4-60 <br />Collection of site-specific information included the excavation, <br />description, sampling and analyzing of major soil series, and <br />included man-made fill and other disturbed materials. Soil <br />series were sampled and described by virtue of backhoe pits <br />excavated to 60 inches or to bedrock, whichever was shallower. <br />Each genetic horizon of each major soil was sampled and described. <br />Dian-made fill was sampled and described from grab samples taken <br />at the surface. Soil map units were refined to include approxi-. <br />mate percentages and types of inclusions. Sampled pedons were <br />located on the soil map (Figure 4.7-1). Mapping, sampling, and <br />detailed soil descriptions were made in accordance with the <br />National Cooperative Surveys (USDA-Soil Survey Staff, 1975; <br />USDA-Soil Survey Staff, 1955). Soil analysis was conducted by <br />• F & L Labs, Fort Collins, Colorado. <br />From this information and site specific data, the major soils <br />to be affected in the study area were evaluated as a source of <br />material available for reclamation. The present and potential <br />uses of the major soils were evaluated for croplands, pasturelands, <br />and rangelends. <br />C~ <br />J <br />
