Ice eggs -- Gulf of Bothnia

Another in our series of photos of strange snow and ice phenomena.  Ice eggs on the coast of an island in the Gulf of Bothnia, near the coast of Finland.  Very rare -- they are formed when fragments of snow or ice on a freezing shore are detached and roll around on the beach under the influence of strong wind and waves.  Once the sea freezes over completely, this process becomes impossible.  So it's an autumnal phenomenon -- but it may not happen again for several decades, anywhere in the world.......
