“Goyas” - natural-looking artificial ponds - are scattered across the Grand Crêt d’Eau mountain pastures. In spring, when the snow melts, these goyas fill with water. A myriad of alpine newt tadpoles can be seen wriggling here in the morning sun.
The quick absorption of water by the karstic sub-soil and the lack of sources on summits led men to create these watertight reserves for livestock (excerpt from the booklet: “Au fil de l’alpage” or “Through the alpine pasture”).
