Here's a clue. I took it on 11th February (last week).

Here's another clue: It's the middle of winter.

And another: This mountain - Yr Wyddfa or Snowdon - is the highest in England and Wales.

But where's its winter snow covering? Predictions made a year ago suggested no snow for Snowdon in 13 years. There has been a little snow from time to time this winter but not, as I write, for weeks. Need I say more?
