Nevado Tres Cruces
Nevado Tres Cruces is a volcanic massif in the Andes Mountains on Argentina's border with Chile. It has three main summits: Tres Cruces Sur at 6,748 meters (22,139 feet) and Tres Cruces Centro at 6,629 meters (21,749 feet), as well as Tres Cruces Norte at 6,206 meters (22,206 feet) (20,361 ft). The Andes' Tres Cruces Sur is the sixth highest peak.
Nevado Tres Cruces has a long history of activity, with at least 1.5 million years of eruptions. The complex is surrounded by lava domes and has several craters on its tops. The main volcano is rhyodacitic in nature and has erupted twice in the last 1.5 million years, the first 1.5 million years ago and the second 67,000 years ago. The most recent eruption was 28,000 years ago, but the volcano is a contributing source for a Holocene eruption and could erupt again in the future.
