Outdoor Navigation Tips
Hiking, and in particular hiking in remote areas, is a great
experience if approached with due regard for fitness, safety and
skill. One of the major skill categories, is the ability to
navigate with or without compass and map. Ideally, no one should
head off the beaten track without map or compass, but what if
you find yourself in that situation, or you lose or damage your
compass? Here are a few basic 'skills' that could one day be of
use.
FINDING DIRECTION BY USING YOUR WATCH... If you have a watch
that is working correctly, you can always quickly determine the
points of the compass as long as the position of the sun is
visible. The method used varies depending upon which hemisphere
(northern or southern) that you happen to be living in.
The following methods are described using an analog watch,
(that's a watch with an hour and a minute hand) but they can be
applied just as well if you own a digital watch - just use your
imagination to superimpose the 12 hourly numerals and the
relevant position of the 'hour hand' on the face of your digital
watch.
NORTHERN HEMISPHERE Holding your watch horizontally, point the
'hour hand' of your watch at the sun. Note the direction that
lies exactly midway between the 'hour hand' and the numeral
twelve on your watch. This will be South. Once you have
established this, it will be easy to determine the other points
of the compass.
SOUTHERN HEMISPHERE Holding your watch horizontally, point the
numeral twelve on your watch at the sun. Note the direction that
lies exactly midway between the twelve and the 'hour hand'. This
will be North. These methods will give you a good approximation
of compass direction. If your watch happens to be adjusted for
daylight saving at the time, then 'remove' the daylight saving
for greater accuracy.
Another method of determining compass points can be used if you
do not have a watch. This method takes longer and also requires
enough sunlight to cast a shadow...
TO FIND NORTH WITHOUT A WATCH Before noon, on level terrain,
position a stick of about 3ft upright into the ground. Mark the
tip of its shadow with a peg or stone. Using the tip of the
shadow as a radius, draw an arc around the stick. The shadow
will shorten as it approaches noon, pulling back from the arc.
It will then lengthen again - where the afternoon shadow once
again touches the arc, place another peg or stone. Now draw a
straight line between the two pegs/stones - this will be an
East/West line, with the first peg being in the westerly
direction. You can now draw a North/South line at right angles
to the East/West line.
The following (less accurate) method can also be used at any
time of the day without drawing an arc... Peg the tip of the
first shadow, then about 20min later peg the tip of the moved
shadow. Draw a straight line between the two pegs, and this will
be an approximately East/West line, with the first peg again
being the westerly one.
A typical error when lost, is a tendency to wander off what you
may think is a straight line bearing, sometimes even slowly
circling back on yourself. To prevent this, note an object
(tree, rock, terrain feature) that lies directly ahead of you in
the direction you wish to travel, then aim for it. When you
reach it, take another bearing on the direction you wish to
head, sight another object directly ahead of you and repeat the
process.
In areas of restricted distance visibility, you may have to
repeat this quite often over short 'legs' to ensure that you are
remaining on course.
KEEPING A COURSE BY THE CLOUDS... What if it's a cloudy day with
no sun visible to get a bearing on, or the bush canopy prevents
you getting a clear "shot" at the sun? Well, if you're lucky, it
may be windy with the clouds moving in a constant direction -
note the directional flow of the clouds, and adjust your course
relevant to their direction. e.g., If the clouds are moving from
your front from right to left over your shoulders, keep them
there, at the same time, sight an object straight ahead of you
and head for it.
To retrace your steps in the same general direction, just do an
about turn, then keep the clouds moving from behind and now left
to right over your shoulders, and repeat the process.
As an example of 'cloud navigation', once, when moving inland
through dense bush away from a coastal beach, I eventually
decided to retrace my steps to where I'd left my kayak.
Surrounded by dense undergrowth and trees, I realized that I
didn't have any idea in which direction the coast lay. Before
entering the treeline, I'd noted that the clouds were moving in
a direct line from the trees to the coastline - it was just a
simple matter then of looking up and following the direction of
the clouds to enable myself to head in the correct direction and
once again access the beach.
Being aware of your surroundings will often pay off, so try to
cultivate that habit.
