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).

After Ben Starav which is a hard walk.Dropped down to Bealach at Allt Mheuran source.Choices are. Drop down the ridge Southwards to Beinn nan Aighhenan and slog up the ridge for 1500ft or from the Bealach, head East and up 350ft to Glas Beinn Mhor.My hopefull judgment was to head to Beinn nan Aighhenan knowing that the 1850ft had to be regained to take in Glas Beinn Mhor.This was not as bad as it first looked at least on the ascent of Beinn nan Aighhenan.Reality kicks in when you drop back down and see Glas Beinn Mhor towering above you only 1850 ft to reach its summit.The best way back to Glen Etive is to take the summit path of Glas Beinn Mhor over to Alt Mheuran.I would not fancy the very steep descent on its NW slopes.A truly huge walk and one that took over 10 hours
