Jökulsárlón is the famous lake of ice at the south end of the Vatnajökull glacier. Appearing first only in 1934-1935, the lake grew from 7.9 km² in 1975 to at least 18 km² today because of heavy melting of the Icelandic glaciers. Approaching a depth of 200 m, Jökulsárlón is now probably the second deepest lake in Iceland.
