Bozon died in 1964 at age 31 in a mountain climbing accident near Mont Blanc. He and 13 climbing companions were killed in an avalanche on the Aiguille Verte, a 4,122-metre (13,524 ft) mountain in the Mont Blanc massif.[6] The climbing party had reached an elevation of about 2,700 m (9,000 ft) when the avalanche occurred.[5] Bozon's father, Charles, Sr., had died on the same slope in an avalanche in 1938.[7]
