Abstract

Paleoglacial features that occur in central Chiloé are characteristic of an ice-sheet style of glaciation, which differentiates it from a typical Alpine glacial style defined previously for the Chilean Lake District (CLD). Therefore, the Archipiélago de Chiloé represents a geographical break point where the Patagonian ice sheet (PIS) became the large ice mass that occupied the Patagonian Andes during the last glacial period (Llanquihue Glaciation). A double ice-contact slope on the east face of the Cordillera de La Costa provides evidence for the most extensive Early Llanquihue glacial advance on Isla Grande de Chiloé. The most prominent LGM advance in the area occurred at 26 000 cal yr BP, coincident with regional stadial conditions, and is defined by a big moraine along the east coast of the island
