Now this is a sound to fall asleep to.

I always think the sound of waves on Lake Michigan are a beautiful thing, but there's something particularly calming about this video taken at Glen Haven beach in Sleeping Bear Dunes National Lakeshore.

Last week we shared with you photos ice of balls in Lake Michigan off of South Pier in St Joseph captured by photographer Joshua Nowicki.

According to Atlas Obscura,

When the Great Lakes get cold like this, water transforms into unusual ice formations on the surface of the lakes...Ice boulders form when cold chunks break from ice sheets, and the movements of a lake’s waves sculpt those pieces into rounder shapes. The balls can also accrue more layers of ice, growing large."
