In the village of Melness, a frayed twist of bungalows and old stone buildings on Scotland’s desolate northern shore, April is a month of new beginnings, when the dark and strung-out Highland winter finally unfurls into a tentative spring, and pregnant ewes balloon like airships in the wind-swept hills. As the 2015 lambing season neared its start, the villagers began the usual preparation of their small plots of rented land, called crofts, for farm and pasture. Behind the crofts and croft houses was the bog: an immense, bronze-hued ocean of deep peat, stretching into the horizon.
