Trigonometric Stations and Survey Plates

Traveling 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.

    • 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’. 🙂
