I went to Snowdonia to photograph the effects of the cold weather gripping the country. After several days of sub-zero temperatures, Llyn Cwmffynnon, a glacial lake between Glyder Fawr and Moel Berfedd, is under ice. Intriguing patterns in the ice suggest that the lake froze while wind was rippling the water surface. Although Glyder Fawr was hidden in cloud, I was able to include Moel Berfedd in the background. I spent a while fine-tuning my position to make the most of the foreground rocks so when lovely pink tones spread across the sky at sunset, my composition was ready to go.
