My French friend, Jean-Francois, called today to ask if I enjoyed the video of Verna. Of course, I told him. Several cavers have also commented on it, but how was it lighted? He responded that he assumed the photography team used the existing lighting. When I asked him what the hell he was talking about he said maybe he had forgotten to tell me that Verna was semi-commercialized two years ago! Go figure.
Anyhow, here is the web site:
http://www.laverna.fr/ and I suspect Google or altavista.com can translate the page for you.
They have also succeeded in building a dam in the river in the cave and piping the water out and down the mountain to a hydro-electric plant in St. Engrace. This is what they tried to do back in the 60s when the EDF Tunnel was first made.
On google-earth go to:
Arette Pierre St Martin, 64570 Arette, France
Kakoueta Groge and St Engrace are just west of this.
