Steps taken to boost appeal of unique rock formation
MACLEAN's iconic rock formation The Pinnacles has received a much-needed upgrade, with a new viewing platform and staircase.
Clarence Valley Council natural resource management coordinator Rodney Wright said the upgrade will make the site more welcoming for tourists.
"A lot of people originally would have briefly paused and then kept going, so the work will definitely encourage more people stopping and having a look," he said.
"It's a very unique geological formation, there's probably no other like it in the country because of the way it was formed, so that's why the work has been undertaken because of its potential to be a significant tourist attraction."
Mr Wright said geological reports indicate the Pinnacle Rocks and the nearby cliff are composed of Cretaceous-Jurassic Kangaroo Creek sandstone on top of Jurassic siltstones of the Walloon coal measures. During intense rainfall or a minor earthquake, the weaker siltstones can give way underneath the heavy sandstone.
The Pinnacles were formed when a large bowl-shaped landslip caused part of the cliff line to break away, and slide downhill for about 30 metres. During the landslip, some of the cliff line collapsed into a pile of large boulders that were strewn down the hill for hundreds of metres, but part of the cliff slid in one piece without collapsing, which created The Pinnacles.
Mr Wright said the sight was significant for the Yaegl People, with council working closely with Yaegl Local Aboriginal Land Council during the redevelopment.
"There will be interpretive signs that highlights the importance of the site to its traditional owners," he said.
"Maclean Landcare were also active around the lookout area and provided significant input into the work at The Pinnacles."
