Rob G said:Without starting to argue about semantics and pedantry, I would be
interested in your thoughts on how an axe "prevents slips occurring in
the first place" in a walking situation.
if it's the sort of ground where you're walking without using your hands
at all then it's a fair point, but OTOH that's not usually the sort of
place you'll be taking off, and where a pole will actively prevent a
slip to start with.
Quoted message said:thinking of a "slide", then I would agree with you but what I am
meaning is the initial situation where the footing goes and you fall
into the slope and, if the axe has been placed properly, any further
movement down the slope is arrested. I cannot see how the axe
prevents such a slip (loss of footing) in the first place.
By being a point of direct support, so you don't fall.
Quoted message said:Does your website on walking poles include any guidance on how to use
them as a brake?. The mind boggles as to how this can be done.
It doesn't, but the answer is the same way as with an axe.
Quoted message said:has attached to each wrist a thin aluminium tube which is 1000 to
1200mm long (compare with one sturdy ice axe 550mm long attached
possibly by a long trace) and you have to manouevre these flailing
shafts as you fall such that presumably you can get a hand, with the
other pole attached to it, near the bottom of the other so the
leverage is minimal, and drive it into the snow. That would strike me
as difficult in the extreme unless extensively practiced and that is
not what most of us can do nowadays with so little snow.
It's bloody awkward, but the two times I've done it in anger were with
no prior practice aside from with an axe. I was sliding down slopes and
not slowing down, I had poles in my hands and I set to work using them
to arrest my slide. It worked on both occasions.
Quoted message said:What does worry me is that this is being stated as an effective
procedure
For some values of "effective". There is, as I previously suggested, a
spectrum of safety with steep water ice impossible to stop on with
anything at one end ground either flat or fluffy enough at the other
that you couldn't slide down it if you wanted to. Somewhere between
those two extremes are a place where a pole becomes useless and an axe
will work, and the steeper and slippier it is, the more the axe will be
important.
Quoted message said:in a thread about buying an ice axe by, one assumes, someone
who doesn't have an axe and is unfamiliar with walking on snow, and
could well take the comment from a regular contributor to this forum
as being acceptable practice. I would put it that the use of a walking
pole as a safety device when snow walking is not acceptable practice
and is would be dangerous to say the least if attempted by someone
without as much experience as Peter . I've got 45 years winter
experience and I would not like to attempt to stop myself with a
walking pole.
Did lots of snow walking in Norway back in July, we didn't have axes
with us, nor did anyone else we met. Quite a few poles in evidence
though. Lots of skiing is done without axes on steep snow, and no
shortage of people slipping and falling doing that, so how come that's
"not acceptable practice"?
Never have I said that a pole is a substitute for an axe, simply that on
more benign ground it is adequate, and being an intrinsically better
walking stick is actually /better/ on benign ground where a slip is
unlikely to lead anywhere except a cold backside.
A pole is considerably less effective on steep ground where you are
wanting to use your hands to help support you.
Quoted message said:It may well be considered that any advise given on usernet forums is
given freely, without prejudice and with the attitude that is up to
the receiver to use his judgement as to whether it is acceptable
advise or not. I don't think this is realistic as the OP wouldn't be
asking for advise if he didn't mean to act upon it. We therefore have
a "Duty of Care" to anyone who would use any advise we give to ensure
that it does not put them in a situation which is dangerous.
Which is why I specifically suggested an axe to him, probably 60-65cm
would be okay and to make sure he got practice at using it. I would
also suggest poles in benign territory where you won't be going anywhere
as they take a lot of the fatigue away from post holing, and fatigue is
one thing that's led to many accidents over the years. If in doubt,
have the axe in your hand rather than a pole, but there's plenty of
places where there's no doubt you won't go anywhere. "Snow walking"
covers a lot of ground.
