The population of Newnes on the 18th June 2017 swelled to about a thousand or 1018 including the Mudgee bush walkers. Yes, we had unwittingly chosen the one weekend of the year when the Glow Worm Tunnel marathon was in full flight, to visit the fascinating ruins of the hundred year old, abandoned Commonwealth Oil Corporation torbanite (oil shale) processing complex perched on the steep side of the Wolgan River Valley. The camping grounds were a tent city, and there were marshals directing us where to drive and where to park.
Morning tea provided the opportunity to catch up with some “old” friends, particularly the Kandos members who we hadn’t seen on a walk for a little while. The walk started at the river crossing, and we dodged the runners as we made our way across the stepping stones
to the industrial ruins track. These are a lovely example of the bricklayer’s craftsmanship. They certainly built things to last in those days.
The ruins track zig zags back and forth across the slope, supported by very substantial stone and brick retaining walls. On terraces descending the slope, the industrial complex is distinguished by what remains – evocative footprints, crumbling foundations and atmospheric ruins, all being reclaimed by the bush. The prevalence of circular building designs was striking. The information boards told us we were looking at the remains of brick kilns, paraffin sheds, a distillation plant, and numerous other components of what was one of the largest shale oil production schemes in Australia. We sat on some of these old foundations to eat our lunch and enjoy the view through the trees across to the other side of the valley, with the sounds of the Wolgan River flowing below.
The range of products created at Newnes included crude oil, paraffin, benzene, naptha, kerosene, lubricating oil and greases. Coke was produced for use on site as well as being sold in Lithgow.
An impressive feature was the long steep brick stairway leading down from the shale retort area to the remains of the distillation benches where the brick lined flues were still recognisable.
This walk was thoroughly enjoyable – a great combination of spectacular scenery, historical interest and very pleasant bush land. Thanks to all who came along and made it a great day.
