Pulled aside the stone cairn. A probe and a dig pulled up a few more granite stones. No sign of bolt on rock but could easily be anywhere in adjacent gorse and heather.

On Tresco again, so I took the opportunity to see what my GPS gave as the coordinates of the cairn built on the assumed site of the trig point: SV 88769 15779, with an accuracy of 3m. If my GPS is right, the actual trig point should be somewhere to the SW of the cairn.

On Tresco again, I made another visit to Beacon Hill, in the hope that someone had cleared the gorse scrub from around the old lookout. They had cleared it to the south, but unfortunately, not to the north. I then spotted a new cairn to the north of the lookout, in the gorse. It was only when I read peregrinus's log that I realised its significance, and so returned to photograph it. [Additional note: 'Scilly's Archaeological Heritage', published by The Historic Environment Unit, Cornwall County Council in 1992, and revised in 2003, contains a record for Beacon Hill Lookout which says: 'South-east of the triangulation point is a rectangular platform on which stands the remains of a building, probably the ruined lookout recorded by Troutbeck (1796)'. This suggests to me the trig point was both extant and clearly visible in 1992; given nothing is now visible, it's quite possible it has been destroyed.]

revisited in passing to admire JonM's excavation. Prodded beneath then rebuilt cairn, prodded some more and added more rocks to cairn. No sign of block or solid outcrop. Tried metal detector app which suggested something present but position rather variable.

Came to view Jon Metcalf's hard work then disappeared to return on the 15:45 boat.

Had a good look around and dug out an old collapsed cairn with RHW but to no success.

Remains of old cairn at expected location: extensive digging failed to locate a bolt. Seems like the sort of place for a surface block but there could be an outcrop nearby under the heather /gorse

The summit of Beacon Hill (on Castle Down) is occupied by an old lookout. As jonglew notes, the trigpoint should be about 18m north of the lookout. Far from being the ‘Pleasant heathery top’ described by dal, this part of Castle Down is covered by impenetrable gorse and bracken, so I too failed to find the trigpoint. But the walk over Castle Down in the late afternoon sun was lovely.

OS records this as extant so it may well exist but unable to find it. GR seemed to indicate a point 18m N of Castle Down summit, deep in gorse and bramble etc. No rocks found in there. Nothing found on summit rocks either. ***Re-visited 7 Jul 2022. Had another token thrash through bracken and briar; poked around the cairn, but nothing found.

Pleasant heathery top - we could not find the Bolt - may well be hiding.
