Clipperton Rock

Clipperton Rock is a volcanic rock formation on Clipperton Island in the central Pacific Ocean, extending roughly 100 meters and rising about 29 meters above the surrounding waters. The structure displays multiple cavities and internal passages created through erosion over millions of years.

The rock is the remnant of an ancient volcanic structure that formed Clipperton Island before it transformed into a coral atoll. Its presence reveals the island's geological history and evolution from a volcanic to a coral system.

French scientists established a geodetic marker from the National Institute of Geographic Information on the rock surface for precise measurements.

Access to the formation is challenging, as the island is rarely visited and requires permission to reach. Visitors should prepare for unstable conditions and harsh environments when exploring the area.

Next to the rock sits Trou-sans-fond, a circular hole roughly 90 meters deep connected to a volcanic chimney system. This feature contains notably high concentrations of sulfur compounds that reflect its volcanic origins.
