Members of the Calder Valley Moorland Rescue Association were called out this afternoon to help save a teenage cyclist who had fallen 100 feet down a ravine off Pennine Close, at Shibden Head, Queensbury.
The 18-year-old had been mountain biking with friends when he hit a rock and was catapulted down the incline.
Ambulance and fire crews from Illingworth, Halifax, also attended but it took over two hours to safely haul the patient back up to the ambulance.
He was taken to Huddersfield Royal Infirmary where he was being treated for serious leg injuries.
The teenager is believed to come from the Queensbury area.
