The Cimarron River ( or Ñíhgu, meaning 'Salt River'; ) extends 698 mi across New Mexico, Oklahoma, Colorado, and Kansas. The headwaters flow from Johnson Mesa west of Folsom in northeastern New Mexico. Much of the river's length lies in Oklahoma, where it either borders or passes through eleven counties. There are no major cities along its route. The river enters the Oklahoma Panhandle near Kenton, Oklahoma, crosses the corner of southeastern Colorado into Kansas, reenters the Oklahoma Panhandle, reenters Kansas, and finally returns to Oklahoma where it joins the Arkansas River at Keystone Reservoir west of Tulsa, Oklahoma, its only impoundment. The Cimarron drains a basin that encompasses about 18927 mi2.

Names and etymology

The river's present name comes from the early Spanish name, Río de los Carneros Cimarrones, which is usually translated as 'River of the Wild Sheep'; previous English names for the river include Grand Saline, Jefferson (in John Melish's 1820 U.S. map), Red Fork, and Salt Fork.

Description

In northeastern New Mexico and in far western Oklahoma, the river is known as the Dry Cimarron River. The Dry Cimarron is not completely dry, but sometimes its water entirely disappears under the sand in the river bed. The Dry Cimarron Scenic Byway follows the river from Folsom to the Oklahoma border. The waterway becomes simply the Cimarron River after being joined by Carrizozo Creek just inside the Oklahoma border, west of Kenton, Oklahoma. Carrizozo Creek also originates in New Mexico and exits into Oklahoma before re-entering New Mexico and then returning to Oklahoma before joining the river. In Oklahoma it is further joined by North Carrizo Creek north-northeast of Kenton, Tesesquite Creek further to the east of Kenton, and South Carrizo Creek yet further to the east. It additionally joins with Cold Springs Creek, Ute Canyon Creek, and Flagg Springs Creek before crossing into Kansas. The river flows along the southern edges of Black Mesa, Oklahoma's highest point. As it first crosses the Kansas border, the river flows through the Cimarron National Grassland. At Guthrie, the river is joined by Cottonwood Creek (Cimarron River tributary), at a site known for frequent flooding. The Cimarron's water quality is rated as poor because the river flows through natural mineral deposits, salt plains, and saline springs, where it dissolves large amounts of minerals. It also collects quantities of red soil, which it carries to its terminus. Before the Keystone Dam was built, this silt was sufficient to discolor the Arkansas River downstream.

Early explorers

The first Europeans to see the Cimarron River were apparently Spanish conquistadores led by Francisco Vásquez de Coronado in 1541. The Spanish seem to have done little to exploit the area. The Osage tribe claimed most of the territory west of the confluence of the Cimarron and the Arkansas. In 1819 Thomas Nuttall explored the lower Cimarron and wrote a report describing the flora and fauna that he found there. In 1821 Mexico threw off Spanish rule and William Becknell opened the Santa Fe Trail.
