Double Rainbow

A beautiful sight, occurring when a sunlight reflects through a raindrop twice. Most clearly seen when the rain clouds in the sky are still dark so the fainter light and shape of the arc can be more clearly seen. Striped Iceberg

Icebergs are traditionally thought of as a floating, sea mountain that caused the Titanic to sink. However, these unusual striped icebergs are made when water freezes over an already frozen iceberg, picking up dirt and other particles along the way. Blue stripes are made when water becomes trapped between layers of ice and is frozen so fast that air bubbles can't form. Green or yellow stripes are made from other materials in the ocean, such as algae. Green Flash

Appearing for a split second, the Green Flash is a rare phenomenon that you could plan to see. It occurs only at sunset and sunrise and is due to the sun's light travelling through the earth's atmosphere to create a prism effect. Scottish legend dictates that if you were to see the green flash, you would gain the power to read other people's souls... although it hasn't happened to anyone yet. Columnar Basalt

During the cooling of thick lava, it has been known to contract vertically. The formations then crack and present themselves as square pillars that appear to be man-made. Slower cooling is likely to make wider columns. You can see this on the Giant's Causeway in Ireland and the Devil's Tower in Wyoming. Blue Holes

A blue hole is much alike an underwater cave or sinkhole. They are circular and are so-named because the sudden depth of the sea makes the water look a dark blue. The water circulation is poor and it is not an ideal climate for life, however large numbers of bacteria have be found to survive. Penitentes

Penitentes are tall, thin columns of hardened snow which look as if they are growing towards the sun. These formations range in different size from just a couple of centimeters to over 5 meters or 16 ft. First described in literature by Charles Darwin, these strange ice structures are found mainly in the Dry Andes although have been known to grow in other places too.
