Many icebergs are dimpled, like a golf ball but not as regular. I wonder why this is. What is the physical nature of an iceberg or what about the melting process results in these dimples?
Do any of you know?
Something else I found interesting was that when I touched the giants in the upper lagoon, the surface was smooth and cold but not the least bit wet. When I took my hand away, there was no hint of moisture on it. I suppose it makes sense given the temperature, but it was an interesting sensation.
