Monte Toc, Mountain summit in Province of Belluno, Italy
Monte Toc is a mountain in the Eastern Dolomites in the Province of Belluno, rising to 1921 meters with steep slopes and thick forest cover. Its geological structure combines limestone and clay layers that shape the terrain.
The mountain gained international attention on October 9, 1963, when a massive landslide from its slopes caused a catastrophic flood at the Vajont Dam. This event exposed the mountain's geological fragility to the world.
Local people call it the Walking Mountain because its name comes from a Friulian word meaning unstable or crumbling, reflecting how they understand the restless nature of this place.
Multiple hiking trails reach the summit and proper mountaineering gear is needed while following local safety guidelines. The terrain demands experience and fitness due to steep grades and areas that may be unstable.
The slopes are unusually prone to ground movement, meaning the mountain has visibly changed over the decades. Visitors often overlook that they are exploring a place whose surface continues to shift and evolve.
