The story of Jack Carne is testament to that. Jack and his two best friends had travelled a few hours from their hometown of Barnsley to reach the mountains of Eryri, also known as Snowdonia, in north Wales. Inspired, after the Covid-19 lockdowns, by the freedom the mountains offered them, the trio in their 20s had been out hiking at every possible opportunity. They were committed, fit and experienced – but on this occasion, just “10 metres from the top” of Glyder Fawr, a peak thousands of feet up, everything went wrong.
