Spider Hole November 2021

Saturday 28/03/2015

Pete, Nigel & Myself. A very late start due to Friday night’s fire call, so literally down to the end. 1m x 10mm hole drilled, 1m of 40gm retired and fired. Again, we had the interesting phenomenon of an initial chase of fumes followed by another lot 10 minutes later. Certainly, they felt they were driven by a draught. Maybe the second lot of fumes comes up through the boulders. Adrian.
