why this is called Invergroin when it's on the top of Beinn Bhreac is all rather strange, again the centre is missing

Nice summit, grass and rock, simple steep ascent from S. vgc, no cap or plug. Crisp winters day, climbed out of the cloud into sunshine.

Despite rain the view down Loch Lomond was still pretty good. I didn't hang about long though.

HISTORY: Pillar completed 21st August 1956 costing 99.0s.4d, and levelled for height to Class 2 precision also in 1956. During 1957 this marker was computed as tertiary triangulation station NS29/T58 within the Greenock secondary block. Last routine maintenance by the OS was undertaken in July 1982. SITE VISIT: Overall approach from SSE. Parking at NS329979, followed forest track through first wooded area, then NE parallel with streams, upwards towards left of rocky outcrops onto summit plateau. Pillar stands on rocky summit of Beinn Bhreac. Column in good condition. Spider centre open. Flush bracket faces SW, compass measurement 249. Back sighting hole open, others plugged. Full 360 panorama includes Doune Hill, Ben Donich, The Brack, Beinn Ime, Beinn Narnain, and Ben Lomond.

Very fine viewpoint for Loch Lomond. On a remnant knoll after landslip activity. Plug gone, there is a chunk of quartz protecting the hole. OS have the pillar marked in the wrong place on their yellow covered 1:25000 map, the current edition is correct.

tannoy announcement "fire awareness training has been cancelled" scared me a little as I was coming off the summit and I hadn't planned on going to any seminars that day!
