Glyder Fawr

English/Welsh
Quick Facts
This is the height of the mountain above sea level. However, on the climb, it is the ascent that matters, i.e. the sum of all the uphill parts of the route.
Altitude
999 m (3277 ft)

This is the standard notation used on Ordnance Survey Landranger maps.

Each reference consists of two letters identifying a 100,000 metre square block then three digits defining the Easting and finally the three digits defining the Northing with reference to the South West corner of the block.

NN166712 is the grid reference for the summit of Ben Nevis. Where you are given the map number ( For Ben Nevis = 41) it is acceptable to omit the two initial letters e.g. 166712. (Instructions on how to read the references are given on the OS maps).

The UK is covered by 204 Ordnance Survey Landranger 1:50,000 scale maps. Maps numbered 1 to 86 cover Scotland but for the highest mountains (Munros) only 23 maps are required. The name given roughly describes the area covered by the map.

A description of the characteristics of the mountain including any hazards of which you should be aware.

  Description
Glyder Fawr (3000ft+) is the highest top of the mountain group lying S of the A5 Llyn Ogwen/Nant Ffrancon road and N of the A4086 Capel Curig to Llanberis road in the Snowdonia National Park (Wales). Its northern flanks are craggy with several cwms (corries) two of which have llyns (lakes).

The summit of Glyder Fawr is a broad stony dome, from which an undulating ridge runs E over Bwlch y Ddwy Glyder (919m) to Glyder Fach (994m), a substantial subsidiary top characterised by curious formations of slabs of rock lying on edge with a few erratic blocks resting loosely on top. The ridge then continues E to Y Foel Goch (805m) and Gallt yr Ogof (763m) before descending to the Afon Llugwy near Capel Curig, a total distance of 8km.

Approaches from Llyn Ogwen show the topography to best advantage, and enable the traverse to be combined with Tryfan (qv), Y Garn (qv) or both of these.

Hazards you may encounter on Glyder Fawr include
 Steep slopes on or near ascent routes.
 Stony/rocky Slopes on or near ascent routes.
 Crags near summit.
 Scrambling (minor), easy hand and footholds.
 
General Considerations
 Temperature decreases by 1degree C for every 100m of ascent.
 Wind usually increases with altitude.
 Visibility can change markedly with cloud level.
 River/Stream levels can increase markedly in one day.
