Description
This is a Trig cache. It is a virtual cache. There are no physical geocache containers with logbooks or swap items here.
So what exactly is a Trig?
"Trig" is the abreviation of Trigonometric Station/Point. They are, or in most cases were, used by surveyors to create accurate maps of the area. Trigonometric Stations are named as such because trigonometry calculations are used to map out the location.
Over time there have been various mapping methods some of which were a little innacurate. Over the last 100 or so years Trigs have proved to be a fairly accurate tool when surveying. More recently though, technology has proved much more reliable. However, if technology suddenly failed forever and all maps went up in flames with it, we would have a great network of Trigs to start over with as seen in THIS MAP.
The locations, aka points or stations, where the surveyors made these calculations from were saved for future surveying using markers. These markers were meant to be permanent, however people have changed the landsape through things like farming and town growth and development meaning some of these markers have been removed. Luckily with the use of satelites and other amazing technology the older markers are pretty much unnecessary for surveying now. But they are great historical markers and fun to find, especially if left long forgotten in the middle of the bush like buried treasure. The long list of trigs on Geocachign Australia will help you find these Trigs.
Across Australia and New Zealand you can find a number of different styles of Trigs. Commonly they consist of a copper pin hammered into the ground or embedded in a concrete pillar with a stand and vane of some shape above it making it easier to find from long distances like other nearby Trigs. A few examples are in the images below:

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. Accessing these Trigs is at your own risk. Please respect local laws and regulations when searching for trig points. If on private property, always seek permission to visit the Trig beforehand. If you think this trig listing should be archived because it is inaccessible, no longer exists, or is in a dangerous location, please log a 'Needs Archiving' log with explaination.
To log this trig as found, take a photo of the Trig with yourself or your GPS or something that represents yourself and proves you were there. Upload the photo with your found log. Other photos of the trig or area are always welcome.
If you can add information to this trig listing, such as access instructions or interesting facts, please add it at the botom of this description. All GCA members can use 'Edit this Cache' to add these details.

This Trig is a survey marker on ground level in the carpark at a lookout. Originally (prior to 1971) it was a sandstone block depicting the point as a Trigonometric Station. As read in the details of it's Survey Mark Sketch, the original sandstone block is still in place... kind of. It is now lower in altitude than it originally was because surveyors (or thier minions) dug a hole and buried it beneath the now visible concrete blob with metal plate survey mark on top. If no one is paked on top of it, you don't even need to leave your car to find this one if you really wanted. Just park in the right place, hold that camera up and take a happy snap of yourself with the concrete blob in the background. But why not get out, stretch the legs and enjoy the view or even a sunset whilst here. And if someone is parked on top of it (like I actually did trying ot drive as close as possible to GZ whilst reading my GPS), you'll just have to wait for them to move or come back another time.
Logs
No one else around when I visited. I could hear the singing of the kids from the nearby Christian school though. Nice to have another trig marked off the list. Cant help but think a NSW style concrete pillar with mast and vanes would look good here though. Shame they decided to bury the sandstone marker.

I’d forgotten about that and how much I liked it
A newly published Trigpoint Cache close to work.. and on a street called ‘Beacon’ Road haha. Such a shame the original sandstone block is no longer visible. This Trig extends my week long adventuring of hiking, camping, and geocaching an extra day. I’m on my way to work now so I’m sure this cache will be my highlight for this fine Monday which I’m okay with Memories flooding in about my week while I write this log include my 4 day solo hike, keeping dry and warm while raining in a dry cave drinking a hot coffee, a splendid sunset on night 2, solitude for my soul, nature, 4WD tracks, Earthcaches, the echidna I saw near the Mount Mia Trig point, the discovery of coordinates of a 6m high Trig built in the 1940s not yet published in GCA, the interesting adventurers I met, especially Corals (with an s) and sooo much more. One of the best weeks I’ve had in many years.
Some nice information in the cache description and some great Trig images. Thanks for sharing and thanks for the cache.
Cheers
3.5 years ago I determined that a trip to Tambourine Mountain was to be done. I figured that I might as well get it done at last to pass time in my second week off. And why not explore that area on Queensland Globe while I plan for it. I was going to stay overnight, but forgot it was school holidays for pretty much all of Australia, so the cheapest available accommodation was more expensive than driving up there and back from Lismore 2 days in a row in an old gas guzzler 4WD with petrol at $2.20 a litre. I didn't end up getting to return the next day because a slippery path in the Botanic Garden did some damage to my knees. The fall even stopped me from visiting the Skywalk which was the one main thing I was going up there for. I really enjoyed the area and will definitely return again soon. [No Tomorrow adds Tambourine Mountain on the list of possible places to retire if she won the lotto]
I had planned to head up Monday... and then Tuesday, but the rain would really dampen the visit. Waking early Wednesday I consulted the trusty satview.bom.gov.au and deduced that the rain should have stopped by the time I got there. So off I went. It was raining the whole way till I was at the bottom of the mountain. The skies were clearing and the sun was shining. Yes!!! As I climbed higher and higher I discovered that this mountain was a bit of a cloud catcher. I was trapped in a thick fog all day. No rain though. The cloud was only just blown away right before sunset which was when I arrived at GZ.
I slowly pulled in to the carpark here and watched my GPS to see where GZ was. As I drew to a stop I realised that survey marker I just parked on top of might be it. I moved forward a bit and sure enough, that was it. Just an inornate blob of concrete with a survey mark on top. But I knew what lay below. I knew the significance of the mark. I considered if it was worth $200 to dig it up. hahaha. Not really. Okay, I did think about it, but only because the threat was written on the marker.
There were a heap of school kids here from the camp next door when I arrived. Thankfully it was too cold for most of them to stick around. Their teachers stuck around though. I got the impression most of them were sticking around to give one with a fancy camera the impression they were interested. They were mostly kicking around in the dirt instead of looking out at the horizon but could go at any time they liked. As soon as the camera guy who carried himself like he was in charge said he was done, they all agreed with him that they were ready to go too, even though the best colours of the sunset were still to come. Must be city folk not used to sunsets.
The sun had set behind a cloud, not the horizon yet, and everyone left, leaving me on my own to enjoy the colour changes of the sky. As it darkened around me, I realised I would normally fall asleep shortly, but had a long drive home ahead. Bugger. I flicked through my Audible app - nope, they'd all put me to sleep. I flicked through my subscribed podcasts on Spotify - nope, they'd all put me to sleep. I flicked through my Spotify playlists - not that one, or that one, they'll put me to sleep. I finally found a playlist I could sing along with that would keep me awake. I also found some chocolate and Krispy Kreme donuts at a petrol station on the way home.The quick and easy way home. Geeeez the road between Lismore and Murwillumbah via Nimbin is shit atm!
So there you go. A whole heap of shit no one will bother reading, or if they did they will question why the funk they did. You're welcome. It's really all just here as a kind of Dear Diary for myself.
