Another beautifully, stunning day in the Cairngorms. Kath, Matt and I headed back over the back to Hell's Lum today. Busy Coire an t-Sneachda and well trodden stepped path up the goat track. On the other side the sun was shinning bright and warm! Quite busy today, at least 2 teams in Deep-Cut Chimney and a team in Hell's Lum, numerous other teams also headed in as we started to climb. We climbed a combination route of starting on the ice of Brimstone Groove then the mixed finish to Towering Inferno. The ice was thick enough to climb, however the heat of the sun was melting the ice above! Lots of stuff falling off and ice screws were nearly melting out by the time we got to the belays! Very enjoyable day, maybe even got a little sun burn! Cairngorm summit, pt. 1141 and top of Fluted Buttress.
