The main island is generally mountainous. The only flat area is on the north-west coast, which is the location of the only settlement, Edinburgh of the Seven Seas. The highest point is a volcano called Queen Mary's Peak 2,062 metres (6,765.1 ft), which is covered by snow in winter. The other islands of the group are uninhabited, except for a weather station with a staff of six on Gough Island, which has been operated by South Africa since 1956 (since 1963 at its present location at Transvaal Bay on the south-east coast).

Where is the weather station with a staff of 2,062 currently located?
