These massive snow boulders, estimated to be about 75 pounds, have washed ashore off the coast in northern Michigan.
The stunning snowballs were spotted by a woman who was walking her dog at the Sleeping Bear Dunes national park.
'I thought it was the coolest thing ever especially since I've never seen anything like it,' said Leda Olmstead. 'I have a small English bulldog and they were as tall as her. They were pretty massive.'
