DR Sarah Parcak a archeologist is passionate about finding  ancient settlements under the sands. She uses a satellite technology as a resource to find these ancient settlements. It can be either pyramids, temples, or just statues.

It is interesting to find out that in this specific article there is controversy over the looting of tombs over 5,000 years ago as soon as the deceased were buried there were many more looting acts taken place. The Arab spring is an important landmark to think of when relating this to the reading.

This describes human characteristics that defined this region because it shows how ancient artifacts are being unearthed through new-age technology.

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.
