a random one
was talking to a colleague at school today - (a geologist and climber) - and we were pondering what marble is like to climb on...
anyone done any?
Nib's - there's loads in northern italy - any experience?

not sure what its geology is but I spent a bit of time at a place in leicestershire called 'beacon hill' as a nipper - really slippery marble like-rock and great for technique (like climbing on slate but more shapely features)

My alcohol soaked brain screams "Beacon Hill Hornstones" for some reason.  Precambrian sedimentary, anyone?

there's one small crag close to siena, where we all grew up climbing wise, and it has a thin limestone surface over marble (it was an old quarry).
it's shit.

Used to be some quarry in France ,I think, where a whole load of photos came from of some clean cut angular rock in the early 90s. One route called Etoile Noir? Was that marble?

Marble is metamorphosed limestones/chalks. I'm not sure to what degree of metamorphosis or if it's contact or regional, but that's not important. I reckon it'd be very slippery when wet to climb, and would polish easily, so kinda like limestone but a bit slipperier (if that's a word.)

And it only took 2 and a bit months to think up that witty repose.  Well done.
