#13 — Seventy four snow patches survive until winter 2015/2016

The new snow that’s fallen over the Highlands of Scotland in the last week or so has proved to be ‘lasting’. The text below is taken from last year’s entry, and describes what this term means:

Some people have asked me what ‘lasting’ snow is, and how do I know it’s come. Put simply, ‘lasting’ snow is that which falls and subsequently fails to melt. So, for example, if an old patch of snow gets even a sprinkling of new stuff on the 12th October, upon which it sits for a week and is then completely buried by a blizzard on the 19th October, the date of ‘lasting’ snow is computed as the 12th. This is the way that Adam Watson has calculated it in his decades of snow-patch monitoring in the Cairngorms and other places, and to me it’s the most logical method.

2015’s survivals. In total, 74 (seventy four) patches of snow survived to winter, and they are listed below (ordered by: patch numbers, hill, location on hill). The underlined text has a link to an Ordnance Survey map of the location snow persisted.
