Artesonraju Glacier, Peru Retreat & Lake Development
Artesonraju Glacier is a 3.3 km long glacier in the Cordillera Blanca of Peru drains west from Nevado Artesonraju. It is fed by steep heavily crevassed slopes. The glacier feeds both Lake Artesonraju, a new lake that formed after 1930 and Lago Paron. The two lakes are dammed by glacier moraines and together have posed a hazard of a glacier dammed lake outburst. In 1951 an outburst of water and alluvium …

Yanashallasa Glacier Retreat, Peru
Yanashallasa Glacier is near the southern end of the Cordillera Blanca in Peru. The glacier feeds the Rio Santa river, which provides irrigation for substantial agricultural acreage. Marks and Seltzer (2003) identify that at least 30% of the runoff comes from glaciers, rising considerably during the dry season. The glacier retreat in the region with a 22% area loss from 1970-2003 (Racoviteanu et al , 2008), will lead to continued …

Quebrada Carhuascancha Glacier Retreat, Peru
Quebrada Carhuascancha Glacier is in the Cordillera Blanca of Peru, draining the northeastern slopes of Huantsan. A glacier lake outburst flood was reported in the valley in 1965 from a landslide into one of the lakes. The region has experienced ongoing glacier loss with Racoviteanu et al (2008) noting a 22% loss in area from 1970-2003 in the Cordillera Blanca. They further observed an average rise of terminus elevation by …

Llaca Glacier Retreat, Peru
The Cordillera Blanca, Peru has 27 peaks over 6,000m, over 600 glaciers and is the highest tropical mountain range in the world. Glaciers are a key water resource from May-September in the region, Mark (2008). The glaciers in this range have been retreating extensively from 1970-2003, GLIMS identified a 22% reduction in glacier volume in the Cordillera Blanca. Vuille (2008) noted that the retreat rate has increased from 7-9 meters …
