Historical note on the "previously purist Eldon territories" described in the introduction of the report: The Axbridge (inc. Roger Gullidge) were the first UK club caving in that area, which was a good few years prior to the Eldon.
Originally, a couple of Eldon members took it upon themselves to go to the region on numerous prospecting trips to get a better idea of the full potential of the area, with a view to it being a realistic proposition, logistically, for a larger team expedition.
Eventually, after the initial full team Eldon expedition, there was, with a few notable exceptions, something of a hiatus in getting people to commit to going out there again, or at least in a sizeable group.
At this point, Ade joined in with the original two Eldon members who had originally been to blame for doggedly returning to breaking new ground out there, in what was at the time, far more hostile conditions than is the case now.
Ade Pedley (Crewe/YSS) has been pushing new stuff in the area for many years, and I reckon his expeds out there must certainly be heading into double figures by now.
Over the years, the welcome assistance of cavers from other UK clubs has been required to allow some nominal degree of backup, should anything go pear-shaped whilst up in the mountains.
