Great stats, where did you get them? Higher parts of N Pennines are significantly colder than those sites you have mentioned. Upper Weardale/Teesdale area will have been nearer 110/120 perhaps. I have a paper by S.D Burt (Snowfall in Britain during the winter of 1978/79) the only figures are 166 Days for Great Dun Fell, 202 Days Cairngorm, 200 Aonach Mor. Mark I know Gordon Manley thought that was snowiest winter at higher levels but that was written pre 78/79. Spring 79 was cold thats what extended the season at higher levels. Dont know what 1950/51 spring was like? Mark
