Seno Otway

Seno Otway is a large inland sound lying between Brunswick Peninsula and Riesco Island in southern Chile. Alternatively called Otway Sound, this natural waterway occupies a valley blocked by a large terminal moraine left by the retreat of a glacier during the last glacial period. In spite of being located east of the Andes, it is connected to the open Pacific Ocean through the Strait of Magellan via a narrow passage, which cuts into the Andean Massif. Seno Otway also is hydrologically connected with Seno Skyring by the Fitzroy Channel.
