The group is located in the northwestern area of the archipelago. It lies about north-west, across the Jean-Baptiste Charcot Channel, from the tip of the
Loranchet Peninsula, the northernmost extension of Grande Terre, the principal island of the Kerguelens. The islands are of
volcanic origin. The main islands of the Nuageuses are Île de Croÿ, Île du Roland, Île d’Après and the Îles Ternay, with the small Île Clugny some to the south of the others. Far to the north lies the
Îlot du Rendez-vous. The highest point in the group is just over 500 m above sea level and the coastlines are mainly sheer cliffs. There is one lake on the archipelago, Lac Claudine, measuring 400 sq m. ==History==
