The Meltdown on The Quarryman wall in north Wales' Dinorwig Slate Quarry was equipped by Johnny Dawes—who appears in this short film. But turning his attention away from the line in 1990, it became known as 'Johnny's great unfinished project'. It remained like that until James McHaffie's first ascent in 2012 to give the UK its 'technically hardest slab climb at 8c+/9a'. Six years later (May 2018), the visiting Spanish climber, Ignacio Mulero, repeated the route on his second trip to try it. In this film, his friend Talo Martin documented that visit and the successful outcome.
