• regolith up to 30 feet in depth, these soils are formed in place of Precambrian bedrock <br /> materials or glacial moraine deposits. Cation Exchange Capacity (CEC) in these soils is <br /> moderate to high with surface textures that are generally gravelly fine sandy loams. <br /> The coarse character of Soil No. 13 is readily apparent in the project area, where rock <br /> and gravel may be present as a large percentage of the profile at or near the surface. <br /> The surface horizons are considered well-drained. <br /> Topography <br /> The PC3 Conveyor will be constructed on variable topography covering 21,553 linear <br /> feet of ground over the existing Henderson railroad grade and US Forest Service lands <br /> adjacent and west of the railroad grade to the Henderson Mill Ore storage bins. The <br /> first 7,400 linear feet of conveyor will be constructed along the existing Henderson <br /> Railroad grade. Newly affected lands will range in elevation from 9,025 feet MSL at <br /> • station 184+55 above the East branch Reservoir to 9,372 feet MSL at station 118+50 <br /> on the west aspect of a local promontory. Beginning and ending elevations of newly <br /> affected lands are 9,092 feet and 9,175 feet MSL respectively. <br /> Aspects associated with the newly affected land for the construction of PC3 are <br /> generally west and southwest. There are relatively short segments of the conveyor <br /> route that face south-southeast (-1,100 linear feet) or north-northwest (-900 linear feet) <br /> over slopes ranging from near level to 40%. Aspect shows a marked influence on <br /> vegetation for southern exposed slopes but is less influential on vegetative cover for <br /> north and northwest facing slopes. <br /> • <br />
