Postcard Zig-Zag-Schlüff, Luxembourg's Little Switzerland, walker in rock cleft

Black-and-white postcard of the Zig-Zag-Schlüff in Luxembourg's Little Switzerland, published by Kunstverlag P.C. Schoren, Luxembourg, as number 41 of the Serie Müllertal. The composition looks down from above into the rock cleft, where a stone staircase descends in zigzag between mossy sandstone walls. In the middle of the path stands a walker wearing a bowler hat, with a coat or blanket over the shoulder, holding a walking stick raised aloft. In the background the cleft opens toward a lighter passage surrounded by young trees. The printed caption "Petite Suisse luxembourgeoise - Zig-Zag-Schlüff" appears at the bottom. The card is in good condition.

The Zig-Zag-Schlüff, in Luxembourgish Zigzagschlëff, takes its name from the zigzagging course of the stone staircase through the rock cleft. The gorge forms part of an extensive labyrinth of rock clefts around Berdorf that also includes the neighbouring Siweschlëff, Werschrummschlëff and Binzeltschlëff. The Luxembourgish suffix "-schlëff" denotes a cleft or narrow passage, formed where sandstone towers slid down a slippery marl layer and detached themselves from the rock walls. The cool, humid microclimate inside the crevices shelters rare mosses and ferns. The region has belonged to the UNESCO Global Geopark Mëllerdall since 2015.
