In reply to Oceanrower:
Actually, my understanding is that much of the woodland is self-seeded and has been allowed to get out of control. It needs thinning drastically. Maybe the trees at the top of the isolated buttress could be removed at the same time as the bolts to stop people belaying from them.
Paths. Right. Yes it has paths. A bridge between the pinnacles on Crib Goch would go down well, after all Snowdonia has paths too.
A levelled base. You mean the matting? Again, right. To try and preserve things but is largely unnoticeable if maintained. A whole other level to replacing a whole boulder with concrete or a bridge.
The railway, that is at the bottom of the valley and has no impact on the rocks.
I will re-iterate my point and leave it at that, I think it's made and there's no point repeating myself. If a large part of the buttress has fallen off, then instead of replacing it with intrusive, man made structures of concrete, we should consider why it has fallen off in the first place. Lets think about how we can climb here, without damaging the place for everyone else.
If people can't be trusted to use ropes safely, hack all the trees back at the top and take all the bolts out. Make it a bouldering venue.
