Mont Marion-Dufresne

Mont Marion-Dufresne is the highest peak in the Crozet Islands, rising 1,050 meters (3,445 feet) above sea level. The mountain displays volcanic features and dominates the landscape of these remote islands in the southern Indian Ocean.

The peak was named after French maritime explorer Marion Dufresne, who led expeditions through southern seas during the 1700s. The discovery of this island group became part of France's expansion into the remote southern ocean regions.

Scientists work in research stations near this summit to study subantarctic life and track climate changes happening in the southern hemisphere. Their findings help us understand how these remote regions connect to global environmental patterns.

Visiting this mountain requires permission from French authorities and passage on specialized vessels departing from Reunion Island. The extreme location and rough seas mean visits are only possible under specific conditions.

This peak sits at 46 degrees south latitude, placing it directly in the path of the Roaring Forties, powerful westerly winds that sweep across the southern ocean. These intense winds shape the weather patterns and environment of this remote location year-round.
