Cerro Tuzgle, Stratovolcano in Susques Department, Jujuy Province, Argentina
Cerro Tuzgle is a stratovolcano rising to 5,486 meters on the Puna plateau in Argentina's Jujuy Province. The volcano displays distinct lava flows running down its southwest and southeast slopes.
Volcanic activity began roughly 650,000 years ago, creating the Tuzgle Ignimbrite formation through large explosive eruptions. Subsequent lava dome eruptions shaped the mountain's structure over millennia.
The name Tuzgle comes from the Kunza language and means knoll, reflecting how indigenous peoples observed the mountain's shape. This naming reveals how local inhabitants understood and described the landscape around them.
Access is possible via Provincial Route 74, though visitors should prepare for high altitude conditions and bring suitable equipment. The isolated location requires advance planning for any on-site activities.
The mountain contains thermal springs with alkaline waters that flow year-round. These geothermal features offer potential for energy research and scientific study in this remote high-altitude region.
