Meteor Crater Discovered in Southern Alberta Likely had Global Impact

Posted: Updated:
A geologist mapping southern Alberta for their geological survey stumbled across what could be an earth changing meteor crater. Not the largest of such craters because glaciers and erosion has claimed its shape, but an impact area of nearly 2 miles is said to be the spot where a large meteor struck the earth in the last 70 million years. Scientists are unclear exact when it happened because the area has changed so much, but they do seem confident that this meteor was large enough to have global impacts.

Located near the town of Bow City, it sits about 150 miles southeast of Calgary and about 300 miles from Edmonton. If this meteor hit today, scientists believe that the city of Calgary would have been decimated with Edmonton taking severe damage. The impact sight is close enough to the U.S. that much of Montana and North Dakota would have been impacted too. Not to mention, the effects of the explosion could have affected the globe for decades with a “nuclear winter” type scenario. This is now one of 8 known craters in Canada, and about a dozen in North America. This one still pales in comparison to the meteor that is believed to have wiped out the dinosaurs with the nearly 100 mile wide crater said to be in the Gulf of Mexico.
