Good Harbor, Michigan - She's lived near the Sleeping Bear Dunes National Lakeshore for nearly seven years but a Northern Michigan woman says she's never seen anything like this.

Leda Olmstead came across dozens of ice boulders during her daily walk Thursday afternoon. The giant formations were scattered across a 100 foot section of the beach and were too heavy for her to pick up.

"I thought it was the coolest thing ever especially since I've never seen anything like it" Olmstead told WZZM 13. "I have a small English bulldog and they were as tall as her. They were pretty massive."

Olmstead says despite the often gray skies, cold temperatures, and lake effect snow, she loves Northern Michigan.

People think it's so boring and gross up here in the winter but I think it's beautiful," said Olmstead.

Olmstead posted the photos of the ice boulders on Facebook and the images quickly went viral, with hundreds of shares, likes, and comments. ABC News even called the WZZM 13 Information Center Friday afternoon looking to use the images in a newscast.

WZZM Chief Meteorologist George Lessens says the ice boulders likely started as small balls of ice in the lake, which grew in layers-- the way hail or snow balls form. Strong wind and waves likely caused the giant ice balls to wash ashore.
