Monthly changes in average group sizes of mule deer, white-tailed deer, and pronghorn antelope, January 1977-January 1978. remain similar to that during spring and summer. During the winter of 1977- 1978, concentrations of mule deer occurred in a hilly region between the North Fork of McGuire Creek and Prairie Elk Creek, and in an area of coulees and bad- lands south of Fort Peck Reservoir. Mule deer were not observed on the proposed mining area after December 20, 1977, and winter groups observed in the vicinity remained in rough breaks areas north and south of the proposed mining area. Mule deer density estimates were based on winter 1977-1978 aerial survey data. These were the best data available, since snow cover of 95-100%, cold temperatures, and clear skies contributed to good aerial visibility of mule deer during this survey. Minimum population counts of 532 mule deer on the reconnaissance area and 55 on the mine study area were obtained, giving minimum density estimates of mule deer/km2 () and mule deer/km-^ ( mi2) for the two areas,respectively. Scattered groups were observed in the northern half of the reconnaissance area, giving a minimum density estimate of mule deer/km^ () for this area; the southern half supported more mule deer with a minimum density estimate of ( ). 103.
