Ice has covered Tahquamenon Falls in Michigan's Upper Peninsula.

"The water is flowing beneath the ice, but we have never seen the left side froze over before," the Tahquamenon Falls State Park posted on Facebook on Tuesday.

On Saturday, the park posted a photo of the falls mostly frozen over. Ice started to form on Jan 22 and most of the falls became covered by Friday.

The falls are not 100 percent frozen over, said Tahquamenon Falls State Park manager Craig Krepps. There is a small, 5-foot channel on the north side of the falls.

On Wednesday, the state park posted a photo of the falls totally covered. The 48,000-acre park has 296 campsites and a 34-mile trail system.

Tahquamenon Falls is located near Paradise, Michigan, about 80 miles north of the Mackinac Bridge. It is considered one of the most beautiful sights in the state.

Extreme cold has hit Michigan in the past few weeks. The Great Lakes are also covered in ice. As of Monday, Feb. 23, 2015, the total Great Lakes ice cover was 85.4 percent, according to MLive Meteorologist Mark Torregrossa.

The cold will continue this week, with temperatures dropping -7deg and -20deg in the southern half of Lower Michigan.
