ENGLISH: Río Maranon is the mainstem source of the Amazon River and flows through a canyon comparable in many ways to the Grand Canyon of the Colorado in Arizona. It is also home to many of the Awajún nation (an Amazon tribe) and others living in picturesque villages along the upper canyons such as Calemar, the site of Ciro Alegría's famous novel La Serpiente de Oro. Due to its unique status as the source of the largest river in the world and its other outstanding attributes, the Maranon merits protection from a series of >12 hydroelectric dams that are planned along the river.
