Overview
Genovesa Island (Spanish: Isla Genovesa), also known as Tower Island, is a shield volcano in the Galápagos Islands in the eastern Pacific Ocean. The island occupies about 14 km2 (5 sq mi), and its maximum elevation is 64 m (210 ft). The horse-shoe shaped island has a volcanic caldera whose wall has collapsed, forming the Great Darwin Bay, surrounded by cliffs. The saltwater Lake Arcturus lies in the middle, and sediment within this crater lake is less than 6,000 years old. Although no historical eruptions are known from Genovesa, there are very young lava flows on the flanks of the volcano.
