Long Description:
"The Charlevoix crater is a large eroded meteorite impact crater in the Charlevoix region of Quebec, Canada. Only part of the crater is exposed at the surface, the rest being covered by the Saint Lawrence River.

The original crater is estimated to have been 54 kilometres (34 mi) in diameter and the age is estimated to be 342 ± 15 million years (Mississippian).

The projectile was probably a stony asteroid, at least 2 kilometres (1.2 mi) in diameter, and weighing an estimated 15 billion tonnes (1.7×1010 short tons).

The crater is classified as a multi-ringed basin with a central uplift.

The impact origin of Charlevoix crater was first realized in 1965 after the discovery of many shatter cones in the area. Other evidence for impact includes planar deformation features in quartz and feldspar grains.

In contrast to the surrounding craggy Laurentian Mountains, the crater is relatively smooth and flat, which has facilitated human settlement. Today, 90% of the people of Charlevoix live within this crater."

"Situé à 105 km au nord-est de la ville de Québec, la moitié de ce cratère de 56 km de diamètre s'étend sur la rive nord du fleuve Saint-Laurent, l'autre moitié étant située sous l'eau du fleuve. La partie du cratère située au nord du fleuve est bien conservée alors que la partie sous le fleuve est fortement érodée.

La météorite à l'origine de la formation du cratère de Charlevoix est probablement un astéroïde de 2 kilomètres de diamètre, masse de 15 milliards de tonnes arrivant à une vitesse de 10 à 20 km/s (soit environ 60 000 km/h). L'énergie dégagée au moment de l'impact représente 20 millions de mégatonnes de TNT (c'est-à-dire des milliers de fois la puissance combinée de tous les arsenaux nucléaires)."
