Yanteles, Stratovolcano in Los Lagos Region, Chile

Yanteles is an isolated stratovolcano in Corcovado National Park, Los Lagos Region, formed by five glacier-capped peaks along an 8 km NE-trending ridge. Its main summit, also called Volcán Nevado, reaches 2,042 m, and the edifice covers 84.5 km². A caldera with a pyroclastic cone lies on the volcano, and in 2007 its glaciers covered 46.24 km².

This volcano experienced a major eruption in ancient times that shaped its structure and the surrounding terrain. In recent decades, scientists documented minor steam emissions from vents, indicating the volcanic system remains geologically active.

The name Yanteles may refer only to the main summit, also called Volcán Nevado, Spanish for "Snow-covered Volcano". The volcano is little known and attested in a late 19th-century publication, and was recognised as a volcano by 1916. Its activity is monitored by the Observatorio Vulcanológico de los Andes del Sur (OVDAS), and part of its meltwater feeds the Canef river.

Yanteles lies in Corcovado National Park, in Chaitén municipality; the nearest settlements are Villa Santa Lucía and Bahía Tic-Toc, and Chaitén is 60 km away. Access is by boat or on foot, and the five glacier-capped peaks along the 8 km ridge are not a marked trail. SERNAGEOMIN classes it a type III volcano, so check current volcanic alerts before setting out.

The glacier systems on this volcano are shrinking noticeably and serve as an important indicator for climate shifts in Patagonia. Researchers monitor these ice masses closely to understand long-term environmental changes across southern Chile.
