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.

I’d give the terrain on this once a little more. But that’s just my aging body. Great work out and a great view.

Spotted this a few days ago

I was in the area collecting some GC caches and spied this trig very close to one of them! So took a snap and found it listed here as I assumed!
Thanks Smile another trig

I didn't think to check if there was a Trig here. Fortunately I spied it!

Went straight up the side! Benchmark YA90, 813m

I took a walk up the hill here to find two GA caches and this trig. The sky was showing signs of the wet weather to come.

a magical misty morning walk along issacs ridge. beautiful views from the trig point - above the clouds!
 
04-Apr-16
This was a good destination for a walk from Long Gully Road today.

Great views for my first visit. Thanks

It's all about the Trig (and Paris Bear).
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

F(H)ound it! 9:30am

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.

Ribbit See what a beautiful day it was? Clear blue skies and great visibility. Beautiful views over towards Mugga Mugga. TFTT Ribbit

Another trig to add to the collection. The crows seemed to be enjoying the trig frame today.
 
15-Jan-15
Took a slight detour on my way home just to get it. Steep walk up but nice views and breeze at the to. Took an hour to get here but work looked close.nearly walked a 10km circle I guess.
 
01-Sep-14
Beautiful view - breathless. See pic. Thanks.
 
17-May-14
Out exploring with Boot65 stopped to take in the views.

I climbed Isaacs Ridge with the Canberra Bushwalk Club this afternoon. A beautiful afternoon to take in these views. We could see where they were burning off on Black Mt too.
 
19-May-13
Passed by the Trig while walking 2 sections of the Canberra Centenary Trail with Tealby. This was a great day to be on the ridge with clear blue skies giving great views. TFTC

Nice trig, with great views of the mugga mugga pit.
 
28-Aug-12
Great views up here!
 
19-Aug-12
Last week I tackled Isaacs Ridge from the southern end. Today, I started at the northern end tp try and gets the ones I ran out of time to get last week. After a tiring climb (I dont remember the Ridge being that steep), I got to the top and took a few moments to enjoy the great views from here.

Thanks for the trig.
 
08-Mar-12
It looked like it might poor any moment but the sun was still out coming trough in places. A spectacular evening walk with awesome views to be had -- see picture.
 
Been here before chasing a GC cache but no photo. So returned today. Came up the shortest way through the pines, got a bit steep in places...Anyway a pleasant breeze kept the temperature comfy for walking. Nice views from here.
 
22-Dec-11
5th and final today on a huge walk up and down Isaacs Ridge. After a long walk, we finally got here! Already got the nearby cache before GCA, so had to come again! Nice views. Saw some Yellow Tailed Black Cockatoos on the way home too as a bonus. TFTC Geocaching Australia! Very Happy
 
24-Oct-11
Thought i'd grab this one, whilst grabbing the GC cache nearby..
 
16-Sep-11
Easy to find, highest point in the facility. Cool

Looked all around the trig station - no luck
 
10-Jul-11
Found this one today on my stroll up here with BatGirland Co and mr_roo. Another of the 'one day' hills now conquered.
 
03-Jul-11
Another one where I know I was here before but I cannot think when. Needed to be up here again anyway so why not?
 
13-Jun-11
The walk up here was lovely at this time of year, glad we didn't try in summer though as the exposed fire trail would have been hard going. Great views but didn't want to hop the fence so took pic of trig from fenceline. TFTT Smile
 
19-Feb-11
Came up here for the traditional caches and to grab the trig at the same time. Wet old day to be here, but the views of a wet Canberra were pretty good.
 
05-Feb-11
GCA 54 - 3504 - Catching up on logging some GCA Trig 'finds'...

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 !!
 
27-Nov-10
After completing a nearby cache Albida decided to go back to the car I headed up this way tho to get this cache and a few more. Always great to get another trig
 
13-Nov-10
164. Just having done the TE II2 cache it wasn't a big ask to do this trig Razz . Photo taken and back down we go.

TFTC and the toss.
 
02-Nov-10
Found while tracking down a couple of TankEngine caches in the area. Wasn't even aware of this trig being here so it was a nice surprise/addition to my caching activities. Photo to be uploaded soon.
 
31-Oct-10
Just popped by whilst doing the Issaacs Incline II. Wind was blowing, Patterson's curse out in full, rye grass getting up my nose!
 
29-Sep-10
I own a Magellan Triton and its batteries died with no spares on hand - everything going against me! This unfortunately meant no Isaacs Inclines and Rattus, but a little persistence allowed me to bag my first trig with the sun disappearing behind the mountains.
 
03-Sep-10
I had claim this while I was in the area at a nearby GC.com cache, but have made a few notes for future trig point claims!! Great views from up here, as one expects from all trigs!

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.

Grabbed a photo of this nearby trig when doing Tankengine's newish cache - it's been on my "to do" list for quite some time.
 
17-May-10
Nice walk to the trig and I happily picked up the nearby GC.
 
01-May-10
Some great views of the Canberra suburbs
 
30-Apr-10
Found this while doing the nearby Isaacs Incline ver II cache, I didn't have a camera handy so left my mark on each of the legs, A 'two for', two for the price of one at least. Outstanding view as always with any of Canberra's hills.
 
12-Apr-10
Found while racing up the side of the hill in the faint hope of an FTF on Tankengine's new Isaacs Incline. Made it. Smile

Unfortunately, my phone doesn't take great pictures of Trigs in the dark.
 
11-Apr-10
Wow - was it ever eindy up here today! Nice views. Top spot.
 
26-Dec-09
Being almost locals we know these tracks, and made a nice afternoon walk of this trig, dragging Jasper along (or did he drag us along!) After about two inches of rain, we weren't troubled at all when more fell along the wall - getting pretty steamy inside the raincoats as we climbed the hills though! We made this into a big loop from Farrer to the trig and home by the towers south of the trig.

I have never been up to this spot before and I really enjoyed the awesome views from a different perspective.

In the spirit of previously visited spots I was here on 29/6/07. Albida
 
26-Sep-09
A 5ºC day, drizzle, gales up the top of many trig hills, horizontal rain up there too – or was it horizontal snow? In other words, an extreme caching day collecting 10 Trig caches, and one determined to be no go.
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.

Since I seem to have a big mouth about getting trig names right I should put my hand up and say I made the mistake of calling this one Sheaffe on the waymarking web site. I wrote

"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."

Found on a Sunday morning caching trip.
