Bonza's Blocked

After seeing a thread on UKC Regarding Lost world and access to Bonza crack I took a trip up to see what the fuss was about, See exactly how blocked / shored up it was etc.

Here's the tunnel

What I found inside...
Basically it aint how I left it last time I was here! a slight collape from the roof before the tunnel mouth means although light still comes through and a wriggler could wriggle, they'd likely be squashed like a bug. Here's a shot I took before the fall from outside:
And here is yesterday:
You'll notice the outer skin is unchanged, however the floor of the tunnel is definitely raisedand the block on the left behind the outer skin has dropped down. I'd guess that although you could abseil in to start it, while the move may be the same, the stability of the outer skin might be questionable on a macro scale.

Coincidently, a diagonal fault on the wall between Harold Void and the ladders has got a couple of inches wider too. If there is a big freeze this winter I expect there will be some geology in action!

Unlike most Guidebooks, Llanberis Slate suffers not only from New router's putting it out of date, but the actions of the quarry itself. (Nant Peris quarry lost 90% of its routes to rockfall while the guide was at the printers)
