The dimpling showing up on an iceberg is an indication that the berg has turned upside down. This used to be the underwater side. Wouldn't want to be too close when this monster turned over. What a wave that would have been! What an amazing sight! This is a trip to show the beauties created by nature in their most awesome setting. When a friend questioned me about what I saw there and I said BEAUTY, she questioned what possible beauty was down there. Magnificent, indescribable shapes and glowing blue colors far beyond my expectations!
