Onelli Glacier

Onelli Glacier is an ice formation in the Patagonian Andes that releases meltwater into Lake Argentino. The ice mass covers a large area and forms a white landscape surrounded by mountain peaks.

The glacier was named after an Italian scientist who came to Argentina in the late 1800s and studied the landscapes of this region. His work helped document the geological features of the Southern Patagonian Ice Field.

The glacier bears the name of an Italian scientist who studied Patagonia's ice formations and contributed to understanding this region. Today, visitors can observe how the local landscape is shaped by ongoing glacial processes and change.

The glacier is surrounded by a large lagoon best explored from the water. The best time to visit is during warmer months when weather conditions are more stable.

The Bolado Glacier was once connected to this ice formation but separated due to the continuous retreat of both ice masses. This separation shows the dramatic change these formations have undergone in recent decades.
