Cold
weather camping as defined by BSA is “camping in weather where the average
daily temperature is below 50 degrees Fahrenheit and conditions are cold , wet, or windy.”
The most dangerous. Wide
temperature variations from melting during the day to freezing at night makes
proper dressing difficult, and important. Damp conditions from melting snow or rain makes keeping dry difficult.
Ground is frozen and snow is dry and crystallized. Strong winds cause the most concern with keeping warm. Extra clothing layers and wind-proof outer garments should be added.
Requires insulation and wind-proofing. Many materials change physical properties, becoming brittle. Only for the most experienced campers.
The
most important thing to remember about cold weather camping is to KEEP DRY. Moisture will reduce the insulating
properties of almost anything. To keep
yourself warm, remember the
C-O-L-D.
C keep yourself and
your clothes Clean
O avoid Overheating
L wear clothes loose and in Layers
D keep Dry
Before You Go:
·
Introduce yourself to winter travel and camping through short overnight
trips.
·
Plan an itinerary that offers “escape routes.”
·
Test all your gear at home; -30 degrees is no time to realize your
stove doesn’t work.
·
Check the local weather
forecast.
·
Know yourself and your group’s limitations. You are a team and your team is only as
strong as its least able member.
·
Know your skills, have confidence, but don’t be over confident.
·
Know your equipment, how to use it, and how to repair it.
·
Be aware of the surrounding
terrain, avoid thin ice and stay off of ice covered streams and creeks.
·
Know your route, getting lost in cold weather can be deadly.
·
Maintain a good sense of
time. Try to set up camp before dark.
·
Have a good first aid kit.
·
PLAN, PLAN, PLAN
The C-O-L-D key to keeping warm applies to
the clothing that you wear. Here are some
ways you can use it:
C Keep clothing CLEAN. Dirt
and grease clog air spaces in the clothing and reduce its insulation
value. When cleaning, make sure all the
soap is rinsed out, because soap residue can reduce insulation qualities.
O Avoid OVERHEATING. Select the clothes that you need to stay comfortable and even slightly
cool. It is better to be cool than run
the risk of perspiring and reducing the insulation value of your clothing. If you are too warm, loosen closures a few at
a time; if you are still too warm, remove a layer.
L Wear LAYERS. Layers of clothing should be long and loose
fitting. Not only does this allow more
freedom of movement, but it lets your blood circulate freely, preventing
frostbite. Select clothing that is the
correct size and care for it so it retains that size.
D Stay DRY. It is important to keep clothing dry outside
as well as inside. Do not get so warm
that you start to perspire. Do not let
snow collect on the outside of your clothing. The heat from your body melts it and some will penetrate even water
repellant fabric, reducing the insulating properties of the fabric.
Layering For Winter
How to dress
smart and stay warm when Old Man Winter blows in.
Winter clothing keeps you warm
primarily by trapping warm air next to your body (insulation). But when being
active in winter and spending multiple days in the same clothes, insulation
alone is not enough. It has to stay dry, not just from the outside in, but from
the inside out. This is where specialized outdoor clothing is literally a
lifesaver. Wearing cotton or other moisture-retaining fabrics puts you at risk
for serious heat loss.
Any moisture that remains in your
clothing quickly conducts body heat straight to the atmosphere. This means your
active clothing (as opposed to the super-warm down jacket that you only wear in
camp) must not retain perspiration; instead it must quickly transfer body
moisture to your outermost layer, where it can evaporate. The key is to wear
layers made of synthetic, quick-drying material that helps evaporate your
sweat. That way, your clothes aren't wet enough to transfer a significant
amount of heat away from your body.
The advantage to layering, of
course, is that when working hard and starting to overheat, you can simply take
off an insulating layer (usually a fleece jacket or vest), replace your
windproof shell, and you're on your way. When inactive and cooling down, you
can replace the insulating layer.
