Overflight – Pingualuit Impact Crater (AKA: Chubb, New Quebec):
In Northern Quebec, Canada, there is a pristine simple crater that in 1999 was renamed the Pingualuit Meteorite Crater. It is visible as the small circular structure in the mid-right side of this image, and is larger than the smallest crater on the moon that is visible by telescope from earth. The crater is 3.44 km in diameter with a depth of 400 metres. The lake which occupies the crater is 267 metres deep and it is Quebec’s deepest lake. The crater rim is over 100 metres above the surface of the enclosed lake with a pitch of 40 to 45 degrees down to the water. Uplift from the original impact extends outward to a distance equal to almost twice the diameter of the crater
Overflight – Holleford Impact Crater
The <30 metres depth of the “bowl” shape of the impact structure becomes evident while flying by the structure at lower altitudes. Over a half-billion years of sediment covers the original crater. I have to admit that the first time I flew to this impact structure I had a difficult time in finding and identifying the feature.
Overflight – Brent Impact Crater
The Brent meteorite crater is located within the northern boundary of Algonquin Park 75 km east of Lake Nipissing. It was named the “Brent crater” because of its proximity to the village of Brent, a divisional point on the Canadian National Railway’s transcontinental line. It is the largest known terrestrial crater with a simple, bowl-shaped form and perhaps the best known and possibly the most thoroughly studied fossil meteorite crater in the world.
Overflight – Algonquin Radio Observatory
The Brent Impact Crater is a short 1.5 hour flight north of Ottawa. On the way the circular white shape of theAlgonquin Radio Observatory at Lake Traverse is very obvious. I’m dating myself, I had a tour through the complex when it was operational in the early 1970’s.
