sandy soils and cobbly profile occurring on site. The C horizon including weathered bedrock and <br />~~ gravel is encountered within 30-36 inches from the surface. <br />Soils that have been stripped to below the C horizon indicate that the pazent material has nutrient <br />availability and water holding capacity similaz to the developed profiles. Volunteer vegetation, <br />usually native grasses, with some perennials and shrubs, is present within those areas bladed <br />sometime since 1939. This volunteer vegetation suggests that even the parent material may be a <br />suitable plant-growth medium. <br />Site S~cific Soils <br />Four basic soil pedons occur on site. The first of these(map unit UF) is found on flat to very gently <br />sloping open grassy areas. The second pedon (map unit FA) is similar to map unit UF, but occurs <br />• under a forest canopy. Pedon three (map unit GO) exhibits chazacteristics quite different from those <br />of map units OF and FA. These soils have formed on very gravelly glacial outwash. <br />The fourth mapping unit (MS) are those areas that were disturbed during other periods of mining that <br />have potential for either fill material or a source of suitable plant growth material. Generally, this <br />mapping unit has resulted from the leveling of hill tops or ridges by bulldozers to allow for the easy <br />maneuvering or working of mining equipment. When these earlier disturbed soils were moved, the <br />parent material was exposed, and in some instances the column was side-cast, providing a suitable <br />and highly localized plant-growth medium source. These areas will be salvaged but they are not used <br />in calculating topsoil needs for the entire reclaimed site. <br />Map Unit OF <br />Atypical profile for this unit occurs in open areas where the dominant vegetation is the bunch grass <br />• Arizona fescue. In some areas encroachment of pine is occurring. Where protected and with <br />Alma Placer 7/03 67 <br />
