History
As first organized, the county occupied an extensive area, bounded on the north by Canada, southwest and west by the Missouri River, having Montana for a part of its northwest boundary, and comprising a large portion of the “Plateau du Coteau du Missouri,” and a part of the Miniwakan or Devil's Lake. While this does expand into modern-day North Dakota, this conundrum can be solved by realizing that the county was created in 1864, 25 years before the Dakota Territory was split into North and South Dakota.
