The Kerio Crater Lake in Iceland. The Kerio Crater Lake (sometimes spelled Kerid) is located in the GrÃ­msnes area in south Iceland, and is one of the most photogenic volcanic crater in existence. Itâs a regular stop for tourists along the Golden Circle sightseeing route and one of the most-photographed features in this amazing landscape.
The crater has been named the Barringer Crater in honor of Daniel Barringer, who was first to suggest that it was produced by meteorite impact. It is also referred to simply as Meteor Crater. The crater is located approximately 69 km east of Flagstaff, near Winslow in the northern Arizona desert of the United States. It is the largest impact crater yet discovered in the United States, and one of the best preserved on earth.
