Although Reported A Few Days Ago,

I am posing this today as there is a nice video of the phenomenon,

 it is a huge ice circle, we have in fact featured them before, 

 this on is worth mentioning because of the shear size

of it, 

 it was discovered in a section of the Presumpscot River in Westbrook, Maine, USA,

the floating patch was recently captured by the city in an aerial video, in the footage a nearby parking garage seems dwarfed by the mammoth proportions of the circular ice patch, according to Westbrook’s marketing and communications manager Tine Radel, the icy island has been spinning in a counterclockwise direction, and does not appear to be moving up or downstream, You can view an aerial tour of the floating ice patch in the video produced by the City of Westbrook below, 

all images via City of Westbrook, what an amazing sight, you never know if the next few months are as cold as predicted, we might even have one in the River Thames!
