In reply to Trangia: ....there are quite a few stories around of people at altitude where mountain-bikes have started buzzing and glowing, axes have been surrounded by St Elmo's Fire and so on. I reckon some of these accounts need to be taken with a fair pinch of salt (note not questionning the interesting posts above, and recognise that being high in the MB Massif is a whole different ball game - have heard VERY WEIRD stuff from very grounded people in relation to the microclimate there). I've been in loads of storms (bernese oberland and valais) and while the noises have been impressive, should I feel deprived that I've never experienced anything weird? Just rather boringly followed advice of where to sit when on a rock face - see

note this says that throwing away metal gear is pointless. although I'm not sure I'd want two axes pointed skywards on my back during a storm....
and

which interestingly gives the stats.
there used to be a very good petzl info sheet with those stick-person diagrams showing where to shelter in a lightning storm - but God knows where I filed that.
I have read a sad account of a strike killing on an outcrop (Climbing no206, sept25 2001) without any warning at all.
