Crater Lake (Klamath: giiwas) is a caldera lake in south-central Oregon in the western United States. It is the main feature of Crater Lake National Park and is famous for its deep blue color and water clarity. The lake partly fills a nearly 2,148-foot (655 m)-deep caldera that was formed around 7,700 (± 150) years ago by the collapse of the volcano Mount Mazama. There are no rivers flowing into or out of the lake; the evaporation is compensated for by rain and snowfall at a rate such that the total amount of water is replaced every 250 years. With a depth of 1,949 feet (594 m), the lake is the deepest in the United States. In the world, it ranks ninth for maximum depth, and third for mean (average) depth.

Some family names do exist in Iceland, most commonly adaptations from last name patronyms Icelanders took up when living abroad, usually Denmark. Notable Icelanders who have an inherited family name include former prime minister Geir Haarde, football star Eiður Smári Guðjohnsen, entrepreneur Magnús Scheving, film director Baltasar Kormákur Samper, actress Anita Briem and member of parliament (and former news reporter) Elín Hirst. Before 1925, it was legal to adopt new family names; one Icelander to do so was the Nobel Prize-winning author Halldór Laxness, while another author, Einar Hjörleifsson and his brothers all chose the family name ``Kvaran''. Since 1925, one cannot adopt a family name unless one explicitly has a legal right to do so through inheritance. (The law was amended in 1991 and 1996.)
