There is a world above the fog line, as we discover. Two hundred and fifty metres above sea level, we emerge into a landscape filled with colour. The sky is a cerulean blue. Like the inhabitants of Plato’s cave, we are stunned to learn of the existence of this brave new world. If we return to the world of fog the others will not believe us, and may kill us. We can see the fog lands stretching out beneath us, to the river valley, southwest to the capital, and far beyond. Best to stay put.
We hear gunfire from further up the cwm: men are hunting with dogs, which is against the law of the land. There is a woods, and the way is perilous, but we make it onto the upland pastures of Darren fach, the disused quarries of a deeper green than even the grasslands, the sheep dropping currants, the various fungi now at season’s end, among them the liberty cap, psilocybe semilanceata, the collection or possession of which is against the law of the land: but whose land? Three watchful horses graze where once there were two. Who is the third that always walks beside us? We sit by the cairn and eat our sandwiches, drink hot tea from a thermos. I wonder whether the farm that lies at the base of a perfect parallelogram, below Pen Gwyllt Meirch and surrounded by three fields — three adjacent parallelograms — was built there by design or by accident. Or whether the design — if indeed that is what it is — stretches far beyond that corner of the hillside to encompass all of this, and us.
Or whether that particular shade of russet, edging to ochre, or is it saffron — no colour chart could do it justice — can ever be replicated in a photograph or painting, any more than I, seated beneath the cairn, knife in hand, dropping apple peel for the luminous insects at my feet, might discern the vast and intricate pattern of spider webs that lattice the entire hillside and which glitter like a silvery counterpane under the oblique rays of the winter sun as it falls behind the bulk of Pen Allt Mawr.
Coming off the mountain, one of the horses, silhouetted against the mist — which has edged up the valley just a tad — eyes us with suspicion. The air is colder now. Retracing our steps down the forestry track, a pair of deer appear from our left at speed, leap across the path ahead of us, and vanish.
