'Mont Ross' is a
stratovolcano, the highest mountain in the
Kerguelen Islands at 1,840 m. It is located in the Massif Gallieni range, at the end of the Gallieni peninsula on the main island of Grande Terre. The volcano is composed primarily of trachybasalt and was active during the late
Pleistocene.
Mont Ross was named after explorer Sir
James Clark Ross. The mountain was first climbed in 1975 by Jean Afanassieff and Patrick Cordier, the last French mountain to be climbed.
