Toolik Lake is thawing from the winter freeze that was about 2 meters thick. Toolik Lake's top layer ice is thawing and breaking apart and much of the ice is going downstream.

While the lake thaws it creates what is called candle ice.

Candle ice develops in columns perpendicular to the surface of the lake. They make a clinking sound when the candles are broken apart and float in the water bumping into each other.
