A 6000 year old submerged forest that reappears from time to time

Something strange is happening, this relatively old post of mine has gone viral today, I think because news of recent storms in Wales revealing the petrified forest on the coast has reached the USA and searches are sending people to my site, which I suppose is nice. So I thought I’d re-blog to make it even easier for everyone ๐Ÿ˜‰ Old news has become new news again….

Although it is rarely seen, the remnants of a past forested landscape, where there is now sea and beach, is a very interesting feature and teaches us about past sea level rise and our recent glacial history, and makes sense of some of the archaeological remains we find around our coastline in West Wales.

At the end of the last glaciation the sea level was much lower than it is today because so much water was still locked up in the ice sheets to the north of Britain.ย  As the climate warmed forests became established on land that had been tundra for thousands of years, and this forest extended far out beyond where sea level is today.ย  Gradually as temperatures rose, the sea ice to the south of the arctic circle melted and sea levels rose, submerging much of the coastal forests.

In some places this action was very rapidโ€ฆ

  1. It is a very interesting post with an intriguing topic. I loved reading it! Good that people are lead to a site with sound information about the remains of those ancient forests. ๐Ÿ™‚

    1. It’s very odd though that they are coming in such huge numbers, I’ve never seen anything like it! Apparently there’s a link to it on a news site in the US ๐Ÿ™‚
