Nothing to do with blasting in Ball Eye quarry then? Clatterway Levels are only 150m away from the edge of the quarry and there's a drilling rig up the top end. Very rough plot of Clatterway Levels, top entrance passages not shown.

There's an annual glow worm survey carried out in the Peak and surrounding areas. Guaranteed to see some if you volunteer, the only down-side is that they start glowing at pub o'clock.

MicroTraxion and other bits found near Hell's Well. Left in- situ but clipped onto first p-bolt on left, so it's out of sight. I can recover this on Thursday and deposit at the Mining Museum if required.

Sign spotted on Salters Lane...

Yep, found another on the second pitch of the through-trip.  Will soon have found enough to rig Oxlow, just need some rope...

Krab found in hanger at head of climb down to lower series. Nuff said.

Found: One Krab in P8 below Idiot's Leap. I've got some like it already and think they're crap, so please somebody, either claim it if it's yours, or just guess the colour of the tape if anyone fancies lucky dip.

Subject line says it all really, but here goes... Found, one short sewn tape sling, Old Gell's Mine in Via Gellia. Nuff said.
