A Portland teenager has died after a big tumble down Rocky Butte. Austin Fisher, 16, died at Legacy Emanuel Hospital where they were trying to treat his critical injuries sustained in the fall, officials said. The boy fell an estimated 80 feet off a cliff on the east side of the butte. “Another by passer found the young gentlemen who was around 16 years old, unconscious and then called 911. When fire crews transported him out as fast as they could. Paul Corah with Portland Fire said the boy was goofing around with his buddies when he fell. This appears to be an accident he says.  Corah adds this was the third fall this year from Rocky Butte. Last June, a 19-year-old woman was rescued after she fell while hiking. And back in May, a climber from Austria fell about 50 feet and died.
