If you're wondering what I'm on about, I didn't know what they were either.

They are, it seems, the – usually – concrete pillars built by Ordnance Survey in 1936 to safely house their theodolites which are used for measuring the lie of the land.

If all that sounds a bit boring just look at some of the amazing photos of them bearing in mind most are situated very high up indeed.

I do rather like the Minion but my favourite is the one at Ben Ledi, Perthshire, with its stream of rime ice. Breathtakingly beautiful. But brrrr!

    We have some photos of these - taken by hubby over the years on his many hill walks. There are nearly always fantastic views if the weather is favourable.

    Re the one on Ben Ledi - many years ago we took our boys to Callander for a week`s holiday. Ben Ledi being its `local` mountain, you could get Ben Ledi anythings in all the tourist shops. Simon, puzzled by the popularity of Ben Ledi, said, " Who was he anyway, and what did he do ?"

    I think on a good day, the one on top of the Bealach nam Ba, the pass from Kishorn to Aplecross has to be a favourite of mine.

    When I first crashed out with RA and was in bed for some time I read a book called "Map of a Nation" by Rachel Hewitt, a biography of the Ordnance Survey. The book was very well reviewed and I found it a fascinating read and it is all about the setting up of the trig points.
    I have kept my copy and still occasionally dive into it. The sad thing is that gps mapping is superceeding the old method and trig points are seen as superfluous which I think is a crying shame as they were remarkably accurate and should be treasured.

    I guess it's just fascinating in so many ways - history, geography and photography.
