Resumen / Abstract.

The Southern Patagonia Icefield remains one of the least studied glacial areas in the world, although it is one of the largest mid-latitude ice bodies. The largest glacier, Glaciar PíO XI, located on the western maritime side, has been advancing during the last 50 years. In 1993 the tidewater front of the glacier was overriding trees at least 300 years old.
