Le Donjon, Mountain summit in Kerguelen Islands, French Southern and Antarctic Lands.
Le Donjon is a mountain summit in the Kerguelen Islands that rises 594 meters above sea level in the southern Indian Ocean. Its steep rocky slopes bear the marks of constant fierce winds that shape the exposed surfaces year-round.
The summit received scientific attention during the first French expeditions to the Kerguelen Islands in the late 18th century for geographical mapping purposes. These early missions established the foundation for later research into the geological and atmospheric conditions of this remote region.
Scientists from international research stations regularly monitor the summit area to study climate patterns and geological formations in sub-Antarctic environments.
Access requires official permits from French authorities and specialized equipment due to year-round extreme weather conditions in the region. The journey is demanding because of the remote location and harsh ocean conditions in the southern Indian Ocean.
The summit area contains specific volcanic formations that provide geological evidence about the formation processes of the Kerguelen archipelago.
