striped icebergs...without having come across this before, my (too tall) brother would probably be able to tell me why the icebergs formed this way:

for the rest of us...the white of the iceberg occurs because tiny bubbles become trapped as the water freezes. the blue stripes occur when the ice melts, the bubbles are released, and then the water quickly refreezes. green stripes are from salt water and other colored stripes include different kinds of sediment.

bottom line...nature is pretty amazing.
