Saskatchewan is part of the Western Provinces and is bounded on the west by Alberta, on the north by the Northwest Territories, on the north-east by Nunavut, on the east by Manitoba, and on the south by the U.S. states of Montana and North Dakota. Saskatchewan has the distinction of being the only Canadian province for which no borders correspond to physical geographic features (i.e. they are all parallels and meridians). Along with Alberta, Saskatchewan is one of only two land-locked provinces.
