As Australia drifted northward, 20-30 million years ago, it passed over one of the Earth’s hot spots, causing volcanic activity. Molten material formed the Mount Warning shield volcano and high rainfall created a myriad of streams and rivers which eroded the volcano into its present shape – one of the oldest calderas in the world. Fertile volcanic soil, high humidity and rainfall provided all the elements for the subtropical rainforest to thrive ( some of this reproduced, with permission, from the information board at Mt Warning). It is one of the Gondwana Rainforests and you are surrounded by ancient trees, dripping with moss. I think it is a good candidate for this week’s photo challenge: layered – from the lava-rich soil, littered with decaying leaves making your ‘twisted’ way up to the tree tops, trickling over shades of green and brown.
Tweed Heads has long conjured images of surf, sun and excitement. It’s nearness to the Queensland border and Coolangatta make it a popular holiday destination. But I had not known that the Tweed Valley, shared by both New South Wales and Queensland, was the site of an ancient volcano and that Numinbah Nature Reserve is at the base of this layered caldera?
The Wollumbin National Park, formally Mt Warning National Park, was renamed in recent years to reflect the importance of the lava plug, that is Mt Warning, to the local Aboriginal People, including the Nganduwal, Galibal, Gidhabul, Bundjalung and Widjabal. Many of their Dreaming stories involve the monolith.
There are many walks to choose from and an information booth at the entrance to the park, giving detail, advice and options. We parked at the entrance to the park and walked to the Lyrebird track, which was quite short, but beautiful. The path was firm and bitumised in parts, and we crossed Breakfast Creek and made it to the lookout. If I visited again, I would do a longer walk, but the traditional owners prefer that people do not climb Warning.
I’m partial to walks through a rainforest – it’s good for everyone, and everything, if we are careful where we tread and what we leave.
There are excellent facilities – toilets and picnic areas. Take a hat, camera and water. Good walking shoes are not necessary on the Lyrebird trail but would be needed on others. Sunscreen and insecticide are useful, but remember the environment if you decide to dip in a limb.
