The light-colored pyramidal island at the left is a small island of trachytic rocks between Bahia Wafer and Bahia Chathan, on the NE side of Cocos Island. The plug-like islet lies north of a massive lava dome lying between the two bays and consisting of flow-banded benmoreitic, trachytic, and quartz trachytic rocks.
