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.

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.

The Big Western Australia trip in 2018. Day 2. Today took me me back on the main roads from Albert, Nyngen and Bourke to a favorite bush camp on the Mitchell Highway. See GA10096. This was a short walk into the station to get to the trig. It was all there, just lying down.

Thanks

It has taken us some time to work through all the photos we took whilst on our major excursion to get to Brisbane (for a family wedding) via Griffith, Cobar, Bourke and Stanthorpe. It was a great trip, one which we will remember for a long time because of the very different landscape types that we went through, the unique characters of each of the towns visited, the wildlife (we hadn't seen very large flocks of emu roaming before)and the different community activities and tourist features.

As we travelled from Nyngan to Bourke, we came across a few trig points along the way. As the Byrock Station Homestead Area trig had not been found for such a long time, we stopped for a while and headed off through the scrub. After about ten minutes we came across the remains of a beacon vane and a steel pin in the ground at the location defined by the coordinates. This trig point has obviously seen better days but we were still pleased to find it. Two photos have been added to the Gallery: Mrs y'stassie standing next to the yellow vanes on the ground; and the steel survey marker peg in the ground. Thanks Geocaching Australia for the cache.

PS: The original log for this cache is not the Byrock Station Homestead Area trig but TP2642 Trafalgar Homestead Area Trigpoint which is further towards Bourke and right on the edge of the road. Comparison of photos in the Gallery for this cache and that from Trafalgar supports this assertion.

ack son of hack

well just going thru some old pickies and found thin one. I remembered I took this for a Trig cache. not only that but it was an historic one as it was on the Bourke Base Line. The NSW govt decided to improve the geographical survey for better land development as farming was getting more involved and important. Therefore from 1890 to 1916 the trigonometrical survey was extended. their was two base lines one around Lake George near Canberra. A baseline needs aprox 20 miles along a flat straight surface and all sorts of triggy measurments can be worked out by the boffins. The Bourke Base line was started in 1911 and by 1916 the Lake George triangulation had reached the Bourke Base line.At this time it was partially suspended due to the war.
Work was continued in 1927. on March 26th 1931 the final details were forwarded to the Surveyor General.
Thanks Acko
