As declared by UNESCO World Heritage Site, Quebec A friendly Canadian city, with unwavering security, that is Calling to explore on foot. Its cobbled streets are reminiscent of other times and customs. As a city It holds some unique secrets, such as the one-walled city in northern Mexico. But it’s not just the dazzling interest that defines it. The mystery of moving beauty lies in its proximity.

A meteorite about 400 feet in diameter It suddenly fell into the atmosphere. Traveling at a speed of 20 miles per second, it collided with the Earth, sending boulders in all directions and carving a hole in the surface of the planet. The Pingualuit trench, Located inside the tundra of the peninsula உங்கவா In the north of Quebec, it got its name A perfect circular crater formed by a meteorite fall that occurred on Earth a million years ago. A Wonderful eye The earth is visible when you fly from it.

A Toronto newspaper reporter saw it A 1950 trip And broadcast it for the first time. Called him “Eighth Wonder of the World”. The Kangxujuwok InuitThe nearest town, which was already known, describes it as a ditch “Nunavingmi Bikminar”, which means “the place where one is revived”. Currently, this is the main attraction The province’s new national park, the Park National des Pingloid, was created in 2007.

Most of the lakes in the northern perimeter are glacier-shaped and, due to their sedimentary glacial erosion, allow only predictions that last until several thousand years ago.

The edges of the pingualuit rise 160 meters and form a lake insideDue to snowfall and rain, it has become even 400 meters depth. Pingualuit, with More than 3 km in diameter, no open entrances or exits, So only stagnant rainwater is lost through evaporation. In addition to being One of the deepest lakes in North America, with a view of more than 35 meters, it is considered one of the most open and clear lakes in the world.

This vast bed was first identified by the crew of a US Air Force aircraft. In June 1943, But His pictures were only published in 1950. Prior to that, the crater was known only to local Inuit people He named it Nunavik’s Crystal EyeDue to its thin and crystalline water purity.

The location offers a unique opportunity Read the dynamics of the Earth’s climate. It is possible not only during the post-glacial period, but for millions of years. Because it is filled with deep sediment Promises to create an unbroken record of Arctic paleoglymata It involves many glacier-glacier cycles.

The name of the lake has changed over the years. It was called first Sub groove A diamond hunter and the first person to arrange a trip there: Frederick W Chub. Sub He expected there to be a crater from the extinct volcano, in which case diamond deposits similar to those in South Africa might be in the area. So, along with the geographer V. of the Royal Ontario Museum. Pen fish, In 1950 he made a brief flight to the abyss. It was during this voyage that Fish proposed the names Setter of Sub and Museum Lake. To an unusual body of water about 2 miles north of the abyss known today as Lake Laflamme.

On his return, the fish Arranged a trip The main place along with National Geographical Society and the Royal Ontario Museum. They arrived at the scene on a PBY Catalina seaplane July 1951, Landing at the nearby Museum Lake. Tried to find pieces of the trip Nickel-iron from meteorites using mine detectorsBorrowed from the U.S. military, but the search failed The granite in the area contains a lot of magnetite.

However, a magnetic field study found a magnetic anomaly below the northern edge of the abyss. Claims to be a large metal-bearing material buried below the surface.

He then directed the fish Second trip to the valley in 1954. In the same year, it was renamed Cratère du Nouveau-Quebec (“The new Quebec trench “) At the request of the Department of Geography in Quebec. It was only in 1999 that it was renamed Pingualuit, which translates to “the place where the earth rises”.

Author Reinhard Baints of Laval University He made a trip to the abyss in 2007 and recovered sedimentary nuclei from the lake bed, which were infested with fossil pollen, fossil algae and insect larvae. These findings are expected to provide Climate change information Goes back 120,000 years ago. Preliminary results show that there are records of two alternating periods in the upper 8.5 m sedimentary center.
