You could join the happy band of Triggers. The Munro pillars are some of the easier ones to find as there is a well trodden path to each, and plenty of route descriptions etc. Others (not conviniently situated at the top of a mountain) are overcome by gorse or in the depths of sitka plantations. and you need protective gear to get out alive.Some, like the one at NH557477 on the Beauly Firth, a mere 2 m above sea level, have been buried by the landowner to discourage visitors.
These are just the pillars, there are also the fundamental benchmarks, (approx 200), lower order benchmarks (250,000) and tidal gauges ( to measure mean sea level). The Munro pillars barely scratch the surface of the whole triangulation story which has now moved on to use approx 1000 passive stations and GPS technology. Bet you wish you'd never asked!
