Great Sound

Other geologists dispute the origin of the Bermuda Pedestal as a volcanic hotspot.

[2] The Great Sound dominates the southwest of the island chain and forms a natural harbour.

It is surrounded on all sides by islands, except for the northeast, where it is open to the Atlantic Ocean.

[1] In the east, the Great Sound narrows to form Hamilton Harbour.

During the Second World War Great Sound was the location several military installations: The United States Navy's Naval Operating Base, the Royal Naval Dockyard, on Ireland Island, RAF Darrell's Island, and Royal Naval Air Station Bermuda, on Boaz island.
