I have decided to disable this cache, as recently muggled, as well as availability of nearby Earthcache. Apologies to anyone who had plans to find this original cache at this site. Thanks to those who have previously made the effort to locate this one! Good Geocaching to everyone from the CoomaClan.
A short stroll from the starting point to the rock wall. The cache is located a short scramble up from the features briefly described here.
Cooma’s Lambie Gorge is a site of cultural significance to the Ngarigo Aboriginal community. The local Reconciliation Group received an Environmental Trust grant in 2004 to develop a walking trail in the Gorge so its significance could be shared with the wider community.
The Gorge is also of historical and technological significance in the European settlement of Cooma and in the development of the Snowy Mountains Scheme. It was where Snowy engineers conducted experiments to develop rock-bolting technology from an empirical and temporary technique to a permanent one, founded in structural design and rock mechanics. This enabled the conversion of freshly exposed unstable rock faces of caverns and tunnels, into a structural mass that required no external support.
In addition to laboratory testing, early field tests and in situ experimental work was done in Lambie Gorge adjacent to the Authority’s Scientific Services testing laboratories in Cooma up until June 1962. The site is still accessible and shows the remnants of a succession of experiments, with a variety of bolt types.
At the test site there are 50 or so holes drilled into rock faces,
where rock bolt pull-out tests were conducted. Some of the holes still contain rock bolts, some bolts are cut off and some are partly separated from the vertical rock face. There was a succession of vertical faces into which holes were drilled for the insertion of the bolts to be tested. When the surface of each face had been fully used the cliff was blasted back to expose a fresh face for another set of tests.
This can be seen, and explains the broken rock in front of the test site, with some of the rocks showing drill holes.

If you want to head further along the track to the Lambie Gorge lookout take care as it is recommended for able bodied walkers (even though it is a short trip to the viewing platform)
