The shadowy internal world of the snowpack
Sometimes a cornice will creep or slump rather than completely collapse. This usually happens when the temperature is close to freezing and the snow quite ductile. At lower temperatures any failure tends to be more brittle, which is more likely to lead to complete collapse. This creeping and deformation sometimes opens up a large cracks a little way back from the edge. In Coire Dubh on Aonach Mor, about a 30 metre long section of cornice slumped earlier this week, producing a crack wide enough to climb into at various points. A few days of consolidation, it felt safe enough to crawl into this for a wee peak at the strange, blue, internal world on the Scottish snowpack

Sub-optimal weather on the Ben

Carn Dearg buttress. Although the CIC hut cascade is complete, it is reported to be hollow and wet at the base.

Back to Beag
A quick stomp round the top of the snow pit, and the top 10cm to 15cm of the snowpack sheared off quite easily.
Looking South to Aonach Beag.
Some pretty substantial cornices exist. Although you can't see it in this picture, some large cracks exist about 5 feet back from the left hand end of this cornice.
It was back to Aonach Beag for me today. Most of the way over Aoanch Mor with in thick cloud, but it cleared up for a brief period when I got to when I got to the col. The snow down to the col had a slight wind crust on it, making for some quite tricky skiing. At higher level there has been a fair bit of fresh snow over the past few days. It was quite mild when this started to fall, and then turned colder, so the deeper layers of this fresh snow are quite well bonded. However, the top layers are not so well bonded (see top photo).

Aonach Beag
Climber belaying on Coire an Lochan. Conditions were reported to be quite verglassed.

Aonach Beag.
Despite a slightly threatening sky it was quite a pleasant day on the hill. I took a wander over to Aonach Beag. The snow is generally pretty firm with crampons being necessary on all but the gentlest of slopes. Although isolated there are a few wee pockets of slab about.
