Cortes Bank, Ocean bank in Los Angeles County, United States
Cortes Bank is an underwater bank off the California coast that rises steeply from the deep ocean floor with formations of sandstone and basalt. The shallow summit named Bishop Rock reaches within just a few feet of the water surface.
The bank was once an island that sank beneath the waves around 10,000 years ago at the end of the last ice age. This geological shift left behind a remarkable underwater feature that continues to shape maritime activity today.
Marine researchers and scientists regularly visit this location to study its extensive kelp forests and document the diverse underwater ecosystem.
The site is difficult to access and demands experienced mariners with specialized equipment for safe navigation. Visitors should know that conditions here change quickly and strong currents are common.
The location is famous for its giant waves that form when deep ocean swells collide with the shallow reef structure. This makes it legendary among extreme surfers seeking the most challenging conditions.
