Wales could have a new ‘super mountain’ after a group of amateur hill sleuths turned their attention to a Snowdonia peak.

Glyder Fawr, overlooking the Pass of Llanberis and the Ogwen Valley, is listed by Ordnance Survey on its maps with a height of 999m (3,278ft) – just one metre short of the magic 1,000m mark that would elevate the mountain to a super league with only four members south of the Scottish border.

But the trio of amateur surveyors who recently pronounced its neighbour Tryfan as a munro-equivalent 3,000-footer has been out with high-tech GPS gear again to settle the argument about Glyder Fawr’s height.

At present, Snowdon stands proud at 1,085m, with its outlier Crib y Ddysgl on Garnedd Ugain just 20m lower. Carnedd Llewelyn at 1,064m and its near neighbour, the 1,044m Carnedd Dafydd complete the metric giants in Wales. But the survey by Graham Jackson, John Barnard and Myrddyn Phillips could add a fifth member to the exclusive club and possibly add an extra peak to the Welsh 1,000m race.

The three men have carried out their measurements in collaboration with Ordnance Survey, the Snowdonia National Park Authority and the National Trust.

Their results will be revealed later this month at a gathering in Maentwrog in the Vale of Ffestiniog.

There are 133 mountains in Scotland over the height of 1,000m, and three in the Republic of Ireland. England has none, its highest peak, Scafell Pike, falling short by 22m.
