A small compilation of five natural phenomena that will blow your mind!
1. Incredible Natural Phenomenon – Light Pillars in Finland

Light pillars are caused by the reflection of light by ice crystals in the air. Here another example of this amazing light phenomenon in Canada.
2. Incredible Natural Phenomenon – Snow Chimney or Fumaroles

Snow Chimney: Fumaroles are vents that allow steam from volcanoes to escape into the open as reported by twitterer Gotham 3. In Arctic areas, as soon as steam leaves one of these vents, it freezes, and eventually, massive snow chimneys are formed around the volcanic vent.
3. Incredible Natural Phenomenon – Frost Flowers

These unusual flower fields form on thin sea ice when the atmosphere is far colder than the underlying ice. When the warmer, wet air and overlying cold air meet, they form these amazing crystals.
4. Incredible Natural Phenomenon – Striped Icebergs in Antarctica

These beautiful blue stripes occur when a crevice in the iceberg fills up with water, which freezes so quickly that no bubbles form. Green stripes can form when algae attaches to an iceberg as it falls into the sea. Brown, black and yellow lines are caused by sediment that is picked up when the berg first travels down hills into the sea. You can watch some more pictures of icebergs here.
5. Incredible Natural Phenomenon – Volcanic Lightning

Volcanic plumes produce immense amounts of electrical charge and static. In rare cases, this can spark a violent lightning storm. More pictures and a video here.
