14 DAY TRIAL // Towards the end of last year, a small army of massive ice boulders formed in the waters of Lake Michigan in the US. Despite the fact that such ice balls have many times before come into being in this body of water, this latest batch turned out to be just as popular as its forefathers.
Thus, a video showing several ice boulders swarming the shores of Lake Michigan is now going viral on social networking sites. The footage in question, obtained on December 31, 2014, and shared with the online community shortly after, is available below.
As explained by scientists, the mammoth ice balls were created when temperatures in the region dropped to a considerable extent, and consequently, small chunks of ice formed in Lake Michigan's waters. Eventually, these ice fragments grew to become regular boulders.
It is understood that, in order to grow to reach such an impressive size, chunks of ice birthed by low temperatures simply have to float about and get hit by waves that deposit water on their surface. If temperatures are low enough, this water instantly freezes and the chunks grow in size.
What this means is that, essentially, the ice fragments grow to become ice boulders much like snowballs do when rolled down a slope. What's interesting is that, as long as environmental conditions are right, they stand to go on getting bigger.
