after finding Trig - Euro Ku-Ring-Gai Chase, New South Wales, Australia By Geocaching Australia on 28-Apr-11. Waypoint TP5750 I started looking for this 1 & was found pretty well, this area has much history to be found of rock art & latter. Around GZ area there are other drilled holes but this 1 is in the details of survey reports. This dates back to 1974 timeline – maybe earlier.

Rated: for Overall Experience.
