The splitting of the butt of the log during the latter part of the fall. The tree
often remains attached to the stump, thus creating a danger zone and ruining much of the
Caused by a Dutchman notch.
Lodged Tree (also called A Hung Tree)
Limbs or other material thrown back toward the logger when the falling tree contacts
standing trees or fallen trees.
Caused by not felling the tree in a clear path or onto a clear landing.
(also called A Hung Tree)
A cut tree that has not fallen completely to the ground, but is lodged or leaning
against another tree. This is extremely dangerous. Do NOT work in the
presence of hung trees. Have these death-traps pushed or pulled down by a machine.
Caused by poor judgment of felling path or inaccurate cutting.
The seat that interferes with the smooth closing of the notch.
Caused when one of the notch cuts is made too deep and extends beyond the endpoint of
the other notch cut, known as "Bypass".
When a falling tree hits the ground or other object it can bounce back causing the log
to move back over the stump with great force. This is the main reason you should
never stand or retreat directly behind the tree.
Increased chance of kickback by not making the back cut above the notch on a
conventional or Humbolt notch.
A tree that has just begun to fall but is stopped by its
own stump. This is almost as dangerous as a lodged tree and
requires a machine to push it over.
