The unique Diamond Beach, located by the Jökulsárlón glacier lake lagoon, is named for its natural ice sculptures that wash up on the lagoon shore and stand in sharp contrast to the volcanic black sand. As a consequence of climate change, the glaciers are retreating with everchanging scenery of incredible beauty and the size of the glacial lake has increased annually since its development approximately 60 years ago. The glacier lake is reported to have doubled in size in the last 15 years. Icebergs gather at the mouth of the lake’s shallow exit, melt into smaller blocks and float out to sea. The lake fills with herring trout, salmon and other fish brought in by sea tides and provide a food source for seals and a diverse variety of birds.
