South Georgia and the South Sandwich Islands are a collection of islands in the South Atlantic Ocean. Most of the islands, rising steeply from the sea, are rugged and mountainous. At higher elevations, the islands are permanently covered with ice and snow.

The South Sandwich Islands comprise 11 mostly volcanic islands (excluding tiny satellite islands and offshore rocks), with some active volcanoes.

Captain James Cook discovered the southern eight islands of the Sandwich Islands Group in 1775, although he lumped the southernmost three together, and their status as separate islands was not established until 1820 by Fabian Gottlieb von Bellingshausen. James Cook was born in 1728, in Yorkshire, England. He sailed the seaways and coasts of Canada (1759 and 1763–67) and conducted three expeditions to the Pacific Ocean (1768–71, 1772–75, and1776–79), ranging from the Antarctic ice fields to the Bering Strait and from the coasts of North America to Australia and New Zealand.

The northern three islands were discovered by Bellingshausen in 1819. The islands were tentatively named "Sandwich Land" by Cook, although he also commented that they might be a group of islands rather than a single body of land. Fabian Gottlieb von Bellingshausen was a Russian explorer who led the second expedition to circumnavigate Antarctica (1819–21) and for whom was named the Bellingshausen Sea, an area of the Antarctic waters.
