==Geology==
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 5,600 feet or 1,707 meters), lie directly on the equator. The island is primarily noted for its geology, providing excellent examples of a geologic occurrence that created the Galapagos 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.
