The U.S. Forest Service has warned Juneau residents to avoid the Mendenhall Glacier due to a large crack that could lead to significant calving, posing risks to those recreating on the frozen lake.

A window of cold and clear weather has drawn hundreds of people to skate, bike and walk on the lake ice in recent days.

A person is missing after a vehicle fell through the ice on Lake Laberge in Yukon. Two others managed to escape.

The ice may look solid, but emergency officials are warning Yukoners to be wary. M.A. Chartrand learned that the hard way last week.
