Geography
Zavodovski Island (56°18′S 27°34′W / 56.3°S 27.567°W / -56.3; -27.567) lies 350 kilometres (217 mi) southeast of South Georgia Island. It is the northernmost of the South Sandwich Islands and the nearest to South Georgia. The island is approximately 5 kilometres (3.1 miles) across with a peak elevation of 551 metres (1,808 feet) above sea level. The stratovolcano Mount Asphyxia dominates the western side of the island while the eastern half is a low-lying lava plain. Mount Asphyxia is believed to be active with fresh lava reported in 1830 and numerous indications of activity since. Approximately 50% of the island is composed of tephra. The island is home to around two million breeding chinstrap penguins, making it one of the world's largest penguin colonies.
Visokoi Island (56°42′S 27°12′W / 56.7°S 27.2°W / -56.7; -27.2), which lies to the southeast of Zavodovski, is 7.2 km (4.5 miles) long and 4.8 km (3 miles) wide, capped by Mount Hodson, a volcanic peak (1,005 m/3,297 ft). The peak is named after Sir Arnold Weinholt Hodson, a governor of the Falkland Islands. Visokoi means "high". The island's eastern tip, Point Irving, is named for the commander of a British exploratory and mapping expedition, John J. Irving. Cmdr. Irving is the father of British historian David Irving.
Leskov Island (56°40′S 28°10′W / 56.667°S 28.167°W / -56.667; -28.167) is located to the west of the main arc of the South Sandwich Islands and is less than 1.5 kilometres (0.9 mi) long, and lies 48 km (30 mi) west of Visokoi. It was named by Bellingshausen after the third lieutenant on the expedition ship Vostok. It is composed of andesitic rather than basaltic lava. The subduction zone forming the South Sandwich Trench lies to the east of the island arc.

Famous quotes containing the word geography:
“Where the heart is, there the muses, there the gods sojourn, and not in any geography of fame. Massachusetts, Connecticut River, and Boston Bay, you think paltry places, and the ear loves names of foreign and classic topography. But here we are; and, if we tarry a little, we may come to learn that here is best. See to it, only, that thyself is here;—and art and nature, hope and fate, friends, angels, and the Supreme Being, shall not absent from the chamber where thou sittest.”
—Ralph Waldo Emerson (1803–1882)
“At present cats have more purchasing power and influence than the poor of this planet. Accidents of geography and colonial history should no longer determine who gets the fish.”
—Derek Wall (b. 1965)
“Yet America is a poem in our eyes; its ample geography dazzles the imagination, and it will not wait long for metres.”
—Ralph Waldo Emerson (1803–1882)
