Isabela Island, Isabela

#3 of 12 in Nature in Isabela
Isabela Island is the largest island of the Galápagos with an area of 4640km2 and length of 100km almost four times larger than Santa Cruz, the second largest of the archipelago. It was named after Queen Isabella of Spain. It was originally named Albemarle after the Duke of Albemarle. The island strides the equator.
One of the youngest islands, Isabela is located on the western edge of the archipelago near the Galápagos hotspot. At approximately 1 million years old, the island was formed by the merger of 6 shield volcanoes - Alcedo, Cerro Azul, Darwin, Ecuador, Sierra Negra, and Wolf. All of these volcanoes except Ecuador are still active, making it one of the most volcanically active places on earth. Two of the volcanoes, Volcan Ecuador and Volcan Wolf (the island's highest point with an elevation of 1707m), lie directly on the equator. The island is primarily noted for its geology, providing excellent examples of a geologic occurrence that created the Galápagos Islands including uplifts at Urvina Bay and the Bolivar Channel, tuff cones at Tagus Cove, and Pulmace on Alcedo and Sierra Negra, one of the most active volcanoes in the world.
