Description
A Trig Point is a virtual cache which requires a cacher to locate the Trigonometric Station and photograph the GZ.
Official Code: PM90207
Official Name: Kingscliff Baseline PM90207
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.
Trig points were regarded as valuable to surveyors, providing reference points for measuring distance, elevation, and direction, and assisting in the creation of maps. The series of "Kingscliff Baseline PM" 'trigs' is for the training of surveyors, and calibration (if need be) of their 'equipments'. This series seems unique, in that the trig pillars are not a regular distance apart, with some hundreds of metres apart, with another very close. These work in the exactly the same manner as any other NSW concrete trig pillar (where the measurement device is mounted with the three screws, on top of the pillar).
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.
Please respect local laws and regulations when searching for trig points. If you believe that a trig point is located on private property, and permission to photograph it is not forthcoming, 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.
Access: Just a nice beach-side walk is required to find the SEVEN (x 7) similar trigs - NO VEHICLES allowed beside the trigs

Thanks for the cache.
Left the car and went for a quick wander up and down the line, collecting photos as we went.
The seven Baseline Trigs all look the same. TP7253 Kingscliff Baseline PM90201 shows I’m at this location. I’ve added the remaining six Trig images in a collage with the log for TP7254 Kingscliff Baseline PM90202. This is my seventh Baseline Trig find of the day out of seven. They are all close together. No interesting story with these finds so here’s some random information about 7, shamelessly copy/pasted from my log at TP13399 CHANNEL 7..
Blanche’s Dissection refers to the simplest dissection of a square into rectangles that all have the same area but are of different sizes. There are 7 rectangles in Blanche’s Dissection - the square is 210 units in each side - so its area is 210 x 210 = 44100 square units. This means that each rectangle has an area of 44100 / 7 = 6300 square units.
Interest history about why they are here. Thanks for the TrigPoint cache.
This is probably the easiest baseline trig series that we have ever done. Did one on the way up north and it involved bush bashing and up and down steep hills and across a busy road.
Compared to that this one was a walk in the park!!!!
Did have to remember to do something slightly different with each photo so I could tell them apart later.
Quite often they have graffiti which helps you distinguish them but not this lot!!!
Thanks.
Note: Photo didn't load with log through app. Photo lost.
Caching in the area with whitewebbs and snapped this trig.

Out and about caching in the area with Tassie Trekkers and we stopped to take a photo of the trig. TFTT
In effect the last PM90207 was our first, found while one half of the team was 'using' the nearby facilities.
Thanks for the trig.
*FTF* @ 1005, and a Merry Christmas (I had just returned from 3 weeks in Thailand)
