Секреты снежной мантии
I think that in addition to study the depth of snow cover, we can try to collect folk omens associated with snow cover and discuss them.
For example, I was interested in such a sign "If zaporoshen October snow, spring snow for a long time will not leave the field." It was in October this year in Moscow was unusually snowy. On the other hand I am sure that there are regions where snow falls in September. Possible for them this sign does not work.
And what signs do you know?
