The
top cut is the first of two cuts that result in a Humbolt notch. The notch is made
on the side of the tree that faces the direction you want it to fall.
1. Starting Point
Important -- begin at any height as long as you
allow enough room for the undercut.

 |
 |
2. Angle of Attack
Important -- cut flat and horizontally.
|
3. Ending Point
Stop when the cut reaches 1/4 to 1/3 of the trunk's
diameter or when the cut reaches 80% of the tree's diameter at
breast height. |
