The 22 km² Isla del Coco (Cocos Islands) is the subaerial portion of the Cocos Ridge, shown in this December 2019 Planet Labs satellite image monthly mosaic (N is at the top). A Pliocene-Pleistocene shield volcano partly forms the roughly 7-km-long (in the NE-SW direction) island. Steep cliffs around the coast expose thick columnar-jointed lava flows, thin lavas, and breccias (possibly debris flows).
