An experienced climber plunged 82ft to his death after storms turned the cliff he was navigating into a crumbling death-trap.
Craig Harwood, 53, was killed instantly when he landed head first on rocks after falling from the treacherous cliff face.
The fell runner and marathon mountaineer, from Macclesfield, was unaware that part of the cliff had collapsed in the earlier extreme weather.
The conditions made his established route, which he identified in a climbing guide, a deadly one.
The tragic adventurer was on a climbing holiday with fellow mountaineer Paul Headland, around the established routes at Compass Point, near Bude, Cornwall, on September, 4 last year.
His inquest in Truro heard that due to poor rock quality, his ropes and safety harness had been rendered useless.
When he fell he ripped out five steel pegs from the crumbling cliff face.
Following the tragedy, guidebooks are now being re-written to take into account the changing cliff
