The first snow on the hills this winter has gone now but more is
forecast. On a walk on the Cairngorm Plateau last week before the snow went I wore
heavy duty microspikes (Hillsound Trail Crampons) as the snow was hard
and icy. I had an ice axe as well but didn’t use it – the snow was not deep
enough for it to be any use and trekking poles were better for balance. I
wouldn’t have left it at home though as I could have needed it if there’d been
any deep drifts to cross.
In fact, if there’s snow on the hills I always carry an ice axe
and crampons or microspikes. Both are important for safety. Which is best
depends on your activities. For hillwalkers with no aspirations for technical
winter climber the simplest ice axes and crampons or spikes designed for
walkers are fine, and that is what I’m writing about here.
Hillwalking on snow and ice is a
mountaineering discipline and needs extra skills. Being able to use an ice axe
and crampons correctly is a major part of this. Just carrying them does not
make you safe. Using an ice axe to protect yourself from slips and to stop
falls if they occur requires training and practice. Similarly, how to walk in
crampons and how to use them on different slopes whilst not difficult is not
something to try and learn high in the hills in a blizzard. A course at an
outdoor centre or with an instructor is the best way to learn.

ICE AXES
Ice axes
are rated CEN-B (basic)/UIAA Type 1 or CEN-T (technical)/UIAA Type 2. These
ratings are decided by several tests to assess the strength of the axe.
Unsurprisingly, CEN-T axes are stronger than CEN-B ones. Does this matter? Not
for hillwalking and general mountaineering. B rated axes are fine for these
activities and usually lighter and less expensive than T rated ones.
Picks
For
hillwalking axes usually have a slightly down curving pick (sometimes called a
classic curve), as this is good for self-arrest and for climbing steeper slopes
where you swing the pick into the snow. Up curved picks are for technical
climbing. A row of teeth under the pick helps it to grip.
Shaft
Until
recently straight shafts were the norm for walking axes, curved ones again
being the province of ice climbers. Now though some walking and general
mountaineering axes have curved shafts. When climbing steep terrain using the
pick above your head a curved shaft helps stop your knuckles bashing against
the snow or ice. There is an argument that curved shafts give more leverage for
self-arrest. I can’t say that I’ve noticed any significant difference when
trying different axes and for hillwalking I would say straight and curved
shafts are both fine. All axe shafts have a spike at the end for thrusting into
the snow and this is the feature that gets the most use when hillwalking.
Rubberised
coatings on shafts can make them warmer to hold and more secure to grip. These
should be slim, so they don’t impede thrusting the axe into the snow. Some axes
have indentations in the lower section for better grip.
Adze
The adze doesn’t
get much use compared to the pick and the spike. If you’ll be doing much
step-cutting – unlikely if you have crampons – or digging a snow shelter and
you don’t have a snow shovel then a wide adze is more effective than a narrow
one.
Material
Most ice
axes have aluminium shafts and steel heads. The very lightest have aluminium
heads. The latter are fine for occasional use and often used by ski tourers who
probably won’t use an axe from one day to the next. However, aluminium isn’t as
strong as steel and blunts more easily. For regular use a steel head is best.
Weight
Two other
important factors are weight and length. The lighter your ice axe the less
burden it is to carry. For hillwalking when the axe is held by the head almost
all the time low weight is fine. However, if you’ll be doing much step-cutting
or climbing using the pick then a light axe is more tiring to use.

Length
Length is
contentious. The trend in the UK (it’s not the same everywhere) is for short
50-55cm axes even for hillwalking. I prefer a much longer axe (60-70cms) as it
feels more secure on easy angled slopes where a slip could still be dangerous
as I don’t have to stoop to reach the snow with it, which feels particularly
unstable when going downhill. I also find it easier to thrust a long axe into
the snow to prevent a slip becoming a slide. Some say short axes are better for
self-arrest. Maybe if that’s what was used when learning. I learnt with a long
axe and am perfectly happy using one for self-arrest. I think an axe that
reaches the ankle or even almost to the ground is best for hillwalking.
Whatever
length or weight of axe you choose the most important factor is knowing how to
use it properly. No ice axe is much use if you don’t know what to do with it.
Leashes
Leashes
and wrist loops come with many axes and can be fitted to others. They mean that
if you drop the axe it doesn’t disappear down the hill. However, they also mean
that when changing direction you have to change the wrist loop from hand to hand,
which can seem a nuisance if you have to do it often.

My favourite ice axes. From the left: Camp Corsa (250g), an ultralight all aluminium 60cm axe I take when I don't expect to need an axe but just might (I once carried it coast to coast across Scotland on the Southern Upland Way in February and never used it once); Camp Nanotech Corsa (285 grams), same as the Corsa but with a steel tip to the pick and a steel spike, I use it when ski touring and backpacking; Grivel Helix (485g), a good 66cm general purpose axe with a plastic head cover for warmth and comfort that I take on day and overnight trips when I expect to use an axe; Petzl Glacier (410g), an alternative to the Helix, slightly lighter and slightly longer at 68cms. I can't decide which I like best.

