plateau in southwestern Manitoba, Canada, forming the highest part of the Manitoba Escarpment. It extends southeastward from the Saskatchewan border for 50 miles (80 km), culminating in Baldy Mountain (2,730 feet 【832 m】), 36 miles northwest of Dauphin. A large part of the plateau is embraced by Duck Mountain Provincial Park, established in 1962 to preserve the region's dense forests, numerous lakes, and abundant wildlife; both are named for the wild ducks found there.
