The HMS Viscount Melbourne was a three-mast, 800-ton sailing wooden ship which ultimately struck a reef in the Laconia Shoals, a large reef complex off the shores of Miri. The wreck lies about 40 meters deep beneath the surface.
The Great Cave of Niah is enormous by any measure. The floor area of the cave has been calculated at almost 10 hectares and in places the cave roof rises a majestic 75 meters above the rubble-strewn floor. It has been the site of around 40,000 years of human occupation.
