Bridge Over the Navisence

The La Navisence river is fed by the waters of the Zinal glacier. This also gives it its greenish color, because the water from the glacier also causes larger quantities of rock particles to flow into the river, which primarily reflect the green part of the light and absorb the remaining wavelengths more strongly. Towards the bottom of the valley, the river has carved a deeper gorge, bordered on both sides by shimmering green rocks. These are mainly highly metamorphic chlorite and amphibolite schists.

The bridge was destroyed in the flood in June 2024. A wooden bridge was built a little way upstream. That means about a half hour detour, but you can cross the river dry-footed and the area is just great, so the few extra steps don't matter.
