An employee was cutting a large tree (135') in order to provide an anchor point for the yarder. When the tree came down, it landed on several root wads that were on the ground from a previous felling operation for road clearing the year before. The rood wads moved another tree (50') that was covered with brush. The arms of the tree that was on the ground came up and struck the employee in the face. The employee sustained a concussion, a broken and lacerated nose, severe bruising and a fractured eye socket, and a punctured lung.
