Logged with rogerw3 towards the beginning of our big trig hunting expedition in the area.

Wish all trigs were as easy to find as this one!

By comparison, the Pittwater Trig (hidden in thick bush but nearby) quite difficult.

Also found a NSW State Survey Permanent Marker across Mona Vale Road.

Anyhow, an unusual trig. The antenna on the top of this mast was designated an official trig and given its own 'TS Number' by the NSW Department of Lands.

Rated: for Overall Experience.
