As both Chris and Richard have stated this crosscut has always been prone to falls.
However the quantity of material falling has increased considerably over the years!
Initially, where you dig, an arch could be seen, in the floor!
When we were through, with West Cumberland, this arch could no longer be seen.
Dave Banks wrote the whole thing up, including the connection to Capelcleugh.
However I feel there is still exploration to be carried out here!
