Log in to snowHeads to make it MUCH better!
Registration's totally free, of course, and makes snowHeads easier to use and to understand, gives better searching, filtering etc. as well as access to 'members only' forums, discounts and deals that U don't even know exist as a 'guest' user. (btw. 50,000+ snowHeads already know all this, making snowHeads the biggest, most active community of snow-heads in the UK, so you'll be in good company)..... When you register, you get our free weekly(-ish) snow report by email. It's rather good and not made up by tourist offices (or people that love the tourist office and want to marry it either)... We don't share your email address with anyone and we never send out any of those cheesy 'message from our partners' emails either. Anyway, snowHeads really is MUCH better when you're logged in - not least because you get to post your own messages complaining about things that annoy you like perhaps this banner which, incidentally, disappears when you log in :-)

New research into the process that triggers slab avalanches may be used to help predict danger on the slopes.
The Edinburgh University study has contradicted the theory that steeper slopes are more dangerous.

interesting stuff - i wonder if the study is available online?
Well, the person's real but it's just a made up name, see?

BBCs explanation is bit simple.
The paper summary is here...
Will read the full pdf later
(lots of hard maths).
I *think* the paper suggests that the trigger mechanism for slab slides doesn't relate directly to slope angle ?
However once a slide has triggered then gravity kicks in...

what theory? The general rule is that anything above 25 degrees is prone is likely to slide (the key being likely).
They should use Google, their theory sounds like this:-
http://pistehors.com/backcountry/wiki/Avalanches/Slab-Avalanches
> A slab avalanche is a large, moving area of snow which can be as big as 300 sq m.
yeah right, the staunchwall can be 1-2km long in the biggest avalanche, 300sq.m is a 100x30m slab which is small.
Anyway, snowHeads is much more fun if you do.

I also wonder where they got there research from. Having studied in the Swiss avalanche centre and experienced a number of situations, no matter what anyone says about this, avalanche study is not a very exact science no matter what fancy maths or science gear you have available. Nature is the master and must be respected just like at sea. I have seen very small slap avalanches of only a few metres and also some covering many hundreds, it all depends on the conditions of the day in question. Even a slope of 15 - 20 degrees can slide in the right conditions.
