Redonda Rock[a] (Spanish: Roca Redonda, "Round Rock") is a flat-topped, steep-sided islet located roughly 25 km (16 mi) northwest of the island of Isabela in Ecuador's Galápagos Islands. Redonda measures 100 m (330 ft) long and 50 m (160 ft) wide with a maximum elevation of 67 m (220 ft).[3] Its isolation and inaccessibility coupled with its rocky cliffs riddled with crevices and crossed by ledges has made Redonda a haven for nesting seabirds.[4]
This small volcanic island is the remains of a large shield volcano that has vastly eroded away below sea level. Potassium–argon dating of Redonda indicates that the islet is at least 53,000 years old.[3] However, it remains unknown when the last eruption occurred from the shield volcano. Several shallow submarine fumaroles exist around the island and may indicate that the volcano is still active.[5] Herman Melville described the rock in detail in his short story The Encantadas.
