Above the Jas Lacroix hut, the Chanteloube valley opens up to the right in the form of a cirque. The highest peak in the cirque is the Verdonne point, which rises to 3328m. Sometimes a glittering object can be seen at its summit. This a Grand Réseau Radio des Alpes (GRA) radio relay station, serving the mountain rescue network. It is used to make radio contact with police and emergency services in Briançon.
