Exoplanet... Pingualuit Crater, located on Quebec's Ungava Peninsula in Canada, is a nearly perfect circular formation created by a meteor impact 1.4 million years ago, measuring 3.44 km in diameter. It encloses Lake Pingualuk, one of North America's deepest lakes at 267 meters, with exceptionally clear, low-salinity water (<3 ppm) fed solely by rain and snow, lacking inlets or outflows.This pristine site served as a WWII navigation landmark for pilots and is now protected within Pingualuit National Park, established in 2004. It offers a glimpse into Earth's ancient history, blending scientific intrigue with stunning natural beauty.
