The Boiler

Socorro Islands · Mexico

A submerged volcanic pinnacle off the northwest side of San Benedicto Island, rising from roughly 40m to within about 6m of the surface. Named for the way swell breaks over its two 'horns' and makes the water appear to boil, the site functions as a giant manta cleaning station where Mobula birostris are tended by clarion angelfish and routinely engage divers at close range. Bottlenose dolphins, multiple shark species and the occasional humpback whale song round out a small, circumnavigable seamount that can be looped twice in a single dive.
