Description
Seismic - Tarrawarra North PM 53
This Trig Point was discovered by me (Geodes) while searching for a spot to hide a cache. This particular point consists only of the marker (bronze disc) set into the ground and does not have the framework above it and is therefore a little more difficult to spot. As this point is right near the fence of the nearby Seismic Observatory, it's possible that the frame was removed to erect the fence, or maybe it simply never had one. Anyway, it's the 'Triangulation Station' marker that makes it a Trig Point, so I'm adding it to the database. To log the cache, you'll need to take a picture of your GPSr next to the marker.
Note too, that there's a GC cache (GC1QBQ7) less than 15m away and the cache page gives some tips on accessing this spot.
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.
Using the web-based "Survey Marks Enquiry Service (SMES)", the details for this survey maker have been acquired.
The name of this cache has changed from the former name "Blue Range Trig Marker" to the new name "Seismic- Tarrawarra North PM 53"

Logs
Since my eTrex10 has died I am currently caching with my phone. So a notepad will need to suffice for log proof here today.
Thanks for the Trig Point and the views.
One of the many trigs we have found in our travels.

The last few hundred metres to the fenceline might still have been a bit boggy for a 2WD at the moment anyway given the recent wet weather. Anyhoo, I finally made it to GZ at 14:45 to log its first find in 153 weeks! Unfortunately, there were only the barest glimpses of views between the trees but a great spot nevertheless.
Thanks Geocaching Australia.
I was in the kinglake area finding some Geocache.com caches when I noticed a few nearby trig points in my GPSr. This one was quite difficult to find and I actually walked over it once before I spotted it.
I chanced upon this marker while searching for a spot to place a cache. It's a neat location and I did place a cache nearby (see link in notes for this cache). The picture of my GPSr actually shows the distance and heading to the traditional cache, but it should be an easy find in any case. At the time, I took co-ords and some pics of the marker just for interest's sake - but when the GCA Trig Point caches were released, I remembered this one and have added it to the database. Personally, I don't count this cache type in my FTF count so, as I had an unfair advantage here, if anyone else does count them, feel free to claim the FTF here.
Bob.
