Bizarre Borders

Joseph Thacker 's curator insight, January 30, 4:29 PM

Glad to see two countries like Canada and America can get along over these bizarre borders. I think many countries in the Middle East would fight over those small pieces of land. I think we avoid violence over these borders because we have such a good relationship with Canada.

Nathan Chasse's curator insight, February 1, 4:28 PM

The video highlights a bunch irregularities along the US/Canadian border. Among them, the zigzag 49th not-so-parallel, a small island which is actually a disputed territory, and another US island which is far closer to Canada than it is Washington state causing high school students to have to cross international borders four times to attend school.



This is an interesting video in that it shows how even in the recent past how difficult it was to clearly and conclusively delineate the border between the US and Canada. The fact that there is still a disputed island between two very friendly nations. This only makes it more clear why much older, less friendly nations would have heated disputes over territory.

Did you know the geometric boundary between US and Canada (the longest border in the world) is also a physical border? Check it out.

Astrobleme

Astrobleme | HMHS History | Scoop.it

"Lake Manicouagan lies in an astrobleme in central Quebec covering an area of approximately 1206 square miles—an area half the size of Delaware. An astrobleme is a scar left on the Earth’s surface from an impact of a meteorite. Lake Manicouagan is the result of one of the largest identified asteroid or comet impacts on Earth. In the middle of the lake, on Rene-Levasseur Island, Mount Babel rises 3,123 feet into the air.

 

Lake Manicouagan is thought to have formed about 212 million years ago plus or minus 4 million years.  This happened when an approximately 3.1 mile-diameter asteroid crashed into Earth toward the end of the Triassic period. Some scientists speculate that this impact may have been responsible for the mass extinction that wiped out more than half of all living species."

Al Picozzi's curator insight, September 18, 2013 5:33 PM

This amazing picture shows how vulnerable the earth is to space born hazards.  This 3.1 mile-diameter asteroid might have caused 1/2 the living species on the earth at that time, 212 million years or so ago, to become extinct.  Man has the abilty to adapt to changes to the environment, unlike the dinosaurs.  The question is though do we have the ability to adapt to an event of this magnitude?  Hopefully we will not have to test out this question.
