It is about 6.5 km (4.0 mi) long and 5 km (3.1 mi) wide and rises to 288 m (945 ft) above sea level. Much of the island is permanently covered with ice. The average temperature range is 0 °C (32 °F) to about −10 °C (14 °F) in winter (i.e., in July). The extremes reach about 12 and -44 °C (53.6 and -47.2 °F).
The British Antarctic Survey maintains the Signy Research Station, a scientific station for research in biology. The base was opened on March 18, 1947, on the site of an earlier whaling station that had existed there in the 1920s. The station was staffed year-round until 1996; since that year it has been occupied only from November to April. It houses 10 people.

Famous quotes containing the word geography:
“The California fever is not likely to take us off.... There is neither romance nor glory in digging for gold after the manner of the pictures in the geography of diamond washing in Brazil.”
—Rutherford Birchard Hayes (1822–1893)
“Ktaadn, near which we were to pass the next day, is said to mean “Highest Land.” So much geography is there in their names.”
—Henry David Thoreau (1817–1862)
“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)
