Nightingale Island
Named by the British Captain Gamaliel Nightingale
in 1760, Nightingale is the oldest of the three main islands of the Nightingale
Group, with recorded volcanic rocks from 18 million years to 360,000 years old.
The island group is only a small remnant of a much larger active cone. The main
island is only 2.5 x 1.5 kms and has an area of about 3.2 km2. Its highest
point, High Peak, is about 370 metres (1200 ft) high.
