical pedon number 9 and in composite sample numbers 124/148. Averaye lift 1 thickness is 13 inches, averaye lift 2 thickness is 12 inches, for an averaye total salvayable thickness for the series of 25 inches.. 2.1.14 Torrifluvents Gravelly This so it is a deep, moderately weld to somewhat poorly grained, moderately permeable soil formed in gravelly alluvium derived trom sandstone and shale. It occurs on valley bottoms on slopes of 3 to 33 percent. The native vegetation is bunchyrasses and wii-lows. The available water holding capacity is high. In a typical profile, the surface layer is very dark brown, gravelly loam about 4 inches thick. The subsoil is dark grayish brown, very gravelly to extremely gravelly sandy loam about 15 inches thick. The substratum is brown to dark Drown, gravelly.sandy clay loam about 37 inches thick. Uepth to bedrock is yreater than 6U inches. The soil is mostly within the loamy-skeletal, mixed families of Ustic Torrifluvents. The surface layer is loam, sandy clay loam or gravelly loam 4 t~ 7 inches thick. The subsoil is a gravelly to very gravelly sandy clay loam or stay loam.
