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).

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

Pen Llithrig y Wrach (2500ft+) , in the Snowdonia National Park (Wales), is a relatively low and rounded hill overshadowed by its neighbours the Carneddau, hence it is less frequently visited.

Pen Llithrig y Wrach forms a single long and broad structure running NE to SW along the W side of Llyn Cowlyd Reservoir, above which its SE slopes rise steeply to culminate in crags with the summit close to their edge. Its lower NW slopes overlooking Cwm Eigiau are also craggy. From the summit a short broad ridge descends gently NW then turns W and down to Bwlch y Tri Marchog (c.615m), the col with Pen yr Helgi Du (833m) leading to Carnedd Llewelyn (3000ft+) .

Pen Llithrig y Wrach can be approached from Llyn Eigiau Reservoir to the N; or its southern end can be approached by a boggy track from Tal-y-waun farm in the Llugwy valley.

Hazards you may encounter on Pen Llithrig y Wrach include

General Considerations
