In reply to DH3631:
> Culter Fell and Hart Fell, both in the borders, come to mind, and most probably there are others around there. However, as mentioned above, there are numerous 'vals' on various islands, although off the top of my head I can't think of any on the mainland west coast, apart from Conival.
Conival is more likely (but not certainly) Cona' Mheall; like the Cona Mheall down the road by Inverlael.
Another doubling-up Western Isles quirk would be Loch Langabhat.
