I love this picture, because it has so many levels of thought and understanding to it. At first glance, it's this totally awesome picture of blue and white, ocean and sky, awe and power. Looking closer, there's an iceberg poking it's head out of the water's surface. Looking closer, there's the rest of the iceberg, huge and massive lingering below the ocean's surface. I've heard it said that only half of the iceberg is visible above the water, and that people don't realize there is just as much mass sitting below the surface as well. That's what got the Titanic - the mass of iceberg under the water that couldn't be seen. Imagine how cold the water must be to maintain so much ice in it's depths. How quickly might that iceberg disappear if the water heats up even a degree or two? Where will the mass of all that frozen water go when it thaws? Will our descendants ever see this amazing sight?
