Background

The volcanic field occupies a low-lying area between the southern end of Ensenada Cayutué, the southern extension of Lake Todos los Santos, and the northern end of the Estuario Reloncaví, where the Río Petrohué, which drains lake Todos los Santos, reaches the sea.
La Viguería and Volcán Cayutué are the principal cones. Formation of La Viguería cone and associated lava flows temporarily dammed the Río Petrohué about 3000 years ago, forming an ephemeral lake that was filled with deposits from Calbuco and Osorno volcanoes.
Pyroclastic cones and lava flows of Volcán Cayutué filled the Ensenada de Cayutué depression, separating Lake Todos los Santos from Ralún Bay.
