Jökulsárlón glacier lagoon, Iceland

Jökulsárlón is the largest glacier lagoon in Iceland. Situated in south eastern Iceland, at the head of the Breiðamerkurjökull glacier branching from the Vatnajökull, between Skaftafell National Park and Höfn, it evolved into a lagoon after the glacier started receding from the edge of the Atlantic Ocean. The lake has grown since then at varying rates because of melting of the Icelandic glaciers. The lagoon now stands 1.5 kilometres away from the ocean's edge and covers an area of about 18 km2. It is the second deepest lake in Iceland at over 200 metres deep. The size of the lagoon has increased fourfold since the 1970s. It is considered as one of the natural wonders of Iceland.
