The first recorded account of a body reappearing from a glacier in the Mont Blanc range was made by Viscount Edmond de Catelin in 1861. It concerned three alpine guides who were buried in a crevasse during an avalanche on 20 August 1820 near the Rocher Rouges, high up on Mont Blanc, during an expedition organised by Joseph Hamel. Forty years later the remains of two of them were discovered, re-exposed within fissures in the Bossons glacier. They were lower down from the point where they were lost; the corpse of the third guide was discovered the following year. In 2014, a group of climbers found a body on the Glacier du Talèfre, close to the Couvercle Hut. It was identified as that of a young Chamonix guide who had been caught in a winter storm during a solo ascent of the Nant Blanc face of the Aiguille Verte in 1982 and was assumed to have fallen into a crevasse. In 2013, a box of valuable gemstones was found by a climber on the Bossons Glacier. It had re-emerged, having been carried downhill from the site of one of two Air India plane crashes. These occurred at almost identical locations high up near the summit of Mont Blanc: one in 1950 (Air India Flight 245), and one in 1966 (Air India Flight 101). Debris from these crashes is still commonly found on the glacier below.
