The Mont Blanc glacier flood was a damaging flood near Mont Blanc, France, that occurred in 1892. In the disaster, a subterranean glacial lake burst from beneath the Tête Rousse glacier[which?] on the mountain and released 200,000 cubic meters of water,[1] flooding the village of Saint-Gervais-Le Fayet[1] and killing 175 people.[2] The lake did not overflow because of too much accumulated water, but because there water-filled crevasse that shrank when the change to a positive mass balance of the entire glacier occurred beginning in 1878.[1]
