1. Hold the stick at its base vertically,
making certain that the length of the stick above your hand
equals the distance from your hand to your eye.
2. Staying on the same contour as the base of the
tree (in other words, don't go up or down hill) move away
from the tree while sighting the trunk base above your hand.
3. Stop when the top of the stick is level with the top of
the tree. You should be looking over your hand at the base of the
tree and, moving only your eyes, looking over the top of your stick
at the top of your tree. You are standing at the point where, if the
tree were cut, the top of the tree would land.
Measure how far you are from the tree and that measurement -
in feet - is the tree's height.
