Ice Break-up in Bush Alaska

Each year, breakup along the Yukon means the ice is taking over the river.  Here is a video of ice moving and it goes where it wants.  It can take over a town and destroy whole villages in a matter of minutes.  The apartment which I lived in in emmonak was flooded a couple of times.  Break up in village Alaska is a big deal.
