Back to the Eli Simpson film rushes page: In 1953 The British Speleological Association initiated a project under the leadership of Eli Simpson to make a 16 mm film about limestone caves in the Yorkshire Dales called "Birth of a Yorkshire River". They had a number of sessions filming both on the surface and underground, experimenting with both monochrome and Kodachrome film. The project was eventually abandoned, but the rushes were discovered in the Eli Simpson Archive held by the BCRA. This set of monchrome rushes show a male caver in shorts and without a helmet, and two ladies moving around in Gatekirk Cave. At 01:10s in, the large lighting unit can be seen.
