Geograph - photograph every grid square

The Ordnance Survey trigonometrical column on the summit of Snowdon was demolished and replaced by a topograph; some Ordnance Survey hardware from the trigonometrical column and a meteorological station being incorporated into this. When in situ in the original Ordnance Survey column the flush bracket, benchmark number 10684, marked a height of 1086.002m above sea level (Ordnance Datum Newlyn), last levelled in 1961 (photograph SH6054 : Flush Bracket Benchmark, Snowdon Summit).
On a misty day, the three men standing idly chatting on the summit regrettably did not think that people waiting to take photographs was a good enough reason for them to consider moving politely to one side.
