N-S by the Equal Shadow Method
-Place a stick vertically in flat sandy ground. This
stick should be placed before noon and should cast a
shadow at least a foot long.
-Place a stone or peg at the shadow tip.
-Draw an arc the radius of the shadow with the stick
as the center.
-The sun's shadow becomes shorter at noon and then
starts to get longer and it will cross the drawn arc.
-Mark the spot where the shadow crosses the are.
-Draw a line straight line though the marks and this
is the East
-West line.-Draw a line perpendicular to the line and
it will indicate North-South.
