Temperature cycles and crusts

21st February 2022

Today was a nice dry and pleasant day with light winds. The recent temperature fluctuations have given rise to rime ice and a melt freeze crust, but only at higher elevations above around 900metres. Below this it has not really been cold enough over the past 48hrs.

Below the melt freeze crust at high elevations there are some weaknesses within the old snowpack, but these are being bridged by the crust at the moment.

Colder temperatures at altitude are leading to rime ice and an icy melt freeze crust.

Looking South from Aonach Mor to Carn Mor Dearg.

Looking down easy gully. There was evidence of an avalanche from the gully, most likely from last Saturday night / evening during the pronounced temperature increase that happened that night.

Looking across to the Southern crags of Coire an Lochan.
