Returning to Lochnagar today it was very obvious that a significant thaw had taken place in the previous 24 hours: Water is now running down the line of Parallel B and conditions in Raeburn’s Gully have thinned out overnight. Once again, no rock fall was observed or heard but ice collapse was observed at close quarters. The remaining sections of overhanging/undercut snow are still in place around the rim of the corrie but with air temperatures of 10 degrees centigrade recorded at The Cairnwell (930m) this afternoon we wonder for how long…. Its forecast to be slightly cooler tomorrow but it will be a sunny day with South facing aspects receiving a lot of solar warming.
Low cloud today so not many good photo opportunities…

The ice on Lochnagar is now really starting to break up in the warmer conditions.

 

Low cloud today. No rockfall seen but ice collapse was observed at close quarters. Softer snow conditions.

 

Beinn a’Bhuird holding onto large areas of snow but a great deal of cover has been lost in the past 24 hour period.
