Mountrail County is a county in the northwestern part of North Dakota, United States. As of the 2020 census, the population was 9,809.[1] Its county seat is Stanley.[2] The county was originally created in 1873, then removed in 1892, annexed by Ward County. It was re-created and organized in 1909.[3][4] The county is home to the headquarters of the Three Affiliated Tribes of the Mandan, Hidatsa, and Arikara people, and a large part of the county belongs to the tribe's Fort Berthold reservation.[5][6]

History

[edit]

The Dakota Territory legislature created the county (as Mountraille County) on January 4, 1873, with area annexed from Buffalo County. The origin of its name came from Joseph Mountraille, a locally famed Metis voyageur and mail carrier from Pembina under Norman Kittson's employment.[7][8] The county was not organized at that time, nor was it attached to another county for administrative or judicial purposes. The new county lost territory in 1885 when a portion was annexed off to create Garfield County (now extinct). This situation continued until February 21, 1891, when Mountrail County was attached to Ward County, for "judicial and other purposes". The following year (November 8, 1892), the North Dakota legislature voted to dissolve the county and have its territory absorbed by Ward County.

An election held in Ward County on November 3, 1908, authorized the re-creation of Mountrail County, although with different boundaries than the previous county proposal. The countywide vote totals were 4207 to 4024, but the result was contested in court. On January 16, 1909, the state Supreme Court upheld the vote,[9] so the county government was organized on January 29 of that year.[4][10][11]

Oil production from the Bakken formation in the early 21st century attracted workers and reversed decades of population decline in the county. From 2010 to 2015, especially, population markedly increased, creating its own strains.

Geography

[edit]

The Missouri River flows southeastward along the SW boundary line of Mountrail County, and Shell Creek drains the lower central part of the county into the Missouri, discharging at Shell Creek Bay. The terrain consists of rolling hills, largely devoted to agriculture. Its NE portion is dotted with ponds and lakes.[12] The Laurentian Divide runs east–west through the central part of the county, with the northern areas sloping to the north and the southern areas sloping to the south. Its highest point is on the upper west boundary line, at 2,480 ft (760 m) ASL.[13] The county has a total area of 1,942 square miles (5,030 km2), of which 1,825 square miles (4,730 km2) is land and 116 square miles (300 km2) (6.0%) is water.[14]

Mountrail County is one of several western North Dakota counties with significant exposure to the Bakken Formation in the Williston Basin.
