Lake Jökulsárlón shimmers with the reflection of a magnificent iceberg. This lake, located at the edge of Vatnajökull, Iceland’s largest ice cap, formed slowly when part of the glacier began to recede in the 1920s. The glacier continues to calve (split), releasing more icebergs into the expanding lake.
