Strong winds with spindrift
15th December 2019
Some snowfall arrived during the night. Â Currently the strong Westerly winds winds have created a lot of drifting snow over the tops (40 gusting 60 mph). Â The breakable crust is still widespread. Â Soft accumulations of windslab have developed in lee areas. Â The plateau has a thin cover of snow and rime ice with patches of old firm snow, and deeper drifts in some areas.
Minus 5C on the summit of Cairngorm with drifting snow.

With your pit that failed at 20cm was it a compression test, extended column test etc, and how easy did it fail? compression test (CPV -CPH) or if an ECT was used was it propagating or not very reactive (ECTPV – ECTN)?
