Whymper Route, Chimborazo (6 310 m / 20 702 ft)

In 2008 the eruption of Tungurahua, which located 40 kilometers east of the Chimborazo, changed the conditions of all the routes to the Chimborazo. Ash and dust from the eruption covered the Chimborazo's slopes and caused severe melting of snow that turned it slopes in a glaciated shell. The most popular routes to Chimborazo immediately became much more difficult and more than 90% of climbers canceled their expeditions to the highest mountain of Ecuador.
