The man had taken a significant fall into a river gully and sustained serious injuries. In an operation involving the Air Ambulance, Welsh Ambulance Service paramedics and the Coastguard helicopter R187, the man was stabilised, then winched from a very difficult position for onward transport to a critical care facility.
Aberdyfi volunteers helped set up a rope system to provide a safe exit for around 10 medical responders at the casualty site in the bottom of a gorge.
Everyone was back at vehicles by 7:45 p.m.
