How often do you see a glacier this close? Glacial ice can range in age from several hundred to several hundreds of thousands years. But sadly they are disappearing fast due to global warming. I'm afraid our grand children will never get to see them. Breiðárlón is a glacier lake at the south end of the Icelandic glacier Vatnajökull. The glacier calving into the lake is a part of mighty Icelandic glacier Vatnajökull at the south end of the Vatnajökull National Park.
