Scotland had a glacier up to 1700s

Britain's last masses of slow-moving ice and snow were understood to have melted 11,500 years ago.
Dr Kirkbride studied the formation of corries in the Cairngorms.
A corrie is a basin-shaped feature created by glaciations in the mountains.

Glacier in Patagonia “present climate warming means there is little chance of a return of glacier ice to the Highlands for the foreseeable future”

Using a technique called cosmogenic 10Be dating, Dr Kirkbride showed that a small glacier in a Cairngorms corrie piled up granite boulders to form moraine ridges within the past few centuries, during the period of cool climate known as the Little Ice Age.


Dundee University said scientists had speculated that glaciers may have re-formed in the Highlands around the time of this Little Ice Age but hard evidence has proved to be elusive.
Dr Kirkbride teamed up with Dr Jez Everest at the British Geological Survey in Edinburgh, and the Cosmogenic Isotope Analysis Facility at the Scottish Universities Environmental Reactor Centre in East Kilbride, to carry out the research.
