Andrew Cotter and Iain Cameron first met on twitter, though neither will admit who made the first move. They've been walking together since 2016 and are often looking for snow. Iain researches snow patches across the Highlands and Andrew seems to enjoy coming along for the ride. On a marvellous early sunlit morning they climb the Grey Corries with producer Miles Warde and try to work out how much snow will survive the summer heat.
Iain Cameron is the author of The Vanishing Ice. He's been drawn to the white patches of the Scottish Highlands since 1983. Andrew Cotter is a sports reporter and the author of several books about his dogs, Mabel and Olive.
