North Dakota is a landlocked state in the Upper Midwest.

Grassland and farm fields cover most of North Dakota, where the average elevation is 1,900 feet (580 m) above sea level.

North Dakota has few named islands due to the lack of water bodies.

Following the damming of the Missouri River, some islands were flooded and ceased to exist.

[3] They were located in the Missouri River before the water level was raised by the construction of the Oahe Dam and the Garrison Dam by the United States Army Corps of Engineers.
