Which archipelago has its highest point at Mount Belinda on Montagu Island?

The South Sandwich Islands have their highest point at Mount Belinda on Montagu Island.

Mount Belinda is a 1,370-metre stratovolcano, making it the highest peak in the South Sandwich Islands. Montagu is the largest island in the group and lies among the central islands, between Saunders and Bristol. The archipelago forms part of the British Overseas Territory of South Georgia and the South Sandwich Islands in the Scotia Sea.

Mount Belinda is also notable for its interaction with ice. After remaining inactive for many years, it erupted from 2001 to 2007, producing basaltic lava and melting parts of the island’s thick ice cover. In 2005, a lava flow extended roughly 3.5 kilometres from the summit toward the sea. The volcano is sometimes confused with Mount Michael, which has a persistent lava lake, but Mount Michael is on Saunders Island and is lower at about 990 metres.
