Diego Nakamura and partners have climbed many spires in the Sosneado Group over the past few years. The zone lies on the east flank of Cerro de los Pantanos, southeast of Cerro el Palomo (4,850m), along the Chile-Argentina border. In March, Lucas Alzamora and Diego Nakamura ascended the last virgin spire: Torre Blanca de Ectelion. They christened their route Chaparral (10 pitches, 475m, 6b). The route climbs a long rib just right of a prominent, steep gully. It is mostly 5+/6, but also contains a few meters of 6b climbing. They descended from the summit by a scree slope. This was their fourth attempt on the spire, with three previous attempts up a route left of the gully.
