Continued- <br />With reference to Exhibit A, a topographical map <br />of the area, the soils generally found above 'the <br />approximate elevation of 6450 feet have char,scteristics <br />different from the soils;;tfielow this elevation. <br />In the area above this elevation the subsurfa~:e <br />material is predominantly Precambrian Crystal.7ine <br />Rock, which is exposed to the surface through~~ut <br />most of the area. The exposed rock is in vari~~us <br />stages and sizes of disintegration. This <br />disintegrated rock forms the bulk of the overburden. <br />Where surface soils do exist they are mixed with <br />the disintegrated rock, and the fine material:a are <br />iorganic clayey fine sands or silts with slig~~t <br />plasticity. The depth of the overburden vari~=s <br />from virtually nothing on the ridges to a depth <br />of up to six feet in a few pockets along the <br />drainage channels. <br />In the areas below the 6,450 foot elevation t.5e <br />subsurface materials are,from the West to East, <br />materials from the Fountain Formation, Lyons <br />Sandstone Formation and the Lykins Formation, <br />and each formation is intermixed with thin ba.uds <br />of either inorganic or organic clays. These <br />formations are exposed to the surface at randum <br />throughout the area. The surface materials ar° <br />generally inorganic micaceous silty soils or <br />inorganic clays with medium to high plasticity. <br />These soils cover the area in a generally uniform <br />thickness of two to eight inches, and in some <br />places are mixed with disintegrated crystalliue rock. <br />13 i. No effort was made to indicate the type, character, <br />and density of present vegetation covering the area <br />on any of the Exhibits. The present vegetation is <br />a sparse covering of native grasses, some low <br />growing sagebrush and buckbrush, and a few isolated <br />stands of willow bushes and scrub oak trees. A <br />landscape architedt has provided us with a list of <br />grasses, shrubs and trees for revegetation. <br />13 j. No effort was made to indicate the depth of the <br />crystalline rock in the extraction area, because <br />gelogical information indicates that the depth is <br />unlimited. <br />13 k. Exhibit B indicates the expected <br />of the area to be mined and the <br />affected, which is correlated to <br />Item 12 above. <br />14.
