Pingualuit Crater Lake Facts
- Pingualuit Crater Lake represents an astonishingly pristine lake filling an enormous crater that actually formed from a meteorite impact nearly 1.4 million years ago.
- This lake is a remarkable geological site. One of its most noteworthy features remains its complete lack of either inlets or outlets. The water levels stay maintained entirely by precipitation and evaporation. This happens extremely rarely.
- It also has an incredibly low acidity level in comparison with most other lakes. As a result, the water stays extraordinarily clear. In fact, this lake has been called one of the clearest lakes in the world.
- The site used to be known as the Chubb Crater. The name changed to its current one in 1999. The name comes from the language of the indigenous Inuit people.
Pingualuit Crater Lake Description
Pingualuit Crater Lake sits amid a landscape that has been described as “lunar.” Yet this desolation only serves to highlight its beauty.
The crater itself forms an almost perfect circle. It should also be noted that the crater measures an astonishing 2.1 mi (3.4 km) in diameter.
The walls of the crater measure 1,300 ft (400 m) high. These walls also rise roughly 521 ft (159 m) above the surrounding terrain. The lake itself averages nearly 876 ft (267 m) deep.
The water contains a salinity level of less than 3 ppm, which ranks among the lowest on earth. As a result, the water always appears remarkably clear. Objects as deep as 115 ft (35 m) are visible to the naked eye.
Pingualuit Crater Lake Formation and Mystery
Pingualuit Crater Lake can be found on the Ungava Peninsula, in Canada.
The impact that created it occurred 1.4 million years ago. The impact itself also seems to have been unique. Rather than striking at an angle, the object struck the earth almost perfectly vertically. A nearly circular crater formed as a result of the impact. Analysis of the rocks indicates the meteorite was of the chondrite type.
As a result of glacial activity during the last ice age, the crater filled with ice. Consequently, the withdrawal of the ice left the crater filled with ice. The lake formed from the melting ice, and now comprises an entirely closed system.
One last mystery involving the lake remains. A single species of fish inhabit the lake. They have adapted to survive with minimal sources of food. How they came to inhabit the lake remains a mystery.
