After the thaw….
18th March 2026
Today was dry, clear and quite calm it has remained mild with summit temperature (1100 metres) of plus 2.5 degrees celsius. Winds were light from a South-Westerly direction. Some photos from today show the various remaining snow amounts.
Looking from Meall a’ Bhuiridh across to Creise and then on to Stob Dearg with the Mamores hills in the distance.
Meall a’ Bhuiridh with good evidence of Snowpack sink lines, often referred to as parallel drainage lines or sun cups, appear on the surface of the snow after heavy thaw conditions or rain-on-snow events due to the concentrated flow of meltwater. These lines, which can form within 36 hours of a thaw, signify that water is moving quickly through the snowpack, forming channels that create visible depressions or “sink lines”.
