Update on the Landslide that Blocked a Major River in Canada; Expected Flood Heights

In Canada, it has not been 5 days since a landslide just blocked the major Chilcotin River. In the days since the initial slide, additional portions of the same hillside have also collapsed while at the same time the ever growing lake expanded to more than 9 kilometers in length. Due to the risk of this dam potentially bursting and causing hundreds of kilometers downstream, numerous alerts were put in place all the way to Vancouver. This video serves as an update with new information, as we now know the expected worst case scenario flood heights for when this disaster occurs.
