Trig Pillars & Theodolites…

Steve Ellis News

Summers evening on Sugar Loaf…

If like me you have stood atop a UK summit and wondered “what is this white (sometimes grey, red, cream…) concrete block, with a three-pronged brass threaded insert set into the top for?”…well read on dear friends and your questions will be answered!

How many trig pillars have you visited this year?

Which one do you remember most and why?

For me, its Sugar Loaf, it was one of our daughters first self-supported summits, aged 7½! Although I did carry hot chocolate and a hearty picnic…c’mon, it was January!
