Beneath a section of Chicago, there is a hidden several mile wide impact crater. This might initially seem like a crazy claim but it is true, existing underneath the city of Des Plaines. The only reason it isn't highly visible today is due to sediments emplaced during extensive glaciers during the last 2 million years. It is for this reason that I will discuss when this crater formed, what evidence we have, and what immediate effects its formation had.

Estimates on asteroid diameter, velocity, tnt energy equivalent, frequency of a similar magnitude asteroid/comet impact event, and effects from the impact (including earthquake magnitude generated and wind speeds generated) in this video were sourced using the calculator at Earth Impact Effects Program, which was used with permission.

The impact was so devastating that it darkened the skies for years and killed off the White Sox's hopes forever.

What do you mean? They have won three World Championships since then.
