Ice thickness on the Chenr River downtown is 21″.

We have 2 feet of snow pack at the airport, which provides considerable insulation. The overflow that Bob Baker encountered on Sunday was only 4 to 6 inches deep. This cold spell will solidify that now that he had packed down the snow overlying it. Don’t panic. The Sonot Kkaazoot is still six weeks away and Mother Nature hasn’t revealed all her secrets yet.
