From somewhere out in the vast whiteness of the blizzard we hear a cry for help. Instinctively the three of us turn and head across the mountainside. We find two men and a woman, huddled together in the snow, unable to descend the steep icy slope between them and safety.

The woman asks if we are experienced in conditions like this. My friends and I have tackled a few winter hills in the Lake District and bumbled up easy rock climbs, but we have never been in a full Scottish winter snowstorm. I laugh and assure her that this is nothing to mountaineers like us.

Soon our hills will be empty and one day the last hillwalker will disappear over the horizon. In the 21st century we are losing our connection with the wild, a connection that may never be regained.
