Pingualuit Crater Mystery solved

1.3 Million years ago a chunk of rock flying through space hit Northern Quebec with the force of 8,500 Hiroshima atomic bombs, Since then things have cooled down a bit and the crater has filled with water, there is no water flowing in or out of this crater, it has been catching rain for the last 1.3 million years. Along with the rain water it has also trapped pollen, from plants in the region, and dust from the atmosphere. These sediments have been keeping a record of our climate for at least 120000 years.
An international team led by Laval University in Quebec City has recently returned from the Pingualuit Crater and hopes to unlock 120,000 years worth of secrets about climate change. For more information on the research going on at this crater have a look at this article, recently published in the globe and mail.
