The picture was taken the last day of March. I have never seen The Pond with as much bad ice this early. The open hole is from methane release, which caused the ice to thin just above the methane pocket.
The Nenana River has some open water already, downstream from the Ice Classic Tripod. The earliest the Tanana River has gone out is April 20. Short of an epic cold snap, that record will be broken in 2019.
