(Above) Looking towards Puist Coire Ardair at 1071m – on the right. Drifting all day above 850m. Natural dry slab avalanche activity on steep N to E aspects this morning.
(Above) Sron a Ghoire’s northern flank has been rippled with drifted snow and has cross loaded minor terrain features from opposite directions. Easterly winds earlier this week (blowing from the left) and more recently by Westerlies from the right. Note the re-entrant in the middle of the shot with its small cornice line, and drifting snow from the opposite direction. Another wind shift expected tomorrow with winds from the East again.
(Above) Pinnacle Buttress and Raeburn’s Gully in upper Coire Ardair. Recent avalanche crownwall and debris present in the gully this morning.
(Above) Coire Chriochairein’s SW ridge. Crownwalls and dry slab avalanche debris also present here, although the shade obscures the detail.
(Above) The broad gully in Coire Chriochairein was also carrying recent avalanche debris. A steep East aspect here.
(Above) The sun did come out at times and induced a little rollerball activity on S and SE aspects below about 750m. Bottom of shot. The thin soft surface snow lost cohesion due to solar warming. The deeper deposits of snow below this altitude are showing signs of consolidation.
(Above) Sron a Ghoire’s steep E and SE face: drifting at higher altitudes and sun-induced rollerball activity below 750m. It really must be Spring!
(Above) Looking towards the Post Face of Coire Ardair. The photo perfectly illustrates the somewhat contradictory weather we had today.
