Jökulsárlón is the largest glacier lake in Iceland. Situated in south eastern Iceland, 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. The size of the lagoon has increased fourfold since the 1970s. It is considered as one of the natural wonders of Iceland.
