Lac du Nino sits at 1,700 metres in the Rotondo Massif, Corsica. When the glaciers retreated at the end of the last Ice Age, they left behind a hollow in the granite. Water filled it. Over thousands of years, the lake slowly silted up from the edges inward, building layer upon layer of peat. What surrounds it today is something else entirely: the pozzines. The word comes from the Corsican for small wells. These are flat, waterlogged meadows. Acidic, soft underfoot, laced with a network of small holes and narrow channels. The channels are cut by snowmelt working through peat. The holes fill in spring and dry out by late summer. Horses and cows graze the plateau and compact the ground where they drink, deepening the pattern over generations.
