` 3 <br />largely composed of shales, claystones, sandstones and major coal beds. <br />Occasionally, Upper Tertiary intrusive rocks are visible protruding from the <br />sedimentary bedrocks (Tweto 1979). Soils in the area are highly variable. The <br />soils differ with vegetation communities and elevation. High elevation soils are <br />often dark brown, large-grained, sandy looms, with high humus content in the <br />upper horizons. Lower elevation soils are lighter in color and contain much more <br />silt and very little or no humus. <br />The area is dominated by two vegetation communities, the Oak-Shrubland <br />community and the Sagebrush community. Higher elevations are occupied by the <br />Oak-Shrubland community. This community is dominated by gambel oak (Quercus <br />gambelii), Rocky Mountain maple (Ater glabrum), and curlleaf mountain mahogany <br />(Cercocarpus ledifolius). Trees found in association with these shrubs include <br />aspen (Populus tremu]oides), limber pine (Pious flexilis), and Douglas fir <br />(Pseudotsuga menziesii). Vegetation of the Oak-Shrubland community is often very <br />thick and dense, therefore visibility is often very poor. <br />The Sagebrush community is found in the lower elevations of the project <br />area. Dominant shrubs include low sagebrush (Artemisia arbuscula), rabbitbrush <br />(Chrysothamnus viscidiflorus), and bitterbrush (Purshia tridentata). Many <br />species of grasses and fortis accompany the shrubs, including western wheatgrass <br />(Agropyron smithii), wildrye (Elymus cinereus), and tansy mustard (Descurainis <br />Sophia). Visibility within this community is highly variable ranging from 50Y <br />• to 907.. Generally ground surface visibility was good, but ranged to poor at <br />times in densely vegetated areas. <br />Existing Data and Literature Review <br />A file search was conducted through the Office of Archaeology and Historic <br />Preservation (OAHP) in Denver on August 11, 1992, which revealed ten previous <br />surveys in the nearby areas. Eight surveys were block surveys, five under 30 <br />acres and three large surveys over 200 acres. The large surveys include the <br />Rockcastle Coal Company Mine Permit conducted by Kalia Archaeological Services <br />covering 200 acres south of the project area, the Hayden Gore Pass 345 KV <br />Transmission Line conducted by Grand River Institute covering 1,454 acres east <br />of the study area, and the Yoast Coal Mine conducted by Western Cultural Resource <br />Management, Inc. covering 1,413 acres south of the study area. <br />These surveys resulted in the discovery of five prehistoric sites and two <br />historic sites. All prehistoric sites are categorized as lithic scatters. Both <br />historic sites are categorized as homesteads. None of these sites are located <br />within the study area. <br />The West Central Colorado Prehistory is classified in five stages. <br />Paleoindian, Archaic, Formative, Proto-Historic/Historic and the Euro-Americ.n <br />Tradition (Guthrie et al. 1984; Reed 1984). The Paleoindian stage dates from <br />10,000 to 5,500 B.C. and is usually represented in the form of isolated finds and <br />occasionally associated with early prehistoric sites. The Paleoindian stage is <br />• characterized by the hunting of extinct megafauna and other large game. These <br />activities are often represented in the archaeological record by unique, large <br />projectile points. <br />
