Size matters for hill reclassified as 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).

Using "state-of-the art" equipment supplied by Swiss firm Leica Geosystems, the trio used satellite positioning to gauge the height in Snowdonia.
