Pronghorn antelope in Gardiner, Montana Yellowstone’s Photo Collection. “Early accounts of pronghorn in Greater Yellowstone described herds of hundreds seen ranging through most major river valleys. These populations were decimated by 1900, and declines continued among remaining herds. On the park’s northern range, pronghorn declined from 500-700 in the 1930s to about 122 in 1968. By 1992 the herd had increased to 536.” Photo #50 by William S Keller / NPS
