• sandy clay loam. Groundwater is at a depth of 13 to 26 inches. The Torrifluvents are not recommended for lift 1 material because they lack a mollic epidedon. They are suitable for lift 2 material to a depth of 6U inches or snore. A groundwater table may be encountered and the so it snag be difficult to salvage due to wetness. This soil occurs in map unit TA. It was sampled in typical pedon number 6 and in composite sample numbers 236/270. Average lift 1 thickness is U inches, average lift 2 thickness is 6U+ inches, for an average total salvagable thickness for the series of 6U+ inches. 2.1.15 Torriorthents Tnis soil is a shallow to deep, well drained, slowly to rapidly permeable soil formed in colluvium derived from sandstone and' shale. It occurs on south facing mountain sideslopes on slopes of 2U to 7U percent. The native vegetation is bunchyrasses and sage. The available water holding capacity is low to moderate. In a typical profile, the surface layer is brown to dark brown,. channery loam about 5 inches thick. The subsoil is light brownish gray to olive brown, very channery clay about 44 inches thick: The substratum is gray, weathered calcareous shale. Uepths to bedrock range from 3 inches to over 60 inches, but most are lU to 60 inches. The soil is mostly within the loamy-skeletal and clayey-skeletal, mixed families of Lithic and Ustic Torriorthents. The Torriorthents are quite variable. The surface layer of the Torriorthents are suitable for lift 2 material, but the subsoils are unsuitable due to excessive channery. This soil occurs in map unit TRD. It was sampled in typical pedon number 27 and in composite sample numbers 201/231 Average lift 1 thickness is U inches, average lift 2 thickness is 14 inches, for an average total salvagable thickness for the soil 14 inches. 2.1.16 Vandamore Var. Flaygy Sandy Loam This soil is a moderately deep, well drained, moderately permeable soil formed in residuum derived from sandstone and shale. It occurs on narrow upland ridgecrests and mountain sideslopes on slopes of 5 to 55 percent. The native vegetation is big sage, serviceberry and mountain shrubs. The available water holding capacity is moderate to low. In a typical profile, the surface layer is very dark grayish brown to dark yellowish brown, flaggy sandy loam or sandy clay loam about 6 inches thick. The substratum is yellowish brown, cobbly clay to very cobbly loam about 18 inches thicK. Depth to bedrock is 2U to 4U inches. The series is in the loamy-skeletal, mixed (calcareous) family of Typic Cryorthents. Depth to bedrock averages 2U inches. The profile is generally calcareous throughout. Surface cover is about 2U percent flagstones. 15
