(Above) Low level mist in Kingussie this morning but very much brighter further west on the commute to my place of “work” (….am I allowed to call it that?) Frosted up trees lit by low sunlight on the A86 near Creag Dubh crag. Just too good a photographic opportunity to pass up. Utterly gorgeous.
Really cold air temperatures today but sufficient radiant heat energy from the bright sun to loosen the soft unconsolidated snow surface. Radiant heat not always directly related to air temperature. Really easy to feel the warmth of the sun on your face but bitterly cold in the shade, especially at altitude.
(Above) Coire nan Gall photographed from the A86. Two slab avalanches triggered by direct solar radiation; one in a gully, the other on a steep ramp at 850m. A very steep East aspect. The debris from the avalanche on the ramp was split by the rocky outcrop before it came to a halt in the runout zone.
(Above) The long ridge of Creag na Cailliche which leads to the summit of Creag Meagaidh itself. (The Moy Corrie is down hill to the right.) Drifting snow at 900m! Bit a slight melt event due to sunlight at 850m, but cold enough a little higher for snow to be scoured from the surface and transported on to lee slopes. Bonkers!
(Above) Looking towards Aonach Beag (Ben Alder) viewed from Meall Coire Choile Rais. Plenty of wind transported snow on the move there. The Easterly wind picked up during the day and is actively stripping and re-depositing snow onto lee slopes, mainly West-facing ones.
Judging by the weather forecast we’ll be seeing more wind transport tomorrow.
