An employee and a second employee were cutting a log with a chain saw next to a storm water ditch. The employee walked to the downhill side of the log to position a 6-foot crowbar to assist with the log cutting. When he repositioned the crowbar, the log began to roll towards him and he fell into the ditch (approximately a 2-foot dry ditch). While he was in the ditch, another log rolled down. The second log crushed him and pinned him to the ground. He suffered a fractured pelvis and punctured bowel.
