Cay, Dormant stratovolcano in Aysén del General Carlos Ibáñez del Campo Region, Chile.
Cay is a dormant stratovolcano in the Aysén region that rises to about 2,090 meters (6,860 feet) in elevation. Its southwestern flank is marked by several smaller parasitic cones at lower altitudes.
The volcano formed at the intersection of major faults within the Liquiñe-Ofqui Fault Zone in the Andes. No volcanic activity has been recorded since the Holocene epoch.
Local mountaineering groups maintain records of geological activities and changes in the volcanic structure through regular documentation and research expeditions.
The volcano sits in a remote region and is accessible only with specialized transportation and experienced guides. Proper preparation and suitable equipment are essential for visiting.
The mountain displays a rare mixture of basalt and dacite rock formations that reflect its complex magmatic history. This geological diversity is uncommon in the Patagonian region.
