Glacier d'Ossoue

Glacier d'Ossoue is located in the Vignemale massif along the French-Spanish border, stretching roughly 1.4 kilometers at about 2,760 meters elevation. The ice field displays visible signs of erosion from meltwater and exposure to weather.

The ice field was once significantly larger, covering a much greater area during the 19th century than it does today. Since then, the ice mass has steadily diminished due to climate changes.

The caves carved into the glacier walls by mountaineer Henry Russell serve as visible markers that show how the ice has shifted and changed over the years.

The best time to visit is during warmer months when there is less snow and the trails are easier to walk. The route from Ossoue Dam is well marked and requires hiking experience and proper gear.

In recent decades the ice has retreated dramatically and loses mass year after year. This change is visible on the ground and gives visitors a direct view of how climate change affects glaciers.
