Arroyo de la Vibora

 (Spanish for Brook of the Viper) is a location featured in Red Dead Redemption.

Description
The small stream is located on the island of Guarma and runs into the bay known as Bahía de la Paz. Furthermore, it works as a natural border between Cinco Torres and La Capilla, areas under control by the rebels, and Aguasdulces, the only significant settlement on the island and the headquarter of Alberto Fussar.

Trivia

 * The stream might have gotten its name due to its shape. Another possibility is that there are, or used to be, an abundant amount of snakes in the stream.
