We spotted this iceberg in Cierva Cove, Antarctica while scouting in a Zodiac boat. The iceberg looked more like an alien-artifact than a typical, all-white block of ice. Our guide explained that this iceberg had recently flipped; its color likely the result of frozen seawater and organic matter, freezing deep on the ice shelf. Of the thousands of icebergs we saw during our time there, this was far and away the only one that possessed this jeweled appearance. It was probably the most incredible thing I have ever seen -- I hope the pictures do it justice.
