Author: Henry Bizot, France, AAC. Climb Year: 2010. Publication Year: 2011.

On September 19, during Argentina’s dry 2010 winter, in the remote and little-visited Cordillera Ansilta, located 250km north of Mendoza and 50km from Barreal, Gabriel Fava (Argentina) and I climbed a new route on Ansilta 4 (5,116m).

From base camp (3,950m) we hiked along a moraine toward the mountain; early in the walk, in the Morillos hills, we found fantastic caves with ancient paintings. We continued to the base and climbed the 750m southeast ridge (French D in these dry conditions, 55° max), beginning with a 400m ice face and followed by 350m of mixed terrain to the summit. In the absence of previous known ascents, we named the route Seis Hermanos, dedicated to my six boys.
