British Botanists conducting a Summer survey of Scotland’s tallest mountain, Ben Nevis, have been stunned to find evidence of recently formed multi-year ice fields, areas of compacted snow, some of which weigh hundreds of tons.
According to the BBC;
“Hazards common in arctic and alpine areas but described as “extremely unusual” in the UK during the summer have been 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.

This is how ice ages start – a buildup of snow which does not melt in the Summer, which leads to a positive feedback loop, as the growing ice sheet reflects more and more sunlight back into space.
