Abstract: Employee #1 was hooking tree length logs on a line yarding operation. He was working approximately 500 feet down from the line shifter on a 55 to 60 degree slope. It appears that after he hooked up a turn of two logs, he gave the signal for them to be pulled to the log landing before he was fully in the clear. The tree logs had been lying at an approximately 90 degree angle to the skyline and as they were pulled up the hill they swung into line with the skyline. One of the tree logs apparently caught a stump or a standing tree, causing the top of the log either to swing more rapidly or to break off then flip and/or roll down the hill. Employee #1 was struck on his back and the back of his head. He died of massive head injuries.
