LINWOOD, MI — A video posted to Facebook on Sunday, Feb. 3, shows people on snowmobiles driving over open water at a crack in the ice of frozen Saginaw Bay.

Nate List, the man who recorded the video, said the crack is a little more than two miles offshore, east of Linwood Road.

List received more than 450 shares on his Facebook post of the video for the Saginaw Bay Michigan Fishing group.

In a local weather group on Facebook, people were reporting that rescuers were reporting to a crack in the ice near Erickson Road and expressed safety concerns for those on the ice.

Officials for the Department of Natural Resources and U.S. Coast Guard Saginaw River Station could not be reached for comment.

Officials at the Saginaw Fire Department warn against crossing any cracks on frozen bodies of water.

“The wind and conditions can change in a matter of minutes and widen the crack, making it not possible to cross back over,” said Lt. William McCarthy. “You should never cross a crack if you see them.”
