Isla Guadalupe
Guadalupe Island or Isla Guadalupe is a volcanic island located 241 kilometres off the west coast of Mexico's Baja California Peninsula and about 400 km southwest of the city of Ensenada in the state of Baja California, in the Pacific Ocean. The various volcanoes are extinct or dormant. In 2005 Guadalupe Island and its surrounding waters and islets were declared a biosphere reserve to restore its vegetation and to protect its population of marine mammals and birds. The island is a popular destination for white shark cage diving. Guadalupe Island is inhabited only by scientists, military personnel operating a weather station, and a small group of seasonal fishermen. The island is mostly arid and has very little surface water. The two other Mexican island groups in the Pacific Ocean that are not on the continental shelf are the Revillagigedo Islands and Rocas Alijos. Guadalupe Island and its islets are the westernmost region of Mexico.
