Not far from Haytor on Dartmoor, on the side of a low ridge, is a windswept tree that shelters besides a small Tor and amongst rocks. This day in February 2019 had been cold and mostly sunny. Around sunset the clouds retreated leaving a bank of thin cloud on the horizon behind which the sun dipped. As it did so, and for a few minutes, the light turned casting an orange glow across the rocks and tree.
