Red River of the South - USA
The Red River rises in the high plains of eastern New Mexico, and flows southeast across Texas and Louisiana to join the Atchafalaya River northwest of Baton Rouge, which then flows south to the Gulf of Mexico. The Mississippi and Atchafalaya rivers are connected by lock and dam close to the mouth of the Red River. The Red River is 1,200 miles long and gets its name from its reddish silt. It is navigable for 234 miles but most traffic is in the lower 36 miles where the scenery alternates between remote bottomland woods and the occasional towns such as Alexandria and Natchitoches, Louisiana. This lower section of the Red River and Atchafalaya basin flows into some of the most striking swampland in the country.
