If you like ice, you have to love the Great Lakes, where it comes in all shapes and sizes. With the recent deep freeze, we're seeing a lot more ice than in the past few winters -- including a frosty Niagara Falls. ​Here's a look at some unusual shapes and sizes:

The Great Lakes/St. Lawrence River make up the world's biggest freshwater system -- and an enormously valuable resource. It supplies drinking water for millions of residents and powers the region's economy.

Last year, 42 million gallons were withdrawn from the basin each day, according to a new report from the Great Lakes Commission. Here's where it went.

The Christmas spirit is popping up along the waters of the Great Lakes region.

In Port Huron, Mich., Santa Claus rode to shore on the Huron Spirit, a boat operated by the Lakes Pilots Association. In Toledo, Ohio, the tug Josephine brought him to the National Museum of the Great Lakes.

But the most poignant event of the holiday season was in Chicago, where the sinking of  "The Christmas Tree Ship" was remembered recently.

As America confronts the opioid crisis, environmental scientists are warning about a related problem. Chemicals from pain-killers and other drugs often end up in lakes and rivers, creating what some scientists say could be a deadly cocktail for fish and other wildlife.

Over the past two winters, the Great Lakes have had a below-average ice cover. And that’s expected to continue this year.