From bottom to top, here are the
layers you should include in any cold-weather travel:
Underlayer:
·
One
or two pairs liner socks (thin, quick-drying)
·
liner
gloves
·
Synthetic
underpants
·
Synthetic
long underwear tops and bottoms
Insulating layer 1:
·
Thick
insulating socks (one pair per day)
·
Synthetic
pants
· Synthetic shirt
Insulating layer 2:
Outer layer:
·
Down
jacket, preferably with waterproof/breathable outer material
·
Shell
pants, waterproof/breathable
·
Shell
jacket with hood, waterproof/breathable
·
neck
gaiter or scarf
·
shell
mittens of waterproof/breathable material
·
hat
(fleece or wool)
·
brimmed
cap for warm, sunny days
·
boots,
waterproof and roomy enough for thick socks and toe-wiggling to prevent
frostbite
·
gaiters
·
goggles
(for wind and snow)
·
sunglasses,
sunscreen and lip balm with sunblock
Fleece offers more warmth for the
weight than wool, but some still prefer good old wool. Goose-down is the
warmest for the weight, and should be included for rest stops and while hanging
around camp, so that you can maintain a constant body temperature between
exercising and resting. It also compresses easily for stuffing into a pack. But
don't break a sweat while wearing it; it dries poorly and won't keep you warm
when it's wet the way fleece or other synthetics do.
With today's synthetic clothing,
socks are the only thing you need to change in the backcountry (dry feet are
absolutely essential to preventing frostbite). Bring a pair of insulating socks
for each day, ideally with a plastic bag for storing each separately.
Cold Weather
Sleeping Systems:
Sleeping condition is one of three factors that can make or break a cold weather camping experience, along with keeping warm and having the proper amounts of food and water.
You may encounter controversy about which kind of
bedding is best for cold weather camping, but your choice will depend on the
type of cold in which you camp. Many
factors contribute to the selection of bedding, but the following points apply
to all cold weather camping situations:
·
The body cools down during
sleep. The blood (heat) is drawn from
the extremities (feet and hands) and brought to the center, or core, of the
body.
·
In all cold weather camping
situations, the ground is colder than the body. Proper insulation must be provided to prevent heat loss by conduction.
·
C-O-L-D, the key to staying warm,
is as important as it is with clothing.
C Your bedding should have a
washable liner so that it stays CLEAN.
O To keep from OVERHEATING, Your bedding must be ventilated. Overheating in a sleeping bag produces
perspiration just as when you wear the wrong clothing.
In Bed Tips:
·
Your sleeping bag will
absorb several hundred calories worth of body heat during the first few hours
of the night to bring it up to sleeping temperature. So, do jumping jacks or take a hike before
you go to bed – anything to raise your core body temperature to start the night
warm. Be careful not to over do it and
begin to perspire.
·
Use two sleeping pads under
your sleeping bag. A self-inflating foam
mattress together with a closed-cell foam pad makes a warm comfortable
combination.
·
Sleep on top of your coat
and insulated pants. Put your gloves,
socks, boot liners, and tomorrows clothes inside the
sleeping bag.
·
Wear warm, loose-fitting
layers to bed. Always wear a hat. Booties worn with clean, dry socks help keep
feet cozy.
·
Vent your tent. Leave one door partially open at the bottom a
second door or window open at the top to allow cross ventilation and to prevent
frost buildup.
·
Slip a hot water bottle
inside your bag, but make sure the lid is tight. This gives you handy water to drink in the
night and unfrozen water available to cook with in the morning.
·
Flare open you boots as wide
as possible so you can slip them on more easily in the morning when they’re
frozen.
·
When nature calls, don’t
hold it. Keeping fluid at body
temperature uses up energy better spent warming your body. A pee bottle can save you a nippy trip
outside of the tent. Make sure the
bottle doesn’t leak and the cap is on tight. Also label the bottle, so you don’t drink from the wrong one.
·
Keep some
high-energy food handy for
·
Be careful not to breathe
inside your bag. Humid breath can lead
to frost buildup.
·
No open flames (candles,
matches, etc.) inside the tents
Shelters:
Finding shelter
from the elements in winter is an important consideration for overnight camping
or in emergency situations. There are
several options available, using items you have brought with you, or natural
shelter sites. It is recommended that
you always carry a small waterproof tarp or reflective emergency blanket. It provides an excellent lightweight
emergency shelter as well as a ground cloth for your tent. Tents are most popular because of their
portability and convenience. Tents for
winter camping should be able to withstand heavy snow loads and strong
winds. Natural features such as low
hanging evergreen branches or large rocks can often provide shelter from the
elements. Avoid areas that that could
drift overnight in high winds. Another
option that provides excellent shelter and insulating qualities is to construct
a snow cave. Be cautioned that a certain
amount of experience is needed to build one correctly. Never construct a snow cave alone it could
collapse while being built. Also constructing a natural lean-to shelter from deadfall ahead of
time works great. (Like Troop 325
did.)
