Glacier Blanc

Glacier Blanc is an ice field in the Pelvoux range within Écrins National Park, stretching from high mountain slopes down through a wide valley. The frozen mass creates a stark white surface against the darker rock and scree of the surrounding peaks.

In the early 1800s, this ice field was connected to its neighboring glacier, forming a continuous expanse of frozen ice across the valley. Over time, warming temperatures have caused the two to separate and shrink.

The Glacier Blanc serves as a critical research site for scientists studying climate change impacts on Alpine glacial systems in France.

The main approach is a hiking trail starting from a valley parking area that climbs steadily toward the ice field. Weather conditions can change quickly in the mountains, so proper equipment and an early start are helpful.

Unlike its neighboring glacier, this ice field has a clean white surface because rock debris does not cover it. Visitors crossing or viewing the glacier notice how this bright appearance sets it apart from the darker neighbor.
