We've all heard that the ice is melting in Canada's North, but it's unusual to see it break down right before your eyes.

In this week's video, Wanda Stead and her husband were recording a spectacular iceberg arch located off the Newfoundland coast when the iceberg suddenly collapsed, causing large waves to roll towards Stead's boat.

The video's an important reminder that there are risks to tourists in viewing these amazing natural structures and it's important not to get too close.
