Managed to get the car off the road at nearest point to the trig. Short walk over rough ground. 1" domed bolt on bare rock. Approx 0.5m E of cairn.

Bolt in rock easy to find, within 0.5m of NE base of cairn. Nice spot, lovely views. Soay More Block which we found yesterday is only 3 km to the W: strange there are so many assorted trigs hereabouts. Found this as it was already on the POI file - nice work sheepsocks :-)

View W to Soay More + Beg Taransay to R; Bolt is L of cairn from this direction
View N from trig Oreval L, Sron Scourst R; Bolt is R of cairn from this direction

This is a bolt which is marked on the OS map with a triangulation pillar sign. There are others in the Outer Hebrides previously logged by Peregrinus. The coordinates entered are not GPS accurate, they are map and ruler accurate. Gets a 9 as its my first user added and it has stunning views over the Loch a Siar and north eastwards towards the Gleann Langadail...NOTE TO ADMIN..correct grid reference is NB 09708 04840 (OS database calls it Tolmachain T1NB0904)
