The last glacial period and its associated glaciation is known in southern Chile as the Llanquihue glaciation (Spanish: Glaciación de Llanquihue).[1] Its type area lies west of Llanquihue Lake where various drifts or end moraine systems belonging to the last glacial period have been identified.[2][A] The glaciation is the last episode of existence of the Patagonian Ice Sheet. Around Nahuel Huapi Lake the equivalent glaciation is known as the Nahuel Huapi Drift.
The preceding interglacial is known as the Valdivia interglacial after its type locality of Valdivia.[4]
