Description

A Trig Point is a virtual cache which requires a cacher to locate the Trigonometric Station at GZ and photograph it.

A trig point (also known as a Trigonometric Station) typically consists of a black disc on top of four metal legs or concrete pillar, resembling a navigation beacon. It is also accompanied by a metal disc, which is located directly below the center point of the tripod or on top of the pillar itself.

Trig points are generally located at the top of hills or points of prominence in the landscape. Many provide unique views and challenges, with some being difficult to get to.

These points were regarded as valuable to surveyors, providing reference points for measuring distance and direction, and assisting in the creation of maps.

To log a find on the Geocaching Australia website, you will need to include a picture of the trig point, along with your GPS receiver and (preferably) yourself. Long distance / telephoto type pictures are against the spirit of this cache. You are encouraged to leave a description of your journey in your log to help others in finding the trig point.

The original collection of trig points has been sourced from Geoscience Australia and may contain inaccuracies. This was 'sourced' rather off a 1st ed. 1:25,000 Knorrit Flat 9334-3N topo map. With an elevatioin of 334 m shown on the map

Please respect local laws and regulations when searching for trig points. If you believe that a trig point is located on inaccessible private property or in a dangerous location, you may archive the cache, by clicking on Log this Cache and place an "Archived" log on the Geocaching Australia website.

1545 While I have had the maps showing that there is a few Trigs out this way unpublished It took having this one published to give the impetus to get out and find it. Being quite a sunny afternoon I actually parked on the opposite side of the road in the shade. Then walked an access track to a closed gate - easily around that, then just had to find a way up from the road. Once up to the fence line the way was a bit clearer from the multitude of cycads growing up the hillside. Couldn't see the trig until almost 20 m from it. The base is in good condition, but there must have been a bushfire a few years ago that melted the white plastic pipe, so the black vanes are lying on the ground beside it. There is also a cairn of rocks very close by, but I couldn't see any survey marker around on rocks (like at Pinanpinga). Lots of birds and a couple of wallabies, but no reptiles.

Tiri trig is shown on the Knorrit Flat map, but it would be hard to see it from most places, except for Dingo Peak and maybe Pinanpinga. There is quite an extensive stand of cycads on this mountain, even tho it appears to have had a fire up it in the last year.
The white painted concrete pedestal is intact, but the cannot be said for the plastic pole, which has been melted, leaving the black vanes on the ground beside it. There is also a partly dismantle rock cairn beside it, but no sign of the post or vanes from the original one. Couldn't see a State Survey Marker on any of the rocks at the top.
There is some nice views to the North and West.
