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.

Thanks another trig
Lovely Sunday morning doing the Isaacs Ridge walk, accompanied by a little black terrier, who appeared from nowhere, walked with us for 2 hrs, before trotting off home. A different walk starting off in a pine plantation, before heading up onto an exposed ridge, with good views.
Thanx GA for including Trigs as loggable caches, as Trig walks are what got me into Geocaching in the first place
The RP and I spent the morning grabbing a few caches around Isaacs and found this Trig on the way.
When I was a teenager I used to mind a pony that was kept in the nearby paddocks so I have been up this hill countless times before.
Was a trip down memory lane (or up) for me.
Thanks for the trig.
Found this one on 7 July 2010 when finding the nearby GC cache Isaac Incline II. Great views from up here on this ridge !
TFTC !!
TFTC and the toss.
Note to self: don't rely on blackberry or smartphone for trig point photos - they don't have a timer.
Note to self: don't take photos of self from arms length away.

Unfortunately, my phone doesn't take great pictures of Trigs in the dark.
I have never been up to this spot before and I really enjoyed the awesome views from a different perspective.
Pics taken at all of them, some easy jaunts in suburbs, some a stiff climb in the rain/snow/gales, some with great views of a rain covered Canberra or suburbs. It was spectacular views from some of them seeing a rain soaked Canberra or nearby mountain ranges. All in all, a great day with three FTF’s too.
"I got the trig name wrong. It should be called YA90.
Sheaffe is a survey point (three yellow concrete guide
posts) located north along the ridge at S35º 21.570
E149º 07.137. It is still worth the walk. Sheaffe is a
more interesting name and relevant as a surveyor of
the ACT. YA90 is named after a droid from Starwars
who's scenes were all cut in the final editing."
