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 numerous sinkholes clustered around the trough of the crater suggest a prehistoric oceanic basin in the depression left by the impact. The Chicxulub crater (pronunciation: /ËtÊiËkÊáµ¿luËb/; Mayan: [tÊÊ¼ikÊuluÉ]) is an impact crater buried underneath the YucatÃ¡n Peninsula in Mexico. Its center is located near the town of Chicxulub, after which the crater is named. It was formed by a large asteroid or comet about 10 kilometres (6 miles) in diameter, the Chicxulub impactor, striking the Earth.
