Description

The Illinizas massif is located in the Western Cordillera, at the western end of the Tiopullo node. It is formed by two inclined peaks that rise above 5000 meters and were once supposed to be part of an ancient volcano already extinct long ago. Etymologically, the south peak should be called Illiniza and the north one Tioniza; words originated from the Atacameño and which respectively mean “male hill” and “female hill”. Currently we called them referring to their cardinal position: “Illiniza Sur” and “Illiniza Norte”. Both mountains are separated by a depression called “La Ensillada”, which refers to a saddle. The New Horizons Refuge is located at this place, second in antiquity in Ecuador, named in honor of the Mountain Club "Nuevos Horizontes". This refuge was opened in 1965 at the foot of the South Illiniza rock walls (and ice). The south peak with its 5266 meters has historically had glaciers on all its flanks; but due to global warming it has lost many of them, and those remaining have been constantly reducing its size. Recent years technical analyzes indicate that the current rate of global warming will dry it up completely in the coming decades. The north peak with its 5139 meters is composed mainly of sand and rocks, despite having a height just below its companion, has not had glaciers for more than a century.

Recommendations

  • Usually, a single day is used for climbing to the Illiniza Norte summit (departing from Quito at dawn). For the Illiniza Sur, it is usually required two days, staying overnight in the New Horizons refuge.
  • If you don't have private transportation, it is convenient to rent a pickup-truck taxi at Machachi or El Chaupi central squares or markets, it will be easy to find them, the cost will be around US $ 20 one way for up to 6 persons from Machachi. They usually take you until "La Virgen" parking lot, approximately 4000 meters high, where the hike to the refuge begins. It's also possible to get these pickup trucks at the "Hotel La Llovizna" at Chaupi in about US. 10 one way. Buses goes from Machachi to El Chaupi every 30 minutes departing at the Machachi market place, "Cooperativa EL CHAUPI", 0.75 dollars.
  • The Illinizas Ecological Reserve opening hours are from 8am to 3pm every day of the year. The exit is at most 5pm.
  • It is necessary to register and sign a discharge certificate in the reserve access control. The record confirms that you are the only one to blame for your horrible and reckless acts; and in case of generating an accident you will have to assume all the rescue costs, or your relatives must do it.

Volcanology

There is little information or geological studies about the Illinizas; however it is known that the Illinizas are the remnant of an early or middle Pleistocene volcano; it is thought that the current summits formed the flanks of a large and opened caldera whose center was located to the west. They have layers of lava and pyroclastic material arranged alternately, which determines their characteristic of stratovolcano, best seen in the Illiniza Sur. Currently the volcano is extinct, even though many people report they have smelled sulfur at some places near the high rocks.
