Newcastle's picturesque coastline may not be readily associated with volcanoes and ancient forests, but scratch beneath the surface and you will quickly gain an insight into a landscape that is more than 250 million years old.

Science enthusiasts and nature lovers are invited to experience the amazing geology of the coastline through a virtual fieldtrip as part of National Science Week.
A public webinar hosted by Geological Survey of NSW and supported by the University of Newcastle on Monday afternoon will give participants the opportunity to learn and ask questions about the evolution of the coastline over millions of years.
It will complement a coastal geotrail app that will also be launched this week.
"Newcastle has some of the best coastal geology in the world and this new geotrail allows NSW residents and visitors an opportunity to view the spectacular scenery while at the same time learning how to interpret and understand the ancient landscapes of the Newcastle area," Professor Ron Boyd from the University of Newcastle said
Deputy Premier John Barilaro said the geotrail was one of three already available in a planned network of geotrails the government is rolling out.
"This fantastic initiative during National Science Week allows participants to use hand held audio and visual guides in the world's most famous museums and art galleries and the geotrail app provides a similar experience, Mr Barilaro said.
"The geotrail showcases hundreds of millions of years of geological history and with the touch of a screen, users can discover facts about the Port Macquarie and Newcastle coastlines and journey into the Warrumbungle volcano.
"Two further geotrails are in development in far western NSW and each is unique, covering local geological highlights and historic and cultural facts."
Parliamentary Secretary for the Hunter Catherine Cusack said the webinar combined with the app was a unique opportunity to bring together science, history, culture and the beauty of the natural landscape.
"There are many intriguing clues to the geological and cultural history of this region visible in the rocks along the Bather's Way coastal walk, including massive volcanoes and ancient forests, the opening of the Tasman Sea between Australian and New Zealand and evidence of Awakabal and European use of the rocks and coal seams that underlie the city," Ms Cusack said.
"I encourage everyone living in and around Newcastle, the Hunter and beyond to register for the webinar for this unique chance to pick the brains of our local scientists."
In addition to the app, a free Newcastle Coastal Geotrail brochure is available at the new Newcastle Visitor Information Centre, located in the former Civic Railway Station at 430 Hunter Street, Newcastle.
