Nebraska is a state on the Great Plains of the midwestern United States. The State's capital is Lincoln and its largest city is Omaha, on the Missouri River.
Once considered part of the Great American Desert, Nebraska is now a leading farming and ranching state. The Omaha and Ho-Chunk (Winnebago) are federally recognized American Indian tribes, each with a reservation in Thurston County in eastern Nebraska, where they constitute the majority of the population. 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.
Two major climates are represented in Nebraska: the eastern half of the state has a humid continental climate, and the western half of the state has a semi-arid climate. The entire state experiences wide seasonal variations in temperature and precipitation.
