What is the border of Saskatchewan?

the northern sea board
=================
Saskatchewan is a landlocked province. It does not have any "sea board."

To the west, Saskatchewan is bordered by Alberta, to the north by Northwest Territories, to the east by Manitoba, and to the south by portions of the US states of Montana and North Dakota.

Saskatchewan's southern border is the 49th parallel of latitude. Its northern border is the 60th parallel of latitude. Its western border is 110°W longitude (also known as the 4th meridian).

From the 60th parallel, the eastern border of Saskatchewan follows the 2nd meridian (approximately 102°W) south approximately one-third of the distance to the 49th parallel. After that, it comprises a series of "steps" (called a "correction line") until it intersects the US border at 101°30'W.
