The British Caving Association

The Overground Underground Festival in Ingleton runs from the 25th to the 31st May in the Dales. The program is available on: http://www.ogug.co.uk. There are many interesting talks and activities. I will talk on sat 25th at 2pm, about the information that caves hold on the ancient history of the earth and will show Sid Perou's film made from the archive and entitled The Birth of a Yorkshire River. This is made from film shot in 1954 by Eli Simpson.
