Stated that EE was cutting down a tree while doing clear cutting work. At the time EE did not notice that a grapevine attached to the tree was underneath the leaves & was under EE's left foot. When the tree fell, the grapevine went with it, tangling EE's foot in it & drug EE down the hill 10'-15'. It chipped EE's left ankle. 2 Screws and a plate were put in EE's foot, & 6 staples.
