Old Artificial Island Found in UK Lake

Archaeologists used new techniques to learn about an old artificial island in a Scottish lake that is older than Stonehenge.

The island in Loch Bhorgastail looks like it is made of stone, but researchers found that wood was used to build it.

People knew there was some wood under the island, but they did not know how much until they dug and analyzed it.

When archaeologists worked on the island, they found wood and brush under the stone and many old pots in the water.

Dr Stephanie Blankshein said that when they started digging, they found a big wooden structure under the stone island, which was a surprise.

When archaeologists worked on the island, they found wood and brush under the stone and many old pots in the water.

Dr Stephanie Blankshein said that when they started digging, they found a big wooden structure under the stone island, which was a surprise.

Before digging, they did not know what was under the island, just that there were pieces of wood.

Researchers used a special technique to make 3D pictures of the island above and below the water.

Dr Blankshein said that they learned the island was made of wood, not just stone with some wood underneath.

They did a lot of work and found that the island was built around 3500 to 3300 BC, like other sites in the area.

Crannogs are old artificial islands, and there are many in Scotland's lakes.

Dr Blankshein said that the islands were built by complex communities and are very important.

Archaeologists worked on the site for several years, using old and new methods to learn about the island.

They found that the island was first built over 5,000 years ago as a wooden platform.

Later, more brushwood and stone were added, and there was more activity during the Iron Age.

A stone path under the water connects the island to the shore, and the site was first found in 2009.

Experts used photogrammetry to learn more about the island, taking many pictures from different angles.

Taking pictures in shallow water is hard, so the archaeologists made a new technique.

Professor Fraser Sturt said that shallow water makes it hard to take good pictures.

Photogrammetry works well in deep water but not in shallow water.

The researchers used special cameras that can take good pictures in low light.

The cameras were fixed on a frame to take overlapping pictures.

A diver moved the cameras through the water, controlling their position very accurately.

The researchers wrote about their method in a new article.
