Driven by social networks, the popularity grows of the mountain Seven Colors made
In August 2017, for example, Vinicunca appeared in the list of the hundred places that you should know before dying compiled by the website Business Insider
The explosion in local tourism is recent, but the history of the mountain and its beautiful colors began for millions of years.
Oxidation of Minerals
The colors that decorate mountain slopes result from "a complex geological history, with marine, lacustrine and fluvial sediments," according to a report from the US Department of Transportation. Cultural Development of the Cusco Cultural Directorate
These sediments, transported by the water that once covered the whole place, date from the Tertiary and Quaternary periods, or there are 65 million to 2 million years [19659002] Over time, the sediments formed layers (with grains of different sizes) that now form the colored fringes.
The movement of the tectonic plates of the region elevated these sediments until 39, they became what is now the mountain.
Gradually, the different layers have acquired their striking colors.
According to BBC News, the geologist César Muñoz, member of the Geological Society of Peru (SGP) [19659015] explained to BBC News that the result of the oxidation of different minerals – due to the humidity of the area – Based on a study of the Office of Cultural Landscaping and from his own research, Muñoz explained the composition of each of the layers, according to the color:
– Pink or fuchsia: mixture of red clay, mud and sand.
– White: sandstone (quartz sand) and limestone
– Purple or lavender: marl (mixture of clay and calcium carbonate) and silicates
– Red: argillites and clays
] – Green
– Yellowish brown, mustard or gold: limonites, limestone rich in sulfurous minerals (combined with sulfur)
Fabián Drenkhan, researcher at the Po Institute of Nature Sciences said that these mixtures also contain iron oxides, usually reddish in color.
Disclosure by Social Networks
But if these flashy colors already decorate the mountain
Articles published by the Peruvian and international media suggest that Vinicunca would have been discovered because climate change would have melts the snow that covered it.
However, geologists consulted by
Juan Carlos Gómez, of the Geophysical Institute of Peru (IGP), said that the mountain was only partially covered with ice and that it was receiving snow temporarily until the early 1990s.
Fabián Drenkhan, meanwhile, said that he did not believe that the summit had been a glacier in recent decades or decades.
"I have no evidence of what happened to this mountain and would be very cautious in baderting (that climate change has left Vinicunca uncovered.)
The inhabitants of Pitumarca say that it does not exist. There has been no snow for 70 years, according to Haydee Pacheco, secretary of tourism.
Pacheco explains that the mountain has gained popularity thanks to the tourists who pbad by there to go to Ausangate, a sacred hill for the inhabitants of Cusco
Colombian magazine Semana attributes Vinicunca's success to the disclosure made by Instagram users Facebook, which has attracted crowds of tourists
