Dry and Cool on the Tops

Good dry conditions underfoot but misty and generally poor visibility on the tops with a brisk wind. Slivers of snow remain but these are largely avoidable, sometimes they bar descent and the snow can be pretty firm, here an ice axe and crampons would be gratefully used !

Looking down the SE side of Cairngorm towards Glen Avon, still enough snow  here for a ski run if your keen and willing to make the effort



Carn Etchachan and the Shelter Stone are beginning to look quite dry.

Ice smears forming on rock slabs

Looking up into Fiacaill Couloir
Cold temperatures today,  smears of ice are beginning to form.  

Coire an t-Sneachda.  A few teams were climbing fingers ridge.

Patches of snow mainly on E aspects.  Some accumulations are a few metres in depth at plateau level.

Very Spring like !

Mild and windy

Although its mild the remaining snowpack is quite firm

Mild with drizzle

NE facing slope at Ciste Mhearad
Although the snowpack is limited, greatest depths are on NE to SE aspects above 1000m with over 4 metres in places.

Wet patches of windslab from the previous days snowfall and drifting are visible on the old snowpack.

Vicious Wintry Squalls

Vicious squalls at summit levels provide a stark reminder of how rapidly winter conditions can arrive in moments.
Not a great deal of new snow but the heavy showers keep building it up - the old snowpack is bullet hard.

Cold and Clear with a Snow Dusting

Coire Lochain

Graupel grains which currently are on the  surface were originally  crystals that circulated in the clouds and have become more and more rimed, eventually falling as these pellet like grains.  They often produce weak layers

Cooler but with Rain on the tops

looking into Coire Lochain

Glide cracks in Coire Raibert


Glide cracks are tension failures in the snowpack created as the force of gravity downhill stresses the slope  and causes failure at a weak-point in the slope, in this instance at the convexity.  We are witnessing a very slow motion avalanche, however the snowpack may disappear before the slope fails and moves though !
In terms of avalanche hazard, we are mostly concerned with the triggering possibility due to our activity on a slope causing a layer to fail, which would be most unlikely here. It is very difficult to predict an avalanche in this situation, in much the same way as trying to predict an ice cliff collapse on a glacier, you never really know. However, I would not  recommend pitching a tent at its base !
