Supply Reef
From Wikipedia, the free encyclopedia
Supply Reef is a name for a submerged circular reef (300 feet in diameter) of volcanic origin in the Northern Marianas Island chain that is 10km NW of the Maug Islands. Presently this igneous seamount is roughly 27 feet below the ocean's surface. It is uncertain whether the volcano is extinct or dormant (there is living coral on the rim of the volcano's crater). The exact location of Supply Reef is 20.13N and 145.10E.
