maars, including the readily accessible Lake Pupuke in the North Shore suburb of Takapuna. One of the most notable craters misidentified as a maar is Arizona's Meteor Crater; for many years this was thought to be of volcanic rather than meteoric origin. Germany Eifel maars In the Volcanic Eifel there are about 75 maars. These include water-filled maar lakes, but the great majority are dry maars. Both types, lake-filled maars and dry maars, are typical of the Volcanic Eifel. The last eruptions took place at least 11,000 years ago and many maars in the Eifel are clearly older. For this reason many are very heavily eroded and their shapes and volcanic features are not as obvious as those of more recent or even active maars elsewhere in the early. Nevertheless, the maars of the Eifel are well preserved. Water-filled maars of the Eifel Dry maars of the Eifel In the Eifel and Volcanic Eifel there are numerous dry maars: Mosbrucher Weiher (4 km SE of Kelberg) Booser Doppelmaar (W of Boos; near Kelberg) Dreiser Weiher (W of Dreis-Brück, N of Daun) Dürres Maar (SW of Gillenfeld) Duppacher Weiher (near Duppach, NW of Gerolstein) Geeser Maar (E of Gerolstein, N of Gees) Eckfelder Maar (near Eckfeld) Eigelbacher Maar (near Kopp, county of Daun; maar basin: c. 1200 m × 1200 m) Hitsche Maar (NW of the Dürre Maar, smallest Eifel maar; Ø = 60 m) Immerather Risch (Middle Low German: risch = reed bed; N of the Immerather Maar) Gerolsteiner Maar (NE of Gerolstein) Schalkenmehrener Maar E (of Schalkenmehren) Schönfelder Maar (SW of Stadtkyll-Schönfeld) Steffelner Laach or "Laach Maar" (near Steffeln) Dehner Maar (near Reuth) Walsdorfer Maar ("Schilierwiese"; S of Walsdorf; maar basin: c. 1150 m × 1000 m) Wollmerather Maar (near Wollmerath) Broader use of the term maar The following volcanic features are often colloquially referred to as a "maar" or "maar lake", although they are not, strictly speaking, maars: Windsborn Crater Lake and Hinkelsmaar in the Manderscheid Volcano Group near Bettenfeld, crater lakes of the Mosenberg Laacher See near Maria Laach, lake in a caldera of the Laacher See volcano Strohner Märchen (south of the Pulvermaar), volcanic pipe which has become a maar Papenkaule, a volcanic crater, and the associated eruption site of the Hagelskaule Elfenmaar near Bad Bertrich, an almost entirely eroded stratovolcano Rodder Maar near Niederdürenbach, the origin of which is unclear Maars outside the Eifel In
