The Kerguelen Islands lie in the South Indian Ocean in a triangle formed by Australia, Africa, and Antarctica. At 1,850 m, the islands' highest point is Mount Ross, capped by a white glacier in this satellite image. Glaciation is also evident in the jagged fjords cut into the islands. The Kerguelen Islands, a territory of France, consist of one main island surrounded by about 300 smaller islands. Photo courtesy of NASA.
