North Dakota ( ) is a state located in the Midwestern and Western regions of the United States of America. North Dakota is the 19th largest state by area in the US; it is the 48^th most populous, with just over 640,000 residents as of 2006. North Dakota was carved out of the northern half of the Dakota Territory and admitted to the Union as the 39^th state on November 2, 1889.

The Missouri River flows through the western part of the state and forms Lake Sakakawea behind the Garrison Dam. The western half of the state is hilly and contains lignite coal and oil. In the east, the Red River forms the Red River Valley, holding fertile farmland. Agriculture has long dominated the economy and culture of North Dakota.

The state capital is Bismarck and the largest city is Fargo. The primary public universities are located in Grand Forks and Fargo. The United States Air Force operates bases at both Minot and Grand Forks.

Geography

main: Geography of North Dakota

The western half of the state consists of the hilly Great Plains, and the northern part of the Badlands to the west of the Missouri River. The state's high point, White Butte at , and Theodore Roosevelt National Park are located in the Badlands. The region is abundant in fossil fuels including crude oil and lignite coal. The Missouri River forms Lake Sakakawea, the third largest man-made lake in the United States, behind the Garrison Dam.

The central region of the state is divided into the Drift Prairie and the Missouri Plateau. This area is covered in lakes, slough, and rolling hills. The Turtle Mountains are located along the Manitoba border. The geographic center of the North American continent is located near the city of Rugby.

The eastern part of the state consists of the flat Red River Valley, the bottom of glacial Lake Agassiz. Its fertile soil, drained by the meandering Red River flowing northward into Lake Winnipeg, supports a large agriculture industry. Devils Lake, the largest natural lake in the state, is also found in the east.

Climate

main: Climate of North Dakota North Dakota endures temperature extremes characteristic of its continental climate; with cold winters and hot summers, the record low and high temperatures are and respectively. Meteorological events include rain, snow, hail, blizzards, polar fronts, tornadoes, thunderstorms, and high-velocity straight-line winds. Depending on location, average annual precipitation ranges from 14 in (35.6 cm) to 22 in (55.9 cm).

Springtime flooding is a relatively common event in the Red River Valley, due to the river flowing north into Canada, creating ice jams. The spring melt and the eventual runoff typically begins earlier in the southern part of the valley than in the northern part. The most destructive flooding in eastern North Dakota occurred in 1997, which caused extensive damage to Fargo and Grand Forks.
