The Colorado River (Spaingie: Río Colorado) is ane o the principal rivers o the Soothwastren Unitit States an northren Mexico (the ither bein the Rio Grande). The 1,450-mile (2,330 km) Colorado River drains an expansive, arid wattershed that encompasses pairts o seiven U.S. an twa Mexican states. Stairtin in the central Rocky Moontains in the U.S., the river flows generally soothwast athort the Colorado Plateau an throu the Grand Canyon afore reachin Loch Mead on the ArizonaNevada border, whaur it turns sooth taewart the internaitional border. Efter enterin Mexico, the Colorado approaches the maistly dry Colorado River Delta at the tip o the Gulf o Californie atween Baja California an Sonora.
