A 68-year-old man has died after he collapsed while walking in Penyghent on Saturday morning.
The Cave Rescue Organisation has said that the man had already felt unwell on his ascent of the Yorkshire Dales peak, but still continued to the top.
After beginning the descent, he collapsed and lost consciousness.
The next people to come along were all medical professionals, so when it was necessary they attempted CPR and kept it up, until relieved.
A road ambulance, an air ambulance and CRO were all dispatched.
Arriving on scene first, the air ambulance paramedics continued CPR and the helicopter flew down the hill to pick up CRO members and road-ambulance paramedics.
CPR was halted more than an hour from the collapse with the man confirmed dead at the scene.
A CRO spokesman said: "The air ambulance flew the deceased down to Horton in Ribblesdale, for hand-over to the road ambulance and police, while CRO members checked on the other members of the party and withdrew from the hill."
