Please note this report from Ieuan Starks of School Camp regarding climbing at Morlais Quarry:

"A large rock was dislodged by my group and would have caused sever injury if it had hit someone.  There appears to be a line of loose rock 3/4 of the way up the corner climb but on the flat wall (I have not managed to abseiled in to inspect this).  Please see photo attached for area marked in red.  NB. This is not the abseil wall, but the next corner along (60m south) identifiable by a small tree above the flat wall."
