The Cook Glacier ( French Glacier Cook or Calotte glaciaire Cook ) is the largest ice cap of about France belonging Kerguelen -Archipels in the southern Indian Ocean and the largest glacier on French territory. It is located in the far west of the main island Grande Terre and covers an area of around 403 km². The highest point of the glacier, called Le Dôme , is 1049 m above sea level. The glacier is named after James Cook , who explored the archipelago on his third South Sea voyage in 1776.
The glacier has retreated significantly over the past few decades. From 1967 to 2003, the ice cap lost 20% of its area and 22% of its volume. The main reason for the retreat of the glacier is considered to be the significantly reduced annual rainfall.
