OK, I give up.. the weather keeps changing, but the message is the same...please remember your basic safety precautions.. map, compass, whistle, survival bag, extra clothes, torch and brain... all the information for a safe day out is readily available.. weather forecasts and sunset times. It's approximately 3 degress C cooler every 1000' climbed, and much colder when you're forced to be imobile.. and there's still a lot of snow and ice around...
