Very cold and sunny with lows of -17C to -20C in the glen; however it felt pleasantly warm in the sunshine at -5C!

Weak layers persist at depth within the snowpack, but these are mostly protected and bridged by hard windslab.
Skiers and climbers can trigger this layer where the hard slab becomes thinner especially at the top of convexities.
The snowpack surface also has a widespread cover of flat smooth crystals called “surface hoar” down to glen levels.  These create a smooth sliding surface when buried by new windslab.
See Northern Cairngorms avalanche report for more details.

An arctic landscape.

Loose grains within the snowpack creating weaknesses which are bridged by hard windslab.

Interesting crystals have formed on top of a small exposed bog at 650m.
