Prior to 1994, the big game survey area included the permit area; atwo-mile perimeter to the west, north, and east of the mine; and a three-mile perimeter to the south. That survey area totaled approximately 35 miZ. In 1994, the survey area was expanded to gather regional data. That same area was surveyed in 1995. The expanded survey area totaled approximately 84.5 miz and extended from Seneca II-W Mine on the west to the Seneca Mine on the east (Exhibit 1). The entire survey area is in the brushy foothills of the Williams Fork Mountains, south of the Yampa River. Elevations over the area range from 6100 feet in the north to over 8300 feet above sea level in the south. Steep slopes and high ridges covered with mountain brush characterize the topography and vegetation of the expanded area. Aspen (Populus tremu[oides) stands are scattered throughout the area, but mainly occur along the upper reaches of drainages. Isolated stands of fir are found at the iv95 s~ i[-w M'vu etg came Aerial sunny Page ~
