"A million years ago, this was the site of an enormous catastrophe," explains Christian Koeberl, a geologist from Vienna University, Austria.
"We had a lush rainforest, filled with animals minding their own business, when a kilometre-sized rock came hurtling down from space, at enormous velocity, and crashed into the ground here.
"Within a few seconds, it opened up a gigantic hole in the ground which later filled with water and became the lake we see today," he told the BBC World Service's Discovery programme.



Drilling for Africa's climate history

The researchers traveled by increasingly smaller planes, Ski-doos and finally sleds dragged on foot to arrive at the Pingualuit Crater, located in the Parc National des Pingualuit in northern Quebec. The crater formed about 1.4 million years ago as the result of a meteorite impact, and today it hosts a lake about 267 meters deep. Its unique setting – the lake has no surface connection to other surrounding water bodies – makes it a prime candidate for the study of lake sediments.
