Icebergs

[plbh]

We took a trip to east Greenland last year. The scenery was fantastic, and what really made an impression were the icebergs, which come in such a variety of shapes and textures. I'll post some examples here, and I hope some of you will add your own and maybe teach me something about them.

Surfaces can be freshly fractured or smoothly melted below old waterlines:

Icebergs are pieces broken from glaciers, which are ancient compressed snow, white from the trapped air bubbles. Cracks that fill with meltwater freeze into translucent blue ice.

I guess the ice layers in the glacier must vary in hardness, so they can melt into something like this:

Meltwater can form underground rivers through glaciers that become iceberg caves:

This one has embedded flat dirty layers that I assume were originally deposited on the surface of the glacier; I'd love to learn more about it:

Here's where those icebergs from Greenland end up....off the coast of Newfoundland