CRAMPONS
On hard snow
rubber soles have little if any grip. It can be difficult to stay upright on
the flat, let alone on a slope. Sheet ice is even more slippery. Put metal
spikes on your boots and suddenly that slipperiness vanishes and hazardous
terrain becomes easy and safe. Even after decades of wearing crampons every
winter the first time I put them on in the autumn I’m still amazed at the
difference they make. If there’s snow on the hills I don’t go without them. In fact,
I reckon I use crampons or micro spikes more than an ice axe, as often there’s not
enough snow for an axe to be any use but enough ice to make walking tricky and
even dangerous. On one occasion I wore crampons the whole way to Ben Macdui and
back without taking my ice axe off my pack as the whole Cairngorm Plateau was a
sheet of ice.

Footwear
Rigid
mountaineering boots are usually recommended for winter hillwalking. If you’ll
be doing anything approaching technical climbing then they are a good idea. I don’t
think they’re necessary otherwise. Boots that have some forward flex are easier
to walk in and less tiring on the feet. Many walking and general mountaineering
boots will fit these. Indeed, some will fit just about any outdoor footwear,
including trail shoes. I prefer boots though because I don’t like cold, wet
feet and they allow me to kick steps if I’m not wearing crampons.
Whatever
footwear you choose it’s important that your crampons fit them properly and
that you know how to put them on securely. Practising this at home is a good
idea. Trying to figure out the strapping system with cold fingers as a blizzard
closes in is not a good idea. Crampons aren’t all the same shape,
and neither are boot soles, so they need to be compatible. Checking the fit in
the store when you buy new crampons or boots is the best way to do this. A
properly fitted crampon shouldn’t come off when you hold it upside down with
the boot attached and the straps undone and shake it.
Types of Crampons and Micro Spikes
Tiny
spikes linked by chains and attached to footwear by stretchy harnesses are the
simplest form of crampons. Often called microspikes they work okay on level and
gently sloping ground and they are excellent on icy paths. The short spikes don’t
grip as well as the longer ones found on full crampons but are easier for
balance when the ice is thin. Once slopes begin to steepen microspikes become less
effective and awkward to use. I carry them when I don’t expect to encounter
much snow or ice but there might be the occasional patch I have to cross. Sometimes
conditions mean I wear them for longer, as I did a week before writing this,
when I put them on to cross an icy snow slope on the Cairngorm Plateau and then
kept them on for the descent as they made walking so much more secure. The snow
and ice cover was thin though.
Full crampons
attach more firmly to boots and have longer points. They may
be rigid or flexible. The first are designed for rigid boots and technical
climbing and aren’t suitable for use with walking boots. Flexible crampons are
made of two sections linked by a bar and can be used with flexible boots. These
are known as general mountaineering, trekking, or walking crampons. The flexible
linking bars come in different degrees of stiffness. With some crampons you have
the option of more or less flexible ones.
Crampons
usually have ten or twelve points though ice climbing ones may have more and
simple walkers’ ones less (and some micro spikes more – I have ones with 18
points). Ones with points that angle outwards from the front (called front
points) are useful for climbing steep slopes when you can just stick them in
the snow for grip. Points should be spread out along the boot sole for maximum
grip. The length
of points is not a major consideration, but shorter ones are more stable when
walking on rocks or bare ground, something often done in the British hills when
the snow and ice is patchy.

Materials
Most crampons are made from heat
treated steel as this is hard wearing and the points stay sharp for a long time
and can be easily sharpened. The lightest crampons are made from aluminium.
These don’t stay sharp very long and aren’t as tough as steel ones. However,
they are fine for most walking use.
Attachments
There
are various ways of attaching crampons. Plastic cradles that mould
round the heel and toe of a boot and are then held in place by a single strap
can be used with flexible boots and are quite easy to fit. Clip bindings with a
heel lever and a front bail, usually linked with a strap, are even easier to attach
but will only fit boots with a pronounced welt at the toe and heel. They are
also best used with rigid boots as they can spring off flexible ones. Some
crampons come with heel levers and front cradles, a good compromise.
Balling Up
Soft
snow can stick to crampons, leading to large clumps building up underneath
them. This is known as balling up and makes walking uncomfortable and can be
hazardous. The traditional way to get rid of this snow is to tap the side of
the crampons with your ice axe. This works but may need to be done frequently.
It can also be awkward on steep slopes when you need your axe for safety and
balance. Much safer and more efficient are anti-ball plates, usually made of
rubber or plastic, which fit underneath the crampons. All crampon makers offer these,
and an increasing number are supplying them as standard.
