Lists
Thirteen lists people bag. Here’s how much Ordnance Survey actually marked.
Each takes its membership from its own authority — Munro’s Tables, Alfred Wainwright’s guides, the Ordnance Survey itself. None of them print how many of their summits also carry a trig pillar: the one fact that says where Ordnance Survey chose to build, not just how high the ground is.

Trig Pillars
