Cotahuasi canyon


Cotahuasi Canyon near the city of Arequipa in Peru is the deepest canyon in the world. The canyon is an impressive chasm that the river has eroded between two enormous mountain massifs: the Coropuna (6,425 m or 21,079 ft ASL) and the Sulimana (6,093 m or 19,990 ft ASL). One extends from spurs of the snow-covered Sulimana to the confluence with the Ocoña river. Cotahuasi Canyon was cut by the Rio Cotahuasi, a tributary of the Rio Ocoña, to a depth of approximately 3354 meters - over twice the depth of the Grand Canyon.

It is formed by the Cotahuasi River, arising at more than 4,750 m (15,580 ft) ASL in the lake Wansuqucha. It receives the tributaries of the Wayllapaña river in the neighborhood of Pampamarka, to the north, and the Huarcaya near Tumipampa, to the west, and is later joined by the Maran River to form the Ocoña River (Chaucalla village) that ends at the Pacific Ocean.

This province is characterized by its steep relief: incised by rivers and gullies, ranging between 1,000 and 6,093 metres, with 19 ecological zones. As is the case with cultures all over the world, the people of highland Arequipa Province are also changing with the times. Nonetheless, the altitude and remoteness of this region mean that residents have retained many of the practices that are now no longer common in neighboring regions.

Access

The only road leading to the canyon goes through Chuquibamba in the Condesuyos province, then Aplao in Castilla Province. It begins on the Panamerican Highway near Arequipa. Four bus companies start daily from the Arequipa bus terminal, between 4 and 6 pm. The bus drive is 10–12 hours long, on a road which is unpaved after Chuquibamba. It also goes quite high, through a 4500m pass between Coropuna and Sulimana.

The Cotahuasi Subbasin is a landscape park set up by a 2005 decree. It covers 1,212,175 acres (76x50 miles). This natural reserve preserves an integrated environment where man and nature are living in close harmony, in a preserved cultural microcosm. The difficult topographic conditions have generated specific landscapes like agricultural terraces.

Agriculture

Organic agriculture includes many plants in the reserve : kiwicha, quinoa, mint, dark maize, llacon, fava, oca, beans, arveja (pea), chulpi maize, anise, tarwi. These products are meant to give priority to food supplies to the province. Therefore, very little is produced for export. Food autonomy is reached thanks to ecological techniques, rational use of water, promotion of improved seeds, conservation of biodiversity, strengthening of producer associations, and complementary livestock breeding.

Tourism

The Cotahuasi landscape reserve is a preserved area. The landscapes have a large biodiversity including many endemic medicinal plants : muña, retama, tara, coca, jara (malva sylvestris), ruda (ruta graveolens), kiwicha, yareta (azorella compacta).

The landscapes are quite many, from the rivers at the bottom of the canyon to the cold desert areas of the summits. There are 12 different ecosystems in Cotahuasi reserve. There are also a number of Inca and pre-Inca works including the many agricultural terraces still in use today. The region is also rich with culture and traditions, preserved by ancient Andean people : weaving, colonial churches, inca tracks, numerous festivals.
