• Exhibit "C" Descriation of Land to be Affected Geology A brief statement of general geology taken from the Seneca II report indicates that the surface exposures are chiefly upper Cretaceous sedimentary rocks of the Mesa Verde group overlain by Lewis shale. Other formations such as Lance, Fort Union, and Wasatch overlie these lower beds. Sandstones are dominant but certain shale beds give rise to tough clay soils such as the Aaberg and Binco series which have a very high content of clay. Vegetation At elevations of around 6000-8000 feet, the following general types occur in the drilling area: Aspen, Mountain Brush, and Sagebrush-grass. Briefly, these types may be described as: Sagebrush-grass - Types occurring on lower slopes and ridges dominated by low shrubs and big sagebrush (Artemesia tridentata); other species include • snowberry (Symphorocarpos sp) and fortis such as arrowleaf balsamroot (Balsamorhiza sagittata), lupines (Lupinus sp), clover (Trifolium), spring parsely, and prairie onion (Allium textile). Grasses make up a small percent of the total herbage. Mountain Brush - This is a major group on sandier soils, north and east slopes, and high ridges. Species include gambell oak ( uercus amg Belli), chokecherry (Prunus virginiana), Saskatoon serviceberry (Amelanchier alnifolia). Fortis include starwort (Stellaria crassifolia), western yellow (Achillea lanulosa), larkspur (Delphinium sp), and Fendler meadowrue (Thalictrum fendleri). Some grasses and sedges occur also. Aspen types - Occur on higher northfacing slopes or in pockets where snow collects, seeps provide additional moisture on protected perennial stream drainages at lower elevations. Forbs occur such as angelica (Angelica sp), false hellebore (Veratrum californicum), Columbine (Aquilegia sp), and delphinium. Grasses such as mountain brome may occur in patches.
