Iceberg #2

INCREDIBLE COLLAPSE TRIGGERED BY GLACIER CALVING | South America, Chile

Update:

Curious how the bottom of the berg flips up. I has expecting it to topple forward, but then I wasn't expecting it to be a one thousand feet tall either. Nine tenths of an iceberg is underwater, so if the glacier cliff face is one hundred feet tall, then the ice must go down for another 900 feet below the water line.

Paraphrased from the YouTube blurb:

A large chunk of the Grey Glacier's ice-sheet breaks off and flips over in Southern Patagonia, Chile. The ice-sheet of the Grey Glacier is part of the 'Southern Patagonian Ice Field', the world's 2nd largest contiguous extrapolar ice field and the largest freshwater reservoir in South America.

The glacier wall collapses during the summer when large icebergs – often up to 100 feet in height – are breaking off the glacier and collapsing into the water of 'Lago Grey'. The waves created by such glacier calving events often splash dozens of yards through the air. The glacier itself is about 3.7 miles wide and has an average height over 100 feet above the surface of the water.

Back in December 2024, which is 38 years after it broke off of Antarctica, it covered 1,400 square miles. Now it's only half that size and they aren't expecting it to last much longer.

Has anyone been there? Google knows:

When the iceberg calved from Antarctica's Filchner-Ronne Ice Shelf in 1986, it broke off with a Soviet research station, Druzhnaya 1, still on it.
