Nanztal
The Nanztal is a now uninhabited, small side valley in the German-speaking part of the canton of Valais in Switzerland .
location
The Nanztal runs from south to north and lies in the area of the municipalities Visperterminen and Brig-Glis between the Vispertal and the Simplon Pass . The valley begins at the Gamsa glacier below the Fletschhorn and is traversed by the Gamsa mountain stream, which flows into the Rhone at Gamsen . There is no publicly accessible road into the Nanztal - except for an alpine path from Visperterminen that can only be used with a special permit. The road from Gamsen above the "Gamsuch" (Gamsaschlucht) to the Nanztal, which was built in World War II, is interrupted today and can only be used by pedestrians and cyclists. In the rear part is the small Blausee on the western slope of the valley.
Development
The valley is only used gently for tourism. National hiking route 6 from Wanderland Schweiz , the so-called Alpine Passes Trail , leads from Chur to Saint-Gingolph on the stage from the Simplon Pass over the Bistine Pass through the Nanztal and on over the Gibidumpass to Gspon . The hiking time for this section is approx. 8½ hours. Another hiking trail leads from the Gibidumpass along the Heido Suone and then on the other side of the valley as a continuous high path to the Bistinepass. Another high-altitude trail leads from Visperterminen below the Gibidum over the Wissy Flüe into the Gamsasuch and then into the interior of the Nanztal or over Gamsen to Brig .
history
The Nanztal and the Suone Heido were first mentioned in a document in 1305. The name "Heido" used indicates that even then it was no longer known when the first aqueduct from the Nanztal was built (today in places still visible from the opposite side of the valley below the current course). The "Heido" initially carried water from the furthest Nanztal around the Gibidumpass to the dry pastures of Visperterminen. Today the northernmost section is abandoned. Today the Gibidumsee is fed as a compensation basin by the Heido through a tunnel under the Gibidumpass.
Further down the valley, first on the right side of the valley in front of the Gamsuch and then after this on the right side of the valley, there are two more suonen: - The extraordinarily bold "Rohrbacheri", which is laid out in the steep rock of the Gamsuch and supplies the hamlet of the same name, Rohrbach above Eyholz and - the short "Gliseri" branching off from the Gamsa above the explosives factory.
Since 1916, water has been conducted directly from the Gamsa to Visperterminen through a 2.65 km long water tunnel under the Gibidum. The recording takes place at the grassy Nidristi Alp . Another part of the water is fed through another tunnel to the remote Ackersand 1 power station near Stalden in the Mattertal .
It can be historically proven that some of the 3,000 Lombards who crossed the Simplon Pass to support Charles the Bold of Burgundy in Murten against the Confederates wanted to penetrate through the Nanztal and were wiped out by the Vispern here.
