Cerro Tuzgle, Stratovolcano in Susques Department, Jujuy Province, Argentina

Cerro Tuzgle is a dormant stratovolcano in the Susques Department of Jujuy Province, northwestern Argentina, reaching 5,486 metres. It rises about 1.2 km from terrain at roughly 3.7 km elevation and has a 0.5-square-kilometre platform at its summit. Three east-west fissure vents in the summit area fed dark lava flows that ran southward and southwestward, flanked by 1–2-metre scoria ridges; a well-preserved flow descends the southern flank.

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", describing the volcano's shape; it is also written Tujle, Tugle or Tugler. The summit area was reached by a road built for trucks in 1939, when sulfur was mined at Mina Betty on the northwestern flank between 5,000 and 5,350 metres.

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.

On the northwestern flank, between 5,000 and 5,350 metres, lie the abandoned sulfur mines of Mina Betty, where seven sulfur outcrops were reported in 1939. A truck road built at that time reached the summit area, and the mines are visible from the south-southwestern flank.
