Slope County is a county in the U.S. state of North Dakota. As of the 2020 census, the population was 706, making it the least populous county in North Dakota and the 18th-least populous county in the United States. The county seat is Amidon.




History


The vote to create Slope County, by partitioning the lower portion of Billings, was held on November 3, 1914. This was the final (as of 2019) alteration to that once-large Dakota county, as Bowman had been partitioned off in 1883, and Golden Valley was split off in 1910. The unorganized Slope County was not attached to another county for administrative or judicial purposes during the interregnum; on January 14, 1915, the county organization was effected. The name refers to the Missouri Slope, a geographical feature that is also a popular designation for western North Dakota, particularly the area west of the Missouri River.




Geography



Slope County lies on the lower west side of North Dakota. Its west boundary line abuts the east boundary line of the state of Montana. The Little Missouri River enters the county's south boundary line from Bowman County near the Montana border and flows north until it loops very briefly into Golden Valley County. Then it flows east to near the midpoint of the north boundary of Slope County and then turns north into Billings County. Cedar Creek drains the southeastern portion of the county, flowing south into Bowman county.
Slope County terrain consists of semi-arid rough hills and gullies interspersed with lower hills, part of which is dedicated to agriculture. The terrain slopes to the east and south; its highest area (except for isolated prominences, such as White Butte) is its northwestern corner, at 3,104 ft (946 m) ASL. The county has a total area of 1,219 square miles (3,160 km2), of which 1,215 square miles (3,150 km2) is land and 4.2 square miles (11 km2) (0.3%) is water.
White Butte, the highest natural point in North Dakota at an elevation of 3,506 ft (1,069 m), is in southeast Slope County.
