Those who like to get out their climbing gear
and take on the challenges of Tryfan may be delighted to hear that the height of the Welsh mountain has been confirmed at over 3,000 ft.
Marked on Ordnance Survey maps
as 915 m - or 3,002 ft - it had been suggested that the peak could be lower because of the margin of error in aerial surveys and a trio of amateur boffins have been re-surveying it using the latest technology.
Using GPS measuring equipment John Barnard, Graham Jackson and Myrddyn Phillips have been measuring the height of Tryfan this week amid fears it could be struck off the list of Welsh 3,000-footers after their studies did the same to Munro Sgurr nan Ceannaichean last year.
But the new measurements put the height at 917.5 m - or 3,010 ft, meaning the mountain is higher than previously believed.
As a narrow ridge in the Ogwen Valley, Tryfan offers a wide variety of climbs and scrambles, such as its famous north ridge.
Other features include the two summit stones known as Adam and Eve, with the 'freedom of the mountain' being gained by jumping from one to the other.
