With winter well on the way with shorter hours of daylight, colder temperatures and the first snow on the hills outdoor organisations have been giving out advice on how hillwalkers should prepare themselves for more severe conditions, as they do every year at this time. With that in mind here's a piece, slightly edited, that I wrote for The Great Outdoors over a decade ago that is still relevant.
"Snow
showers, some heavy. Windspeed at 3000 feet: 35mph, gusts to 50mph. Cloud base:
2,000 feet, falling to 1,000 feet in showers. Visibility: poor in showers.
Freezing level 500 feet. Temperature at 3,000 feet: -5 Celsius. Hazards: severe
wind chill".
Such
was the mountain forecast when I sat down to write this piece in early December
over a decade ago. Those familiar with the hills in winter will be able to
picture what it means - spindrift blasting across the ground as you stagger
along, head down, hood up, leaning on your ice axe in the worst gusts as you
try and keep your feet. The sky and ground merge into a whirling white cloud
that makes navigation very difficult. Any bare skin is instantly chilled by the
driving wind. Ice forms on eyebrows, hair, jacket hood. Fingers freeze quickly when
you remove your thick mitts to handle maps, unzip pockets, unwrap snack bars.
Stopping for more than a few minutes leaves you numb with cold. And all the
time the wind roars round you, making it difficult to think.
When
I know the weather is going to be like that I plan accordingly, choosing a
lower route than I would in better conditions or even deciding to stay in the
shelter of the woods. Often though the weather can change quickly when you are
already high in the hills and you end up finishing your walk in a blizzard.
Mostly this is no more than cold and unpleasant. Sometimes it can be
exhilarating and strangely exciting despite the discomfort. What happens though
if something goes wrong? You get lost, someone is injured or becomes exhausted,
the walk takes longer than expected due to the weather and the sun sets with
you still far from safety.
Surviving
a night out or a long delay in winter depends
to a great extent on the equipment you are carrying. The ability to use
that equipment properly is of course important but you have to have the
equipment in the first place. Winter hillwalkers mostly all carry ice axes and
crampons, extra warm clothing, hat and gloves, torch, plastic survival bag and
food and drink in winter. Here I am going to look at items not so often carried
that can make a big difference if you get stuck out and which can help ensure
you don't do so in the first place.
GROUP SHELTERS/BIVI BAGS

A
standard plastic survival bag may get you through a summer's night in no more
than damp and chilly discomfort. On long, cold winter nights though
condensation will freeze inside, snow will blow in the opening and you won't
feel very warm. Far better is a waterproof/breathable bivi bag that can be
closed up to keep warmth in and snow out. A basic design is best, with a weight
in the 200-400 gram range. Insect netting, complicated openings and small hoops
all add unnecessary weight and bulk unless you intend to use the bivi bag for
nights out in summer. Bivi bags aren't just for overnights though. You can sit
in one at rest stops if it's very cold.
Much
better for this though is a group shelter or bothy bag, basically a large nylon
bag that will shelter from 2 to 10 people depending on the size. The warmth and
security provided by one of these in a blizzard is quite amazing. Inside you
can sit up, eat, drink, change clothes and talk to each other. If someone is
tired or hungry using a shelter can ensure that no one gets cold while they
rest and eat. In winter I wouldn't be without a shelter. I even carry a
2-person one on solo walks, using my rucksack or trekking poles to prop up the
end away from me.
SNOW SHOVELS
Good
though group shelters are when the snow is deep you can make a much quieter,
more comfortable and warmer shelter with a snow shovel. I am amazed that more
winter hillwalkers don't carry one. Being able to dig a snow hole has saved
lives. Apart from a snow hole a shovel can be used to build a snow wall or dig
out seats in a snow bank to protect you from the wind at rest stops. Also, if
an avalanche occurs a shovel is essential for digging for victims. I never go
out when there's much snow on the hills without a shovel.
HEADLAMPS, SITMATS &
CLOTHING
 |

A
shelter and a snow shovel are the two main items I think add greatly to safety
on the winter hills. There are other bits of gear that are essential though.
Firstly,
snow and frozen ground are cold to sit or lie on. A small closed cell foam mat
can make all the difference. Rather than the tiny sit mat I carry at other
times of the year I take one half the size of a full mat in winter. If your
rucksack has a padded back you can sit on that of course.
Most
walkers remember a torch or headlamp in winter. How many carry spare batteries though,
or a back-up lamp? Winter nights are long. If you have to walk far without
spares your light may fail, as I found out on a dark, wet night on Kinder Scout
many, many years ago. I've never forgotten spare batteries since. It's wise to
check your companions have them too though. I once had a difficult walk out
through a dense forest as the battery in my companion's headlamp had failed and
he had no spare (and mine was the wrong type for his headlamp of course). On
another occasion when my companion turned out not to have a torch at all we had
to spend an unintended night out in a bothy when it became too risky to
continue over icy terrain with just one light.

Carrying
a spare fleece or softshell top is normal in winter. This may be enough to keep
you warm during short stops but probably won't be if you're stuck for hours or
even all night. A down or synthetic filled garment can make all the difference
here and I always carry one in winter along with long johns and dry socks for
my legs and feet.
A
hat and mittens are essential in winter. But these items are easily whipped
away by the wind. I've seen it happen many times. The only time I've lost a hat
to the wind, many years ago on Helvellyn, my head and especially my ears
quickly felt so cold even with my jacket hood up that I had to go down. Since then
I've always carried a spare hat in winter. I learnt the same lesson for my
hands a few years later when a mitten, taken off so I could check the map,
slipped from under my arm and soared away into the sky. With no spares my hand
was soon very cold and again I had to descend. Now I carry spare mitts or
gloves and have loops attached to them so they can dangle from my wrists when
not being worn. If you don't have spares and you lose a mitt or your mitts
aren't warm enough spare socks can be worn on your hands. I've done this a
number of times and it's very effective.
SNOWSHOES/SKIS

| Snowshoes |
Finally,
a thought on how to travel over snow. It is now over three decades since I
first strapped on a pair of snowshoes and discovered how easy it is to walk on
snow rather than wade through it. Since then I've preferred Nordic skis to
snowshoes though recently I've been trying the latter again.
Plodding
through deep snow, postholing as it's called in North America, is slow and
exhausting. It can be dangerous too. People have died because the effort of
walking out through deep snow was too much for them. With snowshoes or skis you
can travel much faster with much less effort, floating on the snow rather than
sinking into it.
The
big advantage of snowshoes for walkers is that you
can
learn how to use them very quickly. Lessons aren't
needed.
They're also much less expensive than skis and
can
be used with ordinary walking boots. And they are much easier to carry on a
pack than skis. Also, in deep soft snow snowshoes are better than skis as they
don't sink in so far and are easier to manoeuvre.
With
snowshoes you can walk at normal speed rather than be slowed down by deep snow.
With skis though you can speed along, much faster than walking pace, in all but
the deepest, heaviest snow. In bad winter weather speed can be a safety factor
so both snowshoes and skis are preferable to being on foot.
I
find skis far more fun and efficient than snowshoes but you do need to spend
time learning how to use them, preferably on a course.
