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.
