Volcan Aguilera, first ascent in Patagonia by the Uncharted expedition

PlanetMountain.com - The Uncharted expedition comprised of Camilo Rada, Natalia Martinez, Ines Dusaillant, Viviana Callahan and Evan Miles has made the first ascent of Volcan Aguilera (2480m) on the South Patagonian Icefield. Furthermore, during the return across the Hielos Continentales the team ascended four other previously unclimbed peaks. The report by Camilo Rada.
 
In their third Uncharted expedition, Camilo Rada (Chile) and Natalia Martinez (Argentina) teamed up with Ines Dusaillant (Chile), Viviana Callahan (Chile), and Evan Miles (USA) to accomplish the first ascent of the remote Volcan Aguilera, and managed first ascents of 4 other peaks during a 19-day crossing of the South Patagonian Icefield in the 2014 austral winter. The team’s primary objective, Volcan Aguilera (2480m) stands solitary 1500m prominent over the Icefield due west of the famed Falla Reichert, and was the last major Andean volcano without an ascent.

Although located only 10km from ocean access via Fiordo Peel, the approach’s dense vegetation and the region’s fickle weather had repulsed 6 previous month-long expeditions since 1986 (see historic background bellow), allowing only one team to even establish a camp at the mountain’s base. Taking note, the Uncharted team instead employed a counter-intuitive approach, starting from the Brazo Spegazzini of Lago Agrentino (Argentina) to traverse 47 km of icefield and opening new passes to arrive at the mountain’s untried north side. This entrance to the ice field was previously untried and proved to be a quick access to a wide area of poorly explored terrain. In a single 25-hour round-trip summit push, the team was able to negotiate the mountain’s towering seracs, gaping bergschrunds, and ice mushrooms to attain the summit at dusk on August 29th. Their route, Concierto de Rimayas, ascends the volcano’s north ridge before crossing onto the heavily-glaciated northwest face, and is named for the complex navigation required to find a path through the many fissures, passing around, over, and through at least 5 bergschrunds in variable weather including sun, snow, freezing rain, and wind.

Rest included exploration of volcanic formations on the mountain’s NE flank and a descent off the ice to vegetation while scoping future access routes from the nearby fjord. Then, taking advantage of extra rations and fantastic weather on their return journey, the team subsequently climbed 2 unnamed peaks (2420m, 2440m), Cerro Spegazzini’s East Peak (2290m), and Cerro Esperanza (2520m), all believed to be previously unclimbed.
 
The Uncharted project seeks to preserve exploration heritage and clarify errors and confusion in the exploratory history and maps of Patagonia’s mountain ranges, conducting extensive historical research and contacting members and family of prior expeditions before producing a high-quality topographic map highlighting the primary routes and correct peak names. Prior investigations and expeditions to the Cordillera de Darwin (2013) and the Cordillera de Sarmiento (2012) each resulted in significant ascents and corrections to geographic ambiguities. The Aguilera expedition has also identified several significant map errors for the seldom-visited region, and the team expects to clarify this confusion in their map after finishing their literature review. Read more..
