Travertine Dams and a lovely coincidence

Steve and El have been filming in the Forest of Dean, helping to build a case for the Forest to be designated a UNESCO Biosphere, in recognition of its unique landscape and biodiversity. If successful, this will hopefully form a catalyst for organisations to work together in protecting this rich heritage from the ravages of over-commercialisation and over-extraction of precious resources.

Steve and El were lodging for a few nights with my good friend Bridget and mentioned their interest in the Travertine Dams of Slade Brook, and in particular a post written about the dams in a blog called About Angie. “I know Angie!” says Bridget.

Now how's that for an amazing coincidence? After an excited phone call from Bridget, it was settled;  I would take Steve and El to film the dams.

A little bit of science... Travertine Dams are formed when underground water absorbs limestone from the rocks through which it flows. When this water springs to the surface it inevitably splashes over stones and fallen twigs, causing carbon dioxide to be released and the limestone to come out of solution and be deposited on the obstructions. In time these deposits grow to form small dams and waterfalls. The Travertine Dams of Slade Brook are among the best in the world and are already a Site of Special Scientific Interest (SSSI) – truly a jewel of the Forest of Dean.

As we made our way to St Briavels, I learned that I wasn't just going to be navigator and guide for the day.  

"Are you willing to be recorded?" they asked. 

"That's fine," said I, "so long as you don't ask me any awkward questions."

"Okay, Angie.  What gave you the idea of writing a blog?"  That was easy – a move from Corwall eight years ago and a whole new forest to explore, together with the glorious Wye Valley and the distant hills of Wales.

How were these Travertine Dams formed?"  I knew the answer to that one (see above) and did my best to explain it 'live'.  This girl was on a roll. "Next question, please."

"What can you tell me about the dangers to the ecology and environment of the Forest of Dean?"

"Um... errr..."

In truth, though, it all went pretty smoothly and I was treated to an hour or so of watching a couple of professionals at work.

 

 

Not only is El a skilled sound recordist, but she's also an accomplished acrobat – a talent that Steve was keen to make use of in his film.  Exactly how acrobatics relate to UNESCO biospheres, I know not, but I've been promised a 'pre-release' look at the film we worked on and feel sure that it will be brilliant. 

Finally, acrobat El and guide Angie posed for a selfie.
