This video clip shows a very close call for those aboard a small boat off the coast of Greenland. The video's owner says:
A tourist from Australia came to my uncle and asked if she could get a ride to the glacier just north of Ilulissat, Greenland, so he asked me if I wanted to be his translator. I am from another town where glaciers are fairytales, I was as much of a tourist as the Australian tourist, so I decided to join the crew.
The beautiful scenery was amazing, but the nature doesn't care about anyone. That day almost became our last day.
Here's how it went down. I highly recommend watching the video in full-screen mode.
Near-misses don't come much closer than that . . .
