Tiburón and Archangel Islands in the Gulf of California, Mexico29.0N 112.3W
The Sea of Cortez, also known as the Gulf of California, stretches diagonally across this image, separating the Baja California peninsula from mainland Mexico. The brown peaks of the Sierra Madre Occidental can be seen parallel to the coast on the mainland.
The two large islands in the gulf are Isla Ángel de la Guarda, also called Archangel Island, closer to the peninsula, and Tiburón Island, closer to the mainland.
Isla Ángel de la Guarda is a large island east of Bahía de los Ángeles, and separated from the Baja California Peninsula by the Canal de Ballenas (Whales Channel). It is the second largest of the eleven Midriff Islands or Islas Grandes. It is part of the state of Baja California.
Isla Tiburón (meaning Shark Island) is both the largest island in the Gulf of California and the largest island in Mexico, with an area of 464 sq mi (1,200 km2). Tiburón Island is part of the state of Sonora, as well as the municipality of Hermosillo, and is located at approximately the same latitude as the city of Hermosillo.
