Cordillera de Colangüil, Cerro de la Quebrada Seca. A group from the nearby city of San Juan was active in this mighty and relatively untrodden zone in mid-January 2002, having as a goal the highest summit, Cerro del Lavadero (6122m). They took the Rio Lavadero route, but bad weather prevented them getting higher than 5,000 meters. They did ascend four virgin 4000m peaks, the highest of which was the Cerro de la Quebrada Seca (4735m).
