Trekking To Source Of Amazon River And Climbing To The Summit Of Nevado Mismi
Nevado Mismi is a 5,597m (18,358ft) mountain peak of volcanic origin located in the Andes mountain range of Arequipa, Peru. A glacial stream on the Mismi was firmly identified as the most distant source of the Amazon River in 1996 by scientist expeditions; this finding was confirmed in 2001 and again in 2007. The waters from Nevado Mismi flows into the Quebrada Carhuasanta and Apacheta, which flow into the Río Apurímac which is a tributary of the Ucayali which later joins the Marañon to form the Amazon proper.
Nevado Mismi is about 160km west of Lake Titicaca and 700km southeast of Peru's capital city, Lima, in the Arequipa Region. It is one of the highest points of Colca Canyon. There are several glaciers on the peak as Quehuisha, Huilcayo and Choquecorao. Their defrosting forms a small lagoon near the summit which is known as Laguna Inti Cocha (in ancient Quechua language meaning “sun lagoon”).
From Arequipa is possible to get to Mismi Mt by private 4x4 or rarely public bus passing through Chivay (Colca valley), Canocota and Tuti. The distance to drive is not more than 200km.
In the summit of Mismi it happens a "Divortium aquarium": The waters of their defrostings are divided and take two-way traffic: On the one hand they go away towards the Pacific Ocean (Through river Colca, Majes and Camaná) and by the other side towards the Atlantic Ocean (Through river Apurimac, Ene, Ucayali and Amazonas).
Quebrada Carhuasanta is at 4.900 meters high (16,072 ft.); in the beginning the small river is called Lloqueta, then Challamayo and finally Hornillos River (This we can see it in the road to Caylloma); after few kilometers Hornillos join its waters in “La Angostura” with Apurimac River (or Caylloma that comes from Vilafro lagoon. In its route the Apurimac receives waters of many tributary rivers that contribute to increase considerably their volume more and more impressive. When joining itself with the Apurimac in La Angostura and being a greater river goes towards Cusco, soon will cross the departments of Apurimac, Ayacucho, and part of Junin until arriving in Loreto to continue his fabulous trip towards Brazil.
MISMI MOUNTAIN EXPEDITIONS
The Cousteau Amazon Expedition: In 1982 Jean Michael Cousteau led a large scale scientific exploration of the Amazon from its mouth to its origin. The “Cousteau Amazon Expedition” cost eleven million dollars and culminated in a six-hour television documentary titled “Cousteau’s Amazon” released in 1983. It offered study information to last years and gave insights into the biology and geology of the largest river system on earth. Traditionally, explorers and geographers defining the origin of a river system by tracking the longest tributaries while heading upstream, as volume can change dramatically from month to month. In a system as complex as the Amazon basin with dozen of streams as candidates in previously poorly mapped areas, no consensus could plausibly be substantiated for some time, and the origin was left to speculation. Half a dozen sites claimed title to “The Origin of the Amazon River“ and until 1982 several were in the running.
Using an international team of twelve and bringing in expeditionary specialists from Germany, France, Argentina, Peru and the USA, Jean-Michel Cousteau put together resources and logistics spanning a thousand miles of unknown jungle.
The Upper Amazon expedition (The Flying Expedition) included an Eastern European multi-axle reticulated Land Rover for use on land, a float plane Papagaiu, for air support and reconnaissance, and the Peruvian Air Force offered a high elevation helicopter to reach the upper levels of the Cordillera de Chila Mountain range in Peru.
Expedition support bases were established in Cusco, in the mountains, in Arequipa near of the Pacific coast, and high in the Cordillera de Chila at Caylloma for the quest to find the origin of the Amazon River. Many locations were remote, making it necessary to surmount language, terrain and logistical difficulties, as the mountain team made their way up the Río Selinke to the flanks of Nevado Mismi. At this mountain's base, Jean Michael dispatched a team of German alpinists who climbed the 18,000 foot volcano and returned in two days. During their descent, they found melt water dropping into a fissure. This cleft varied from two meters to half a meter wide, angling down the slope. This stream flowed nearly fifty meters before disappearing, emerging again lower down to flow between stones and continues its course. They discovered that within the fissure, the water was deep enough to float a small craft and realized that they were presented with an opportunity. Utilizing pack llamas, kayaker Caril Ridley was brought to the site, and in June 1982, navigating by kayak, became the first person to run the origins of the Amazon. Later expeditions refined our understanding of the river's many origins and its subsequent course to the Atlantic Ocean.
National Geographic Society Expedition: In 2001, it was verified that the main headwater of the Amazon River has its glacial source on Nevado Mismi. An expedition of the National Geographic Society discovered that Carhuasanta stream flowing into Río Apurímac originates on the mountain's northern slopes and then runs its course through other tributaries and rivers to help form the main Amazon River. The fact that the headwaters of Río Apurímac are the source of the Amazon River was confirmed by Brazilian scientists in 2007, who pointed at Quebrada Apacheta as the most probable source of Rio Amazonas.
PERU ADVENTURE TOURS thanks to other expeditions not mentioned in this page. Thanks to those expeditions the region of Mismi Mt is getting more popular for mountain climbers and hikers coming to visit all these remote places located on the heart of the Andes of Peru.
