<br />Soil Survey Maps <br />The distribution of each soil map unit on the New Horizon Mine study area for 1988,1996 and 1998 <br />is provided as a composite on Map 2.04.9-1 <br />Typifying soil pedons (soil sample locations), as well as soil profile description locations are also <br />denoted on Map 2.04.9-1. A complete soil identification legend, which identifies all mapping unit <br />symbols, is as Attachment 2.04.9-1. A soil classification legend that identifies the taxonomy of each <br />named soil component is Attachment 2.04.9-2. A Taxonomic unit description of each named soil <br />component is provided as Attachment 2.04.9-3 at the end of this section. Soil profile data sheets <br />are found in attachment 2.04.9-10. <br />Soil Survey -1998 <br />• The soil test location descriptions are typical and consistent for soil in the area. The Order I survey <br />is a refinement of the "not yet published" Order III soil survey that the NRCS has conducted in the <br />area. Detailed map unit descriptions can be found in Appendix2.04.9-9, Soil Map Unit Descriptions. <br />Map unit 98A occurs on alluvial terraces formed along Tuttle Creek. Profiles were described to 72 <br />inches. Some areas may have soil deeper than 72 inches and yield a slightly greater amount of <br />salvage material. <br />Map unit 986 occurs on steep mesa side slopes. Hardness of bedrock varies depending on the <br />underlying strata. Coarse fragments range from channers to cobbles and are residual and colluvial <br />in nature. Valleycity soil has the same physical and chemical properties as those soils similarly <br />named in the survey area. Valleycity is outside the range of characteristics compared to the survey <br />area, in that it occurs in an area of 5 to 8 inches mean annual precipitation. <br />Map unit 98C occurs on mesa summits, ridges and crests. Hardness of bedrock varies depending <br />on the underlying strata. <br />• <br />(Revised march zoos) 2.04.9-16 <br />
