Many thanks to those who fixed the problem !
This means you can now have a look at the latest offering on the BCRA Online Archives:
BCRA/201D/I, Northern Midlands Group Peak Cavern Reports: 1948-1961
Well worth a look for Les Salmon's reporting of the work he and his collegues did in Peak during that time; meticulously written up in detail with sketch surveys of the new discoveries they made. Plus the correspondence between Les and Eli Simpson. Many thanks to Wayne Sheldon & TSG for making this available for digitising and to Langcliffe who did all the work and has made it available for all to enjoy.
