The figure-8-shaped area rising above the Patagonian Icefield at the upper left part of this NASA Landsat mosaic is part of the Viedma volcanic complex. An outflow glacier descends into Lake Viedma at the lower right. This mostly subglacial volcano produced an eruption in 1988 that confirmed the presence of a postulated subglacial vent in the Patagonian Icefield NW of Viedma Lake. The 1988 eruption deposited ash and pumice on the icecap and produced a mudflow that reached Viedma Lake.

Nunatak del Viedma is seen from Paso del Viento with Cordón Mariano Moreno partially hidden within the clouds. The huge lateral moraine of Viedma Glacier lies in the foreground. The glacier surface displays three conspicuous irregular tephra bands distorted by differential movement of the glacier.
