This trip report -
Cave / tunnel beneath Invincible Trig
This report is only on the cave / tunnel
just beneath Invincible Trig
in Ben Bullen State Forest.
It is a cave with 2 openings ... like a tunnel.
The cave can't be seen from the trig area,
because it is over the cliff edge.
It is not documented anywhere on the web ...
Except here 😊
And not mentioned by Yuri Bolotin
in Walks 5.18 in the book
"Gardens of Stone National Park and Beyond"
Book 5
(by Michael Keats & Brian Fox)
Just curious 😊 ...
- Has anyone been to this cave / tunnel ?
- Were we the first group here ?
