This is not a natural pond in the forest. Look closely and you will see the edges are of concrete. There are many of these ponds in the forest. Rainfall in the forests of the Vaucluse mountains in France is scarce, so water is hauled up the mountain to fill these ponds regularly otherwise the wild hogs and deer would die of thirst. Who are these good people who bring the water? Hunters of course – if the animals died, they would have nothing to shoot.
