Amalia Glacier, Tidewater glacier in Última Esperanza Province, Chile.

Amalia Glacier is a tidewater glacier in Última Esperanza Province that spreads across approximately 3 kilometers in width. It flows more than 20 kilometers from the Southern Patagonian Ice Field down to the Sarmiento Channel, forming a massive wall of ice where fresh ice meets the sea.

The glacier formed as part of the extensive ice coverage of the Patagonian region during the Ice Age. Since the mid-20th century, it has been retreating, with the terminus withdrawing roughly 7 kilometers between 1945 and 1986.

The glacier lies within Bernardo O'Higgins National Park, whose main visitor entry points are Puerto Natales, Villa O'Higgins, Caleta Tortel and Puerto Edén. The Skorpios cruise route through the Southern Ice Fields includes the glacier, and the most visited areas of the park are the glaciers at the head of Última Esperanza and the Pio XI glacier.

Visitors reach the glacier mainly by boat from the coast, with tours crossing the waters of Patagonia. The best conditions for viewing occur during calm weather, when the ice formations are most visible and snow-covered slopes stand out clearly.

Amalia Glacier is also called Skua Glacier, a name shared with the seabirds that nest in the area; the Spanish sources note the glacier is home to penguins and seabirds. It partially surrounds Reclus Volcano and erodes the volcano's northern flank, so the ice is actively quarrying the cone rather than merely encircling it.
