Remembering
the classic Rule of Three, brings us to our final topic in our Spring Survival
Series. It is said that a human can
survive three weeks without food, three days without water, three hours without
shelter and three minutes without oxygen.
Many find it hard to believe the ‘three hours without shelter’, perhaps
because they have never been wet, standing in gale force winds, in freezing
temperatures.
Maintaining
a functional body temperature is critical for human survival. While we have developed phenomenal clothing
to help protect us from the elements, high energy and easily portable food to
sustain our energy requirements, and effective water purifying and/or carrying
strategies, we still may need to seek shelter from environmental elements such
as wind, sun or precipitation.
The
wind is highly effective at robbing heat.
The wind chill factor is evidence of the role wind plays in how humans
perceive temperature in the presence of wind.
Adding the factor of wetness, either from sweat or an unexpected dip in
the lake, and you may quickly find yourself cold on a warm day. Shelter from the wind in a form of a wind
block may look like another human, a rock formation, or dense brush.
Most
of us have experienced the saving grace of shelter on a hot summer day when we
go stand in the shade and immediately feel the relief from the sun’s
radiation. Thankfully in Northeastern
Nevada where the relative humidity is low, the temperature between a sunny spot
and a shady spot can vary greatly!
Finding shade not only lowers the ambient (surrounding air) temperature,
it minimizes the physical effects of direct exposure to the sun, sunburn.
While
the shady side of your car or trailer is an obvious shelter, the landscape of
Nevada may prove difficult for finding it elsewhere. In some areas, the lack of vegetation taller
than a foot is a real issue. Carrying a
small tarp and parachute cord in your backpack may help alleviate this. Often we think shelters need to be tall but
remember you can also lay under a shelter.
Depending on how long you need utilize your shelter, you may need to
have an adaptable shelter. Be sure to
not use all your resources on one iteration as the shelter may need to be
relocated or shifted to accommodate the location change of the sun or the
direction of the wind.
It
is also important to remember that a shelter does not necessarily need to be a
structure. For example, wrapping
yourself in your sleeping bag is a form of a shelter. Being aware of how much warmth the ground
draws from our bodies is also important.
The process of buffering your body from the ground by sitting on your
backpack when resting on a cold day, is another form of seeking shelter. Likewise, if conditions become desperate
enough, your backpack may also be utilized as material from which to fashion a
structure. Being creative in the use of
available materials is encouraged when shelter is required for survival.
Get
outside and explore nature! Enjoy the
dynamic conditions of spring in the mountains and on your local streets. It is wise to think about shelter
alternatives and be prepared to create a shelter so you are not caught
unprepared, your life may depend on it.
