Clouds partially obscure the 22 km2 Isla del Coco (Cocos Island) in this NASA International Space Station image. Chathan Bay (top) lies off the NE tip of the island, which sits astride the Cocos Ridge about 650 km SW of the Costa Rican port of Puntarenas. The rain-drenched island is renowned as the site of treasures buried by pirates and ship captains. Construction of a Pliocene-Pleistocene shield volcano was followed by caldera formation and the emplacement of a trachytic lava dome.
