Glaciers starting to form in Scotland - from the Beeb:
Glacier-like hazards found on Ben Nevis
A team of climbers and scientists investigating the mountain's North Face said snowfields remained in many gullies and upper scree slopes.
On these fields, they have come across compacted, dense, ice hard snow call neve.
Neve is the first stage in the formation of glaciers, the team said.
The team has also encountered sheets of snow weighing hundreds of tonnes and tunnels and fissures known as bergschrunds.
The large, deep cracks in the ice are found at the top of glaciers.

Lead survey botanist, Ian Strachan, said: "Many of the rare arctic-alpine species we are searching for are relics from soon after the last ice age.
"Ben Nevis and a few other peaks in the Scottish Highlands provide the most southerly refuge for some of these species which can only survive due to the altitude and presence of semi-permanent snow fields."
And the next ice age is scheduled to start in 3... 2...
