Glaciar Ojo del Albino, Mountain glacier in Tierra del Fuego, Argentina.

Ojo del Albino Glacier lies in the Sierra Alvear, about 20 km northeast of Ushuaia, and covers 86 hectares. Its front moraine dams a round lagoon filled with floating ice blocks, and meltwater from the ice feeds the Laguna Esmeralda.

The glacier received its name in 1989 from a local trekking guide who chose it based on the milky white color and round shape of the lake. Over decades, the ice mass has shifted and water once flowed through different valleys before reaching its current course.

The name "Ojo de Albino" was given in 1989 by Gustavo Giorgis, a guide with the Ushuaia trekking agency Caminante, after the lake's milky white colour and round shape. Most visitors reach the glacier along the trail through the Tierra Mayor valley toward Laguna Esmeralda.

The hike takes a full day and requires sturdy footwear with good grip and waterproof gear for the damp, cold mountain environment. Visitors should prepare for steep climbs and know that weather can change quickly in the mountains.

A paleochannel shows that until a few decades ago the glacier's main drainage ran toward the Beban valley, parallel to the Esmeralda basin, before shifting to feed Laguna Esmeralda. The lagoon itself was much smaller when Gustavo Giorgis named it in 1989; meltwater has since enlarged it to its present round shape.
