Nine Pin Islands Field Trip

Dr R Shaw & Professor B Owen
Saturday, 17 Oct 2009
The Nine Pin Islands are probably the most spectacular development of columnar hexagonal jointing in tuffs in the world, and are reminiscent of the world heritage site of Giant's Causeway in Northern Ireland.

We are delighted to welcome Professor Bernie Owen and Dr Raynor Shaw to lead another boat excursion to the beautiful and inaccessible Nine Pin Islands. This is to be followed by a visit to the Ming dynasty Tung Lung Fort, designed to defend the coast from pirate attacks, then optional swimming in a remote bay.

The Nine Pin Islands are probably the most spectacular development of columnar hexagonal jointing in tuffs in the world, and are reminiscent of the world heritage site of Giant's Causeway in Northern Ireland.

The tuffs of the islands were erupted about 140 million years ago, a time when dinosaurs roamed the world. It is estimated that approximately 70 cubic kms of rubble were erupted during the single event which formed the tuffs. This compares with only 2 cubic kms for the Mt. St. Helens eruption and 12 cubic kms for the Krakatau eruption of 1883, which dispersed haze all over the world.

The boat trip, through attractive scenery and then open seas to the islands, takes about one hour. First we plan to visit the North Nine Pin Island to see and walk over the beautifully developed hexagonal columns, some of which have toppled over above a large rock slide. The second stop will be on the South Nine Pin Island at a sea arch developed along a fault. The trip also includes a circumnavigation of the islands to view the spectacular cliff scenery.

This is to be followed by a visit to the Ming dynasty Tung Lung Fort, designed to defend the coast from pirate attacks, which is set is spectacular scenery. On the return journey, a stop is planned at a remote beach for relaxation. A full lunch is also to be served aboard the boat.
