As I close my series on Antarctica, I’d like to offer one more image of this dramatic destination. This blue iceberg is one of my favorite photos from Antarctica. Our two rubber Zodiacs set off one morning to cruise around Cierva Cove. The bay was choked with icebergs ranging from tiny to gargantuan, but it was this mid-size one that caught my attention. Not only was it a gorgeous blue hue, it also had an almost perfectly circular hole at its base. Our captain hadn’t noticed the iceberg; he motored by without a glance. I tapped him on the shoulder. “Can we go back to that one, the one with the hole in it?” I asked.
The captain also seemed excited when he saw where I was pointing. He made a quick U-turn and signaled our buddy dinghy to follow. We asked why the ice was so blue. The naturalist on board our Zodiac explained that ice becomes more and more compacted over the centuries. Denser ice reflects light differently; the denser the ice the bluer the color. This blue iceberg must have been calved from a very old glacier. We circled it, one boat on either side of the hole, and began taking photos of one another. No single photograph can fully capture the magnificence of Antarctica, but I think this one comes close. I snapped away, trying to capture the essence of this ravishing and fragile environment through the window to this iceberg’s soul. Did I succeed? You will have to tell me.
