Glaciar Vinciguerra y turberas asociadas, Mountain glacier in Tierra del Fuego, Argentina

Glaciar Vinciguerra is a mountain glacier in Tierra del Fuego surrounded by extensive peat bogs that shape the landscape. A turquoise meltwater lake forms at its base, creating a striking contrast against the surrounding vegetation.

The glacier was named after Italian zoologist Vinciguerra, who participated in a scientific expedition in 1882. This expedition contributed significantly to the geographic and biological exploration of this southern region.

The site was designated a Ramsar wetland on 16 September 2009 under number 1886, Argentina's 19th such site and the world's southernmost as of 2011. Its two wetland groups are the glacier with its lagoons, rock glaciers and permafrost, and the Andorra Valley peat bogs of Sphagnum and sedges.

The trail to the glacier is demanding and requires good physical preparation and proper equipment. Visitors should expect changeable weather and allow sufficient time for the hike.

The glacier has been studied by glaciologists since 2003 and is retreating markedly due to climate change. Its meltwater feeds the Laguna de los Témpanos, whose level can vary by up to 30 cm between morning and afternoon in summer, with peak meltwater flows of 1 m³/s; in winter the lagoon freezes over completely and runoff drops to 0.020 m³/s.
