Glacier de Planpincieux, Alpine glacier in Courmayeur, Italy.

Glacier de Planpincieux is a mountain glacier on the southern face of the Grandes Jorasses, part of the Mont Blanc massif, above Courmayeur in the Aosta Valley. It sits on a steep rock wall and is visible from several points in the valley below.

Since 2013 the glacier has been closely monitored, with summer displacement rates of 30 to 50 cm per day. In September 2019, the mayor of Courmayeur ordered road closures and evacuated the risk zone below the glacier when about 250,000 cubic metres of ice threatened to break away. Access roads were closed again on 5 August 2020, when some 75 people were evacuated.

The glacier has become closely tied to local awareness of alpine hazards, with road closures and alerts now a familiar part of life in Courmayeur. Residents and visitors alike have grown used to watching for updates during warmer months when the ice is most unstable.

Before visiting, check current access conditions, as the road into Val Ferret can be closed when the risk of ice fall is high. Early morning tends to offer clearer views from the valley floor.

In summer 2021, the glacier moved up to 1.5 metres per day, leading scientists to revise the moving ice volume to 800,000 cubic metres. In early summer 2024, heavy June rain in Val Ferret set 220,000 cubic metres in rapid motion, and Italian geologists placed the glacier under "special surveillance".
