Finding Your Direction When
Lost
The Shadow Tip
Find a straight stick about a meter long and locate a level spot with no
brush in which a shadow will be cast. Place the stick in the ground and
mark the shadow's tip. Wait 10-15 minutes until the shadow tip moves a
few centimeters and mark the shadow tip's new position. Then draw a line
through the two marks to obtain an approximate east-west line. The first
mark will always be west. Stand with the first mark (west) to your left and
the second mark to your right. You are now facing north.
Using a Watch
If you have a watch with hands, it can help you
find your way. The direction will be accurate if
you are using a true local time with no changes
for daylight savings time. Also, the further you are
from the equator, the more accurate this method
will be. If you have a digital watch, all is not lost.
Just draw a circle on a piece of paper with the
correct time shown. Assuming you are in the
northern hemisphere, hold the watch horizontal
and point the hour hand at the sun. Bisect the
angle between the hour hand and the 12:00 mark
to get a north - south line. If you have trouble
deciding which end of the line is north, remember

that the sun rises in the east and sets in the west.
It is due south at noon, east before noon, and west after noon. Note: If
your watch is set on daylight savings time, use the midway point between
the hour hand and the 1:00 mark to determine the north - south line.
The Night Sky
To locate the North Star, the Big Dipper (Ursa Major) and Cassiopeia are
helpful, because neither of these constellations ever sets and thus are
always visible on a clear night. After finding the North Star, imagine a line
drawn from the North Star perpendicular to the earth. The point at which
the line reaches the horizon is north.
There isn't a star bright enough to be easily recognized near the south
celestial pole, so you can use instead a constellation known as the
Southern Cross. It has five stars, of which the brightest four form a cross
that tilts to one side. The pointer stars are the ones that form the long axis
of the cross. Determine south by imagining a distance five times that of
the two pointer stars. The end of the imagined line is in the general
direction of south. Look to the horizon for a landmark to steer by.
Moon
-You can use the moon to determine a rough east - west direction.
If the moon rises before the sun sets, the illuminated side will be west. If
the moon rises after midnight, the illuminated side will be east.
Moss-
The old saying that moss grows on the north side of a tree is only
partially accurate. Moss does grow on the north side of a tree; however, it
also grows on the south and all the way around. In reality, moss growth is
more vigorous and lush on the side of the tree facing the equator.
Vegetation and Moisture-
North-facing slopes receive less sun than

south-facing slopes and are therefore cooler and damper. In the summer,
north-facing slopes retain patches of snow. In the winter, trees on south-
facing slopes are the first to lose snow and the ground snowpack is more
shallow.
Making a Compass-
Use a piece of ferrous metal that can be shaped into
a needle or use a double-edged razor. You will also need a piece of non-
metallic string from which to suspend the metal. Polarize the needle by
slowly stroking it in one direction through your hair, using deliberate
strokes. You can also polarize the needle by stroking it repeatedly at one
end with a magnet, rubbing in one direction only. If you have a 2 volt or
higher battery and some wire, you can polarize the needle electrically. If
the wire isn't insulated, wrap it in paper to prevent contact. Coil the wire
and place the ends on the battery's terminals. Repeatedly insert one end
of the metal object in and out of the coil. The needle will become an
electromagnet. When suspended from a non-metallic string or floated on
a small piece of wood in water, the needle will align itself with a north -
south line.
