Gallery of log for Gungahlin Trig
The two trigs you found, Mt Reedy (TP5698) and Sparrow Trig (TP5439) BOTH have a "Trig" PLATE identifying the place as a TRIG.
This location does not, by your own rules - the one you found Mt Neighbour (TP5699) HAS A BOLT (an old relic part of the old trig that was there.). A threaded bolt. So, I took a picture of just sucha "trig" here. LOL. And, the yellow "trig" indicator is also visible, LOL.
History - The yellow SURVEY POSTS replaced many old survey locations (some trigs included)circa 1960's. They DO NOT automatically represent trigs, as trigs did not exist at all yellow post SURVEY MARKS.
As for the relics of the trig - LOL - I went there AND FOUND THE THREE THREADED BOLTS THAT FORMED THE OLD TRIG, see my pics.
