Kansas is a U.S. state in the Midwestern United States. Its capital is Topeka and its largest city is Wichita, with its most populated county and largest employment center being Johnson County. Kansas is bordered by Nebraska on the north; Missouri on the east; Oklahoma on the south; and Colorado on the west.
Kansas is bordered by Nebraska to the north; Missouri to the east; Oklahoma to the south; and Colorado to the west.
Kansas is underlain by a sequence of horizontal to gently westward dipping sedimentary rocks. A sequence of Mississippian, Pennsylvanian and Permian rocks outcrop in the eastern and southern part of the state.
Nearly 75 miles of the state’s northeastern boundary is defined by the Missouri River. The Kansas River (locally known as the Kaw), formed by the junction of the Smoky Hill and Republican rivers at appropriately-named Junction City, joins the Missouri River at Kansas City, after a course of 170 mi (270 km) across the northeastern part of the state.
The Arkansas River, rising in Colorado, flows with a bending course for nearly 500 mi (800 km) across the western and southern parts of the state. With its tributaries, (the Little Arkansas, Ninnescah, Walnut, Cow Creek, Cimarron, Verdigris, and the Neosho), it forms the southern drainage system of the state.
Kansas’s other rivers are the Saline and Solomon Rivers, tributaries of the Smoky Hill River; the Big Blue, Delaware, and Wakarusa, which flow into the Kansas River; and the Marais des Cygnes, a tributary of the Missouri River. Spring River is located between Riverton and Baxter Springs.
