Travelling around Australia the design of Trigonometric Stations or ‘Trig’ varies from state to state. Trigs are often in the form of a metal structure, wooden structure, concrete pillars, concrete pillars with vanes, bronze survey discs set in stone or a stone cairn. Stone cairns vary from a loose pile of rocks to substantial or complex structures 2 or 3 metres high. Trigs are well-known as collectables to geocache treasure hunters.

Hi Andrew. As a Land Surveyor I have to say that I am pleased to have found this page about Survey and Trigonometric marks along with the radio related things. I have seen a lot of them (and used) during the field work but I never took a photo…….shame. Best regards, Al, CX8AT
Nice collection of Trigs!
Thanks, it’s good to be outdoors searching for new trig types. I’m always surprised by the variety.
Andrew. Looks like my Little Joe cairn needs a littke help to catch up to the others!
If all VK3 activators would visit Little Joe in 2016, you may end up with a sizable cairn?!? Lets start a campaign for ‘Little Joe Cairn’. 🙂
