Straton and Charlet climbed together for twenty years and eventually married. Some of the ascents they made together included the Aiguille du Midi, the Aiguille de Blaitière, the Dents du Midi, and the Dom. In 1875 they made the first ascent of a peak on the Aiguille de Triolet, which Charlet named Pointe Isabella. This peak actually has two summits joined by a small ridge. The northern peak in high and is the usual one that is climbed. They climbed a new peak in the Aiguilles Rouges in 1881, which they named Pointe de la Persévérance in honour of the perseverance that they had shown before they had dared to confess their affection for one another.
