Description

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

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.

Along the Eyre Highway they typically consists of a black rectangular cross on top of a two piece metal pipe which sits in a slightly larger pipe base set in concrete which usually has an alpha/number code set into the concrete. There should also be a "Warning - Standard Survey Mark" placard on a metal post near the base. Originally the top would have been guyed by three twisted wires running to three star pickets. Alternatively there may be a "Warning - Standard Survey Mark" placard on a metal post and a bronze plaque set in concrete usually within 1.5 metres of the placard.
 

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.

Please respect local laws and regulations when searching for trig points. If you believe that a trig point is located on 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.

If you feel that you can add to the description of this trig point or adjust the difficulty / terrain ratings, please feel free to edit this cache and amend the information suitably. Vandalism of the cache description or other information will result in your account being terminated.

After spending a few days in Gawler it was time for to drive my mums (well my car now) from Gawler back to Perth. This was day three travelling from Border Village to Norseman on a 5 day 3,100km adventure. It was bleak and cold morning and stayed overcast much of the day. Not as many sights today as there was on day 2.
And there are hundreds of signs saying do not drive tired so geocaching helped with that.
The day turned eventful after gashing my leg at a cache, putting a tiny hole in my font tyre returning from Madura Cave then at Norseman the motel i had booked with did not have me on their list, so managed to get a room at the pub. They do say they come in threes.....
I parked up on the side of the road for the start of many trig points.
I cleaned quite a few so any writing could be seen rather than just a mound of dirt with a pole.
This Trig was a very quick find.
Thanks for the trig cache Geocaching Australia ClappingClan Minotaur

Could have driven right to this one but walked anyway. There was only a pipe at GZ and absolutely no other sign of a trig.
Took the photo of this one with the GPS sitting on the top of the pipe. Thanks.

There are many of these trig along this stretch of the HWY traveling west. All very close to the road so it makes it a quickish stop and find and take the shots. These trigs you need to go to ground zero as they are either a steel short post or a peg in the ground. You may be lucky to find the remands of the steel fin trig around the area. One or three of them will still have the fins in action. It looks like these trigs haven’t been used in many of a year. I gather as there isn’t any development around the greater area there isn’t any need to use them. At some trigs, you will find little rubbish or a lot of rubbish. It’s been an eye opener at what items I have seen today – 1 place there was a smashed fish tank & others truck tyres – A big thanks for the series along this stretch of the road. Clan Griffin

Day two of my 90 Mile Straight Trig Point Odyssey Very Happy
Stop two of day two of my 90 Mile Straight Trig Point Odyssey Very Happy
Will I ever find a trig point intact around here so I can get an idea of what they originally looked like ?? Shocked

Not here Sad
Another lonely looking bit of pipe sticking out of the ground with only a few scraps of wire and half a star picket nearby to show this was once a proud Trig Point !! Smile

Another quick one while travelling West to East.

A nice quick find while travelling the Nullarbor.

Easy access and a great reason to stop and stretch the legs.

When we arrived at GZ all we found was a vertical short length of water pipe. We dug away the sand that had built up around the pipe and discovered the concrete base with letters/numbers scratched into the concrete when it was wet.

WanderingAus wandered by on day 113 of a "climatic refugee" trip, heading home far too early imho, but The WanderingMrs (aka SWMBO) has a function she MUST attend next Saturday. Two days of storms, heavy rain, and very strong head winds has had us using far too much fuel, so it was nice to have some sunshine and only moderate headwinds for a change.

I hadn't made a real find since Ceduna, but I'd been looking at all these benchmarks in NT, SA and WA. The WanderingMrs had set a distance limit of 300 metres if I wanted to hunt down more than one, and until we went down the Eucla Pass they were all further away or on top of ridge lines, not particularly accessible.

Once we hit the "Ninety Mile Straight" they became very accessible. I parked on the edge of the road again on a good wide verge, and the Explorist said "49 metres to next". An easy walk through light woodland, and I spotted a pipe sticking out of a windrow left by a grader. It appears as if the grader driver spotted the pipe and swerved just a smidgin to miss it, but almost covered it with the spoil. The number for this one is a mystery, as it is between NMF123 and NMF124.

I rate this a Difficulty 1 Terrain 1 cache, and if there was a GAFF rating of 0 this would deserve it. I did a "GoTo" on the Magellan Explorist but left it set at 2.5 Km scale. I didn't do a "Navigate To" on the TomTom, but when the icon appeared on screen about 900 metres out I used it to determine where to stop and where to find the Trig Point.

*Recommended* *Overall Experience: 2* *FTF*
