context_page_description: The Pingualuit Crater, formerly called the "Chubb Crater" and later the "New Quebec Crater", is a young impact crater, by geological standards, located on the Ungava Peninsula, in the administrative region of Nord-du-Québec, in Quebec, Canada. It is 3.44 km in diameter, and is estimated to be 1.4 ± 0.1 million years old. The crater and the surrounding area are now part of Pingualuit National Park. The only species of fish in the crater lake is the Arctic char.
context_section_description: Professor Reinhard Pienitz of Laval University led a 2007 expedition to the crater which extracted sediment cores from the bottom of the lake which were filled with fossil pollen, algae, and insect larvae. It was hoped that these finds would yield information about climate change dating back to the last interglacial period 120,000 years ago. Preliminary results show that the upper 8.5 m sediment core contains records of two interglacial periods.
