Ice avalanches |
|
|
Description |
A great ice-collapse occurred at the beginning of November 1970 (probably the day 1st). The avalanche filled the gullies of the face under the snout, and spread on the debris-cone below, till reaching the stream coming from left snout of Miage glacier. |

Ice avalanches |
|
|
Description |
In the night between 24th and 25th June an enormous crevasse formed about 200 meters above the snout, in the glacier tongue: a huge ice mass moved downward, stopping in 20 meters, but a small part of it detached and fell, reaching the path between Freney huts and the Miage morain. The ice-avalanche covered a path of about 1300 m (in horizontal projection), and a differcence of altitude of about 730 m, reaching also Miage stream. Some ice-blocks were 3-5 m large, and ice cone had a maximum thickness of less than 20 m.

Note |
Probably, heavy rains occurred in the previous days, followed by night-frost with solidification of water in crevasses (and increasing of volume), had a part in the detachement. The water flowing on the bedrock probably favoured the sliding of ice too. |

Ice avalanches |

|
Description |
In the morning, several seracs fell from the snout of glacier. A part of the ice-avalanche stopped on the slope between the second and the first gradine, while the other part fell besides the first gradine, covering for 1/3 the debris-cone on the which the path for Gamba alpine hut winds. |
