Finland – Thousands of egg-shaped balls of ice covered a beach here as a result of a rare weather phenomenon.
Experts said it was caused by a rare process in which small pieces of ice are rolled over by wind and water.
Amateur photographer Risto Mattila was among those who came across the “ice eggs” on Hailuoto Island in the Gulf of Bothnia between Finland and Sweden.
Mattila said the balls of ice covered an area of about 30m (100ft). The smallest were the size of eggs and the biggest were the size of footballs.
Similar sights were reported before, including in Russia and on Lake Michigan near Chicago.(BBC)
