This avalanche was on a North aspect at 555 metres. From the evidence of the footsteps to the left it looks like it was triggered and happened yesterday.
Several centimetres of snowfall arrived this morning before clearing at midday. There is newly drifted windslab affecting mainly South and East aspects which contain some very weak layers.
Picking a way down the Goat track in Coire an t Sneachda Cairngorm Plateau with Sneachda cornices visible on right
New snow accumulations of soft slab are present, deep in some places which gives some suspect slopes. generally the soft snow can be avoided at present, but the stronger winds with more snow will make the windslab accumulations much more significant.
'Steaming' up Aladdins Mirror Direct Coire an t Sneachda Good Climbing in the Corries - a very windy day with not much new snow to speak of - stayed pretty cold - great conditions for climbing.
Good placement on the ground ! In the colder temperatures the snowpack has frozen pretty hard - very slippy ! due to the drizzle of early morning providing a nice frozen glaze everywhere above 600 metres. Breakable crust in many places - but the climbing will certainly improve - for skiing off piste or touring !!!! difficulty in holding an edge in places, crampons felt great!
We have mild temperatures in the Cairngorms with the freezing level above the summits. Its not all doom and gloom though as it's still looking very wintry in the Cairngorms and the weather outlook is suggesting cooler temperatures for over the new year.
Looking down the Ciste Gully whilst braving the Strong South winds. Drifting is very heavy at higher altitudes. The terrain is still hard and icy on exposed slopes with accumulations of windslab in the more sheltered areas. Working in today's wild Conditions above the Ciste Gully on a North aspect at 790 metres.
Wind starting to arrive at Fiacaill Buttress Bad weather approaching from the South Wind increased in speed dramatically around midday with very strong SW winds at plateau level.
Coire an tt Sneachda slab cracking underfoot very easily - !! New windslab is very weak as it is forming onto buried surface hoar which is pretty evident when you travel around as it will crack and block away underfoot.
The new weather system of southerly winds which will be gale force form sunday evening will drift new slab onto the surface hoar in many areas, so be wary of any new slab , and have a great day working off the turkey !!
The best view once descended from the clag - Good skiing and climbing to be had, new snow will lie on a weak layer of surface hoar and will be unstable where it accumulates into windslab on East aspects.
Looking toward Carn Etchachan whilst heading down Coire Raibert Great conditions for both climbing in the corries with boiler plate snow-ice and ski touring on the plateau - but watch out for very hard snow ice hidden below powdery shallow snow.
The cloud cleared at long last and what a stunning day. A few centimetres of fresh snow fell last night which has left a blanket of snow over the hard icy layer....nice for ski touring.Views looking across the Plateau and into the Northern Corries. In the picture is the RAF sea king they came over to drop the stretcher off from yesterdays rescue. Here is a mixture of surface hoar and new snow.
Still very cold with snowpack weaknesses on many aspects. Facets are developing due to steep temperature gradients within the snowpack. This small cornice didn't
take much persuasion before it collapsed The views were not so great today
Some avalanche debris was noted just below Jacobs ladder on the right of this photo and below mess of potage below the crag apron. The snowpack very cold and weak on many aspects. Tap test revealed a weak faceted layer just above the old hard snow ice layer on a NW aspect at 1050m.
Clouds lifted around midday to reveal the crags in the Northern Corries. The approach slopes are mainly very firm and icy but there are a few patches of weakly bonded wind slab mainly in steep sheltered locations.
It's forecast to be another cold day tomorrow (minus 9 on the tops) so wrap up warm and have a fun day.
At the snow pit site on the South East side of Cairngorm - bitterly cold and windy !! The old snowpack has refrozen completely and is very hard, the new snow is building very rapidly in the strong winds and is pretty poorly bonded in itself, surface cracking when walking, indicating weak layers below. Layers of Graupel are the culprit. So the new snow is pretty weak wherever it is lying. The old snow is providing really good snow ice and good climbing conditions.
Snow is a bit easier to get through today - has become more crusted above around 700 metres, pretty pleasant but windy first thing - cooler temperatures have started to firm things up, looking promising for climbing with the expected colder temperatures.
Looking at Aladdins Buttress with two folk heading towards Aladdins Coulouir.
Hard walking getting to the corrie thigh deep in places with wet snow at lower levels - just moist above 700 m. Getting colder from tomorrow which will really improve the conditions both for climbing and snowpack stability. Some cornice collapse evidence at base of crags.
A very cold day with strong Southerly winds and heavy drifting, North facing slopes getting loaded with new snow, cross loading onto East and West slopes too. On a number of aspects windslab overlies very sugary unstable layers, surface cracks and slab releases occurred when descending the Fiacaill of Sneachda on West facing slopes. A wild day !!
Leaving the cairn at the top of the Fiachaill a Choire Chais Looking into Coire ant Sneachda
Crown walls of observed avalanche are just visible in the top left corner of picture. Avalanche released either yesterday or last night. Crown wall 1m deep in places and 100m across has travelled 350 metres with enough debris to bury a car (size 3 avalanche) NW aspect 1100m.
A respite in the storm gave us some visibility for a short while - closing in again later with heavyy snowfall. Snowpack remains weak on most aspects.
The only view ! Looking across Loch Morlich to Cairngorm. Deep snow everywhere above 500 metres, hard trail breaking - really poor visibility today -
I expected more scouring of the snow from NW aspects, but this was not the case. Generally the snowpack feels spooky and unstable especially by not being able to see what is above and being unable to see any angles or definition in the flat light.
Looking West from Cairngorm toward Northern Corries
Conditions shaping up to be very good for walking and climbing - the snow although still fairly soft is developing a crust which increasingly holds your weight as you ascend in altitude. Colder temperatures will continue to improve the situation.
Looking into Coire an t Sneachda fro windy col Looking N toward Glenmore from the top of the Goat Track
Winter has arrived and it looks as though will be cold from this weekend and into next week at least.
Today the snow has been pretty soft and is generally moist, after much avalanche activity in the week the snowpack has settled in the warmer temperatures and become much firmer with good climbing conditions in prospect.
