A massive iceberg named A-68A is on a long journey through the seas near Antarctica. Though largely empty, those waters do host some islands, most notably South Georgia Island. In recent weeks satellite images showed the iceberg heading right for South Georgia.

That upcoming collision could have devastating consequences for wildlife that congregates on the island. But now, it looks like the collision might not happen.

Back in July 2017, satellites watched as an enormous iceberg broke free from Antarctica’s Larsen C ice shelf on the Antarctic Peninsula. The trillion-ton behemoth has been drifting for over three years now. While it stayed close to its parent ice shelf for the first couple of years, it’s now heading directly for a collision with South Georgia Island.

It could be a slow-motion collision, but a collision nonetheless. If it does collide with the island and its shallow sea-floor, it won’t be the first iceberg to do so. And if the first one was any indication, wildlife could suffer.
