Large bolt, ~2.5" dia, found in a grassy depression ~3m S of the summit rock. Dug out by Chris and I. Unsure if it's installed in concrete or rock as insufficient turf surrounding it was cut away. 3 witness rivets located on nearby outcrops.

It is possible to land on St Helenís, though it would probably mean hiring a boat. Bennett Boatyard is based at Green Bay on Bryher, but has hire points on St Martinís and can deliver to Tresco by arrangement (see http://www.bennettboatyard.com/boat-hire-scilly.html). Perhaps next time I visit Scilly Iíll hire a boat and visit this trig point. Until then, St Helenís is easily seen from both Tresco and St Matinís.
