Brent Crater

450 BCE

The Brent crater is an impact crater in both the geographic township of Deacon, Unorganized South Nipissing District and the municipal township of Papineau-Cameron in Nipissing District, northeastern Ontario, Canada, located north of Cedar Lake in northern Algonquin Provincial Park.

Pilot Crater

445 BCE

Pilot crater is an impact crater in the Northwest Territories, Canada, just north of the Alberta border and near Fort Smith 54 km. It is 6 km in diameter and the age is estimated to be 445 ± 2 million years. The crater contains Pilot Lake, a pristine fresh-water lake that covers 43 km² and is 90 m deep.

Saint Martin Manitoba

227 BCE

Saint Martin is an impact crater in Manitoba, Canada. It is located in the northern part of the Rural Municipality of Grahamdale, northwest of Lake St. Martin. The crater is 40 km in diameter and its age was determined to be 227.8 ± 1.1 million years using the argon-argon dating technique.

Viewfield Crater

190 BCE

Viewfield is an impact crater in Saskatchewan, Canada. It is 2.5 km in diameter and the age is estimated to be 190 ± 20 million years. The crater is not exposed at the surface

Carswell Crater

115 BCE

Carswell is an impact crater within the Athabasca Basin of the Canadian Shield in northern Saskatchewan, Canada. It is 39 kilometres in diameter and the age is estimated to be 115 ± 10 million years. The crater is exposed at the surface

Deep Bay

99 BCE

Deep Bay is a bay near the south-western tip of Reindeer Lake in Saskatchewan, Canada. The bay is strikingly circular and very deep in an otherwise irregular and shallow lake. It is the deepest body of water in Saskatchewan. The bay was formed in a 13 km wide impact crater.

Maple Creek Crater

75 BCE

Maple Creek is a subterranean meteorite crater in Saskatchewan, Canada. It is 6 km in diameter and the age is estimated to be less than 75 million years. The crater is buried beneath younger sediments and cannot be seen at the surface

Wanapitei Saskatchewan Crater

37 BCE

The crater is 5.2 mi (8.4 km) in diameter and the age is estimated to be 37.2 ± 1.2 million years, placing it in the Eocene. It was evident by the mid-1970s that Wanapitei Lake was an impact crater. Remarkably, it lies on the eastern edge of the much older, larger Sudbury structure.

Haughton Crater

32 BCE

Haughton impact crater is located on Devon Island, Nunavut in far Northern Canada. It is about 23 km in diameter and was formed 31-32 million years ago during the Early Oligocene. The impacting object is estimated to have been approximately 2 km in diameter.

Whitecourt Crater

1080

Whitecourt crater is a meteorite impact crater in central Alberta, Canada, located approximately 10 km (6.2 mi) southeast of the Town of Whitecourt within Woodlands County. It is remarkable for being unusually well-preserved for a crater of small size and relatively young age.
