Icebergs

Icebergs in Davis Strait by Lauren Harris

Lauren Harris was a member of Canada's renowned Group of Seven painters. At first glance, Harris's impression of an iceberg seems fanciful. Green and blue stripes? Clearly this is artistic license at work. No, it isn't.

Icebergs have different colours based on the particulate in the water or snow pack that formed them.  Also if an iceberg has flipped over and its bottom is now on top, it will have different colours showing from the sediment picked up while bumping along the sea bed, or it will have algae which also gives it colour. There are all kinds of scientific ways to describe what makes an iceberg striped and tinted but really, icebergs are all about the colours and shapes and how they are positioned in the water, aren't they?

I wonder how many bergs are out there with a preserved mammoth in them

Not real in a really real life kind of way

Interesting side point: Perhaps you've seen images of this 'iceberg' (above) while surfing around the net. Or maybe you've had it forwarded to you by a well meaning elderly Aunt with only enough computer knowledge to make her dangerous? Thank the internet for Snopes. As they explain:

This image was produced in 1999 by Ralph A Clevenger, a professional nature and underwater photographer. Mr. Clevenger explains that this image is not a single photo but a composite of four different photos (not all taken in the same place).
The iceberg image is a digital composite that I designed to illustrate the concept of "what you see is not necessarily what you get". As an underwater photographer I knew that my "vision" of what a big iceberg looks like was impossible to get in reality so I had to create it. The image exists in nature but due to water visibility is not possible to capture on film.
There are 4 separate images involved: the sky, the background, the top iceberg (shot in Antarctica) and the underwater iceberg shot above water in Alaska and flipped in the final composite).
The idea that most of an iceberg is below the surface of the water is correct and one only has to observe ice cubes in a glass of water to see it. In this particular case the photo is not real but only presented as a representation of that fact.

There is so much beauty in this world of ours, isn't there?

When I come face to face with how much ugly there is in this world, it always makes me happy to know that beauty exists here and many places of unsung beauty are here also. Even if I'll never be able to visit such places, knowing they're sharing our planet is a comfort.
