Slaley Sough

At the February meeting of the DCA in Monyash, shortly after discussing the air in Slaley Sough with Mike Higgins, I was asked by Adam Russell if I could take a trip in there some time, and sample the air in Thunder Shaft, a 151ft deep winze which lies just off the main cartgate in the Flixen Rake section of Slaley Sough. Getting information about Slaley Sough isn't easy. The description of the approach in Caves of the Peak District is vague, and a six-figure grid reference doesn't help much in the thorny jungles that cling to the high slopes of Via Gellia!
