Claim: The highest point of the Glyderau mountain range is Glyder Fawr with an elevation of 1000.8m or 3283 ft.
Evidence: Glyder Fawr is a mountain in Snowdonia, Wales, the highest peak in the Glyderau range at just over 1,000 metres, having had its height recalculated in 2010 using GPS. Until late 2010, most maps showed the height of Glyder Fawr to be 999 metres (3,278 ft); however, the mountain was resurveyed with accurate GPS equipment and its height was found to be 1,000.8 m (3,283.5 ft).
