Nebraska is a state on the Great Plains of the Midwestern United States. Its state capital is Lincoln. Its largest city is Omaha, which is on the Missouri River.
The state is crossed by many historic trails, but it was the California Gold Rush that first brought large numbers of non-indigenous settlers to the area. Nebraska became a state in 1867.
There are wide variations between winter and summer temperatures, and violent thunderstorms and tornadoes are common. The state is characterized by treeless prairie, ideal for cattle-grazing, and it is a major producer of beef, as well as pork, corn, and soybeans.
The state is bordered by South Dakota to the north; Iowa to the east and Missouri to the southeast, across the Missouri River; Kansas to the south; Colorado to the southwest; and Wyoming to the west. The state has 93 counties; it occupies the central portion of the Frontier Strip. Nebraska is split into two time zones.
The Central Time zone comprises the eastern half of the state, while the western half observes Mountain Time. Three rivers cross the state from west to east. The Platte River, formed by the confluence of the North Platte and the South Platte, runs through the central portion of the state, the Niobrara River flows through the northern part, and the Republican River runs across the southern part.
Nebraska is composed of two major land regions: the Dissected Till Plains and the Great Plains. The easternmost portion of the state was scoured by Ice Age glaciers; the Dissected Till Plains were left behind after the glaciers retreated. The Dissected Till Plains is a region of gently rolling hills; Omaha and Lincoln are in this region.
The Great Plains occupy the majority of western Nebraska. The Great Plains region consists of several smaller, diverse land regions, including the Sandhills, the Pine Ridge, the Rainwater Basin, the High Plains and the Wildcat Hills. Panorama Point, at 5,424 feet (1,653 m), is the highest point in Nebraska; despite its name and elevation, it is a relatively low rise near the Colorado and Wyoming borders.
A past Nebraska tourism slogan was "Where the West Begins"; locations given for the beginning of the "West" include the Missouri River, the intersection of 13th and O Streets in Lincoln (where it is marked by a red brick star), the 100th meridian, and Chimney Rock. Nebraska is a triply landlocked state, as it does not border the ocean, nor do any of the states it borders, nor any that they border.
