2torial #0472:
Learn2 Improvise
a Compass (Day and Night)
"North? That's UP, right?"
Whether climbing at Annapurna Sanctuary or
wandering in the local park, it's a good idea to
know your direction. Knowing that the sun sets in
the west doesn't do the trick. But even if
celestial navigation is more reliable, how does it
help on a day hike?
This 2torial will cover three different methods,
two by day and one by night: Use your Watch, Use a
Stick, and By the Stars. Each of these methods will
enable you to better understand your locale--there
is actually a basis for navigation, you know.
If you have become lost, don't panic. Relax, sit
down, and come up with a solution to the problem,
or at least a plan. If it is Daylight Savings Time,
turn your watch back an hour before you calculate
your direction.
Method 1: Use Your Watch
(Daytime)
Prepare your watch
Hold your watch flat, with
the face towards the sky.
Position the stick
Place the stick upright (towards the sky) at the
tip of the hour hand (the little hand).
Adjust your watch
Turn the watch until the hour hand points to the
sun. The shadow of the stick should fall exactly
over the hour hand.
Method 2: Use a Stick
(Daytime)
Position your stick
Find your stick, then find a sunny patch of
level ground.
Position your stick
Poke your stick into the ground, tilted so it
points into the sun (and casts no shadow).
Be
patient
Wait at least 15 minutes until the stick casts a
shadow around 6 inches long
Add
the finishing touch
Draw a line straight across (perpendicular to)
the shadow line.
Read the results
Voila! You've got your compass. The stick is
your west point and the end of the shadow is the
east. The cross-line goes from north (on the right)
to south (on the left).
Method 3: By the
Stars (Night - Northern Hemisphere
Only)
Find your sticks.
Find the North Star
The North Star can be found by following up the
outside edge of the bail ("scoop") of the Big
Dipper. Follow the line through the sky. The
biggest shiniest star in that direction is the
North Star. (The North Star is the first star in
the handle of the Little Dipper.)
Plot the placement of the
sticks
Draw an imaginary line from the North Star to
the ground. Stand facing the "point" where the line
touches the ground. Poke holes into the ground for
the sticks, a couple of feet apart, along the line
between you and the "point.
Order the
sticks
Place the sticks in the ground so you see the
tip of the shorter one first, then the tip of the
longer one, then the North Star.
Finish it
off
Draw a line in the dirt between the two sticks.
The stick closest to you is South, the one farthest
is North.
