Overview
- An Italy–France team led by Fondazione Montagna di Courmayeur with Université Savoie Mont‑Blanc measured the summit at 4,807.3 meters.
- Drones, remote sensing and ground‑penetrating radar established a reproducible baseline or “state zero” for future comparisons.
- Scientists detected about 20–25 meters of ice beneath the summit surface, with underlying rock around 4,786 meters.
- Preliminary data suggest a gradual recent lowering of the peak’s elevation, a hypothesis researchers say must be confirmed by repeat surveys.
- The effort forms part of the International Year of Glacier Conservation and targets long‑term tracking of high‑altitude glacier change.
