Another wonderfully atmospheric day at Garbh Choire Mòr to check whether the last patch of snow in Scotland survived the recent deluges.pic.twitter.com/VHEo4DDJNt — Iain Cameron (@theiaincameron) October 2, 2022Just six days ago he had made the climb to check on the patch and described it as "hanging on for dear life."Mr Cameron, based in Stirling, has been studying snow patches in Scotland for 25 years and is author of the book The Vanishing Ice, which he describes as a "lament" to snow and ice that lingers high in Scotland's hills.Separately from Mr Cameron's research, a report commissioned by Cairngorms National Park Authority and published in July 2020 said declining snow cover, and fewer days when it snowed had been observed on Cairngorm mountain since the winter of 1983-84.The Sphinx lies in Garbh Choire Mor, a hollow known as a corrie formed by ice or a glacier during the last ice age."
