From the BBC: Survey turns hill into a mountain.
A Welsh hill has been upgraded to a mountain after three walkers found its official measurement was just too low.
Mynydd Graig Goch in Snowdonia was originally put at 1,998ft (609m), just short of the magic 2,000ft (609.6m) that qualifies as a mountain.
But the walkers found its true height is six inches over 2,000ft (609.75m).
Their efforts have echoes of the 1995 film set in Wales which starred Hugh Grant as The Englishman Who Went Up a Hill But Came Down a Mountain. [continue]
