Mont Blanc measured at 4,807.47 m in latest survey

The Haute‑Savoie Chamber of Surveyors announced that the summit of Mont Blanc stands at 4,807.47 metres, a rise of roughly 1.88 metres compared with the figure recorded in 2023. Jean des Garets noted that the mountain’s summit is constantly moving and that a single measurement offers limited insight. The new figures were released alongside the latest set of numbers that have been published each year for the past quarter‑century. The updated measurement differs slightly from the altitude taught in schools and from the previous release in 2023.
