Winter of 1947
Thousands of people were cut off for days by snowdrifts up to seven metres deep during the winter of 1947, which saw exceptional snowfall. Supplies had to be flown in by helicopter to many villages, and the armed forces were called in to help clear roads and railways.
Between January and March that year, snow fell every day somewhere in the country for 55 days straight. Much of this settled because temperatures stayed very low, just above freezing most days.
