State Reg. <br />• etc.). Map unit names contained in the S.C.S, legend (1977) and used later <br />by Fly and Associates (1979) in the surrounding Seneca Mine disturbance <br />area were correlated to the 4-40's soils. The map unit boundary lines for the <br />4-40's area were transferred to high quality black and white stereo prints <br />that were flown July II, 1971. Soil boundaries were refined in an office <br />photo-interpretive study using a mirror stereoscope. The map units were <br />joined to the Claude Fly and Associates survey of 1979. The refined <br />mapping was then transferred to a revised and updated I" = 400' topographic <br />base map. Slope designations were rechecked from This base. <br />V. SURVEY RESULTS <br />Three soil series were identified within the 4-40's soil survey area (see <br />Exhibit 9-I).. These included X8:Winevada and SpliTro loam complex, 5 To <br />40% slopes and 66:Skylick clay looms, 5 to 40% slopes. The Winevada- <br />Splitro soils are shallow to moderately deep over sandstone bedrock. Small <br />. areas of sandstone outcrops and other localized regions of deep soil over <br />sandstone bedrock are included within this map unit. The Skylick soils are <br />deep and occupy drainages and concave slopes landscapes. They have <br />formed from mixed parent materials including fine-grained sandstones and <br />shales. They often have developed near the Wadge and Wolf Creek coal <br />outcrops. <br />Field soil profile in conjunction with laboratory analysis data are included <br />for the Splitro, Winevada, and Skylick soils (Tables 9-2-I through 9-2-5). <br />These pedon descriptions are very similar to those collected by Fly during <br />the 1977 Seneca Soil Survey (Tab 9). The major difference between the <br />three soils is the profile depth. The suitability ratings for individual soil <br />horizons are rated as good to fair (see Tab 9 for a more detailed description <br />of each quality). <br />VI. RECOMMENDED TOPSOIL SALVAGE DEPTHS <br />• Salvage depths for the 4-40's area soils will be identical to those <br />recommended by Fly and Associates for the surrounding Seneca Mine area <br />(see Tab 9, Alternate Table 6; Tab 9, Attachment I, Section II; and Topsoil <br />9-12 <br />
