I've recently encountered a loose chunk of rock in the wall of the Giants upper traverse (Roughly the size of a large brick, right hand wall, about head height, just after the Windpipe.) I tried to give it a garden but while it's wiggling about in the wall pretty freely, for now it won't actually come out. Could maybe use a visit from someone with a crowbar, but otherwise just beware as it's in the right place to be seemingly attractive as a handhold (that's how I found it)

Thanks for the heads up, I'll bring my superglue next week!
