Ice eggs covered this Finland beach
Thousands of unusual egg-shaped ice balls were discovered on a beach in northern Finland. The ice balls, which cover much of a beach on Hailuoto Island near Oulu, usually form when pieces of ice interact with sea water under the right conditions. Risto Mattila, an amateur photographer, was among those who discovered these “ice eggs.”
This is located in the Gulf of Bothnia, which connects Finland and Sweden. These balls are caused by a rare process in which small pieces of ice are rolled over by wind and water, and they cover an area of about 30 meters (100 feet). The smallest were the size of eggs, while the largest were like footballs.
