Slopes in <br />the area range from nearly level along the Yampa River to moderately and extre- <br />mely steep in the main portion of the study area. The majority of the soils <br />have dark colored surface layers greater than 16 inches thi.ck_overlying clayey <br />and loamy subsoils or sandstone at 40 to 60 inches. Extremely steep south- and <br />east-facing ridges have weakly developed soils with high rock fragment contents <br />and sandstone or shale at 10 to 30 inches. <br />Map 5 shows the distribution of soils in the study area. This information <br />is based upon unpublished preliminary soil mapping and soil legends prepared by <br />the Soil Conservation Service prior to April 1978. <br />• <br />Where mapping was incomplete and in areas requiring additional site speci- <br />fic soil analyses, additional soil mapping has been performed by ERT Inc. of <br />Fort Collins, Colorado (formerly ECI Inc.); by Bruce Morgan, consulting soil <br />scientist; and by Ertec Rocky Mountain Inc. <br />During the period of the initial mapping program, the main body of the <br />Meadows mine was disturbed, with vegetation removed and topsoil scraped and <br />stockpiled. Dominant soil units that occurred in the area prior to mining were <br />Routt loam (2VD) and Winevada-Unnamed (X8D and X8F). Winevada-Unnamed soils <br />(X8D and X8F) are the dominant soils in the undisturbed portions of the mine <br />area. Although it is easily accomplished, the aerial extent of the former soils <br />within the mine area is of little consequence now that they have been disturbed <br />by mining activities. <br />u <br />- 109 - <br />(Rev. 5/86) <br />
