 20 square miles, Ahura Gorge, if the arc is even partially down in there, that's 10 Grand Canyons in size. Yeah, that's huge. Just a massive amount of surface area to comb. A lot of ice, too. How high is the ice out there? Well, the ice can range from 30 feet to hundreds of feet. And as it is ice, it's moving. It's constantly in a moving state.
