It’s amazing. it’s like watching a continent fall away. Watch all the way to the end to get a size reference of what you have witnessed.
“CHASING ICE” captures largest glacier calving ever filmed - OFFICIAL VIDEO
Incredible footage, sadly I guess we’ll be seeing a lot more of this with global temperatures on the rise.
Interesting video. … I also found it interesting when linked-to in March. 
Apparently that was filmed in 2008?
Since we’re always hearing about larger pieces (state-sized in some cases), I assume this is just the largest caught on film, a factor of how difficult it is to film these events.
