The glacier looms over the city like the "Game of Thrones" series' immense ice Wall towers over the stronghold Castle Black.
Kieran Duncan, a lecturer in communication design at the University of Dundee in Scotland, created the video with Max Van Wyk de Vries, a glaciologist at the University of Minnesota.They included the 571-foot-tall (174 meters) Dundee Law hill, a local Dundee landmark about as tall as the Washington Monument (555 feet, or 169 m tall), to illustrate the glacier's size. .
"Part of the film shows what a 1 km ice sheet would have looked like on top of the [Dundee] Law, and I remember my mind being blown when Max first told me about that," Duncan said in a statement."You hear numbers like that, but it's only when you see what that would have looked like in relation to something like the Law, which towers above the city, that you really start to conceive of just how massive this glacier was.".
As Earth warmed up again about 15,000 years ago, the glaciers retreated and carved out features in the landscape, such as the Dundee Law, according to the statement. .
The 3-minute film uses animated visualization techniques, filmed footage and time-lapse video to bring the ancient glacier to life over Dundee.
