It was another very cold day with moderate Easterly winds. Lots of sunshine made things feel a bit warmer than the thermometer was suggesting. Some pictures below showing the effects of the recent very strong winds on the snow.

Fragile cornices above a gully on a South-East aspect at around 450 metres.

Large volumes of snow deposited in a sheltered location and then partially eroded by strong winds at around 450 metres.

Wind erosion. The snowpack on this East aspect has an icy crust on it with softer snow below. On most of the slope the icy crust has resisted the attempts of the very strong winds over the last week to erode it but once the wind has removed a small part of the crust it can then remove the softer snow below with the unsupported crust then more easily eroded by the wind. These strange shapes in the snow, which look a bit like small slab avalanches but with no debris, are what’s left.

Slioch from the South-East.
