Urubamba River
The Urubamba River, also known as the Vilcamayo River, is a significant watercourse in Peru, serving as a partially navigable headwater of the Amazon River. Originating in the Andes Mountains, the river plays a crucial role in the geography and history of the region.
Geographic Origin and Course
The Urubamba River rises on the slopes of Cunurana in the Puno Region, Melgar Province, near the La Raya Pass. It follows a north-northwest course for approximately 724 kilometers (450 miles) before merging with the Tambo River to form the Ucayali River. This confluence acts as a critical junction within the vast Amazon Basin.
Upper and Lower Urubamba
The river is divided into two distinct sections: the Upper Urubamba and the Lower Urubamba. The dividing landmark between these sections is the Pongo de Mainique, a dramatic whitewater canyon where the river constricts to a mere 45 meters (148 feet) in width.
Upper Urubamba
The Upper Urubamba, or Alto Urubamba, is characterized by a densely populated valley with extensive agricultural irrigation systems. This area is renowned for its historical significance, featuring numerous ruins from the Inca Empire. Notable archaeological sites include the world-famous Machu Picchu, Patallaqta, Pikillaqta, and Raqch'i. The Sacred Valley of the Incas, through which the river flows, is a vital historical region, reflecting the ingenuity and cultural heritage of the ancient Incas.
Lower Urubamba
The Lower Urubamba continues beyond the Pongo de Mainique into more remote and less populated areas. This section of the river is known for its natural beauty and biodiversity, offering a habitat for various species within the Amazonian ecosystem.
Economic and Cultural Importance
The Urubamba River is integral to both the natural and cultural landscapes of Peru. It supports local agriculture and communities, and it is pivotal for projects such as the Salcca-Pucara hydroelectric project. The river also facilitates communication and transportation for remote communities, particularly in the Megantoni District of the La Convención Province.
Notable Events
Historical events of interest include the tragic accident involving Carlos Fitzcarrald, a key figure in rubber baron history, who drowned on the river alongside his business partner, Antonio Vaca Díez.
