The event, a celebration of the Scottish island's Norse heritage, drew massive crowds with many 'warriors' wearing winged helmets and sheepskins.

UNSW scientists have shown -- for the first time -- that a series of high-profile burial sites in the Pacific, Mediterranean and northern Scotland were likely related to catastrophic tsunamis... Honorary Professor James Goff from the PANGEA Research Centre at UNSW Sydney, who co-authored the paper, says the research provides new insights into past human-environment interactions and a new perspective on past catastrophic events... The researchers looked at coastal mass burial sites in the Solomon Islands and Vanuatu as well as in Orkney and Shetland. The mass graves cover a long timeframe of human history -- they are from about...

An ancient Shetland settlement at risk of crumbling into the sea has been rebuilt - despite fears that it will soon be eroded. The work on the burial site in Sandwick Bay, Unst, follows an excavation led by the Scottish Coastal Archaeology and the Problems of Erosion Trust (Scape). It teamed up with the Council for Scottish Archaeology's Adopt-a-Monument scheme for the rebuild project. The new structures will allow visitors to see the excavation findings. It is thought that the structures may only last a couple of years, due to coastal erosion. Local groups, working with archaeologists and ancient building...

Buried deep beneath the sediment of the North Atlantic Ocean lies an ancient, lost landscape with furrows cut by rivers and peaks that once belonged to mountains. Geologists recently discovered this roughly 56-million-year-old landscape using data gathered for oil companies. "It looks for all the world like a map of a bit of a country onshore," said Nicky White, the senior researcher. "It is like an ancient fossil landscape preserved 2 kilometers (1.2 miles) beneath the seabed." So far, the data have revealed a landscape about 3,861 square miles (10,000 square km) west of the Orkney-Shetland Islands that stretched above...
