Pillars on islands

[Moacky]

Having visited two of what I call 'single pillar islands' this year - Ailsa Craig and Hirta (St.Kilda) I was wondering if there is a complete list of these islands, and a list of other islands with the number of pillars on them? I had a look at Harold Street but to my inexperienced eye I can't make a search work for this combination. Cheers, Peter.

Alex Cameron is your man for island pillars - the Halseys list can be found here: http://www.haroldstreet.org.uk/trigpoin ... st=halseys

Excellent stuff, I knew there'd be a list somewhere, cheers, Peter.
