The Southern Lost City is an amazing place with many and varied sandstone pillars. They can be viewed from a distance or from very close up. This city was created and shaped by weathering. Its foundations were built as sediments washed into the sea about 1500 million years ago. As layers of sand accumulated under the sea they formed into hard sandstone. Over millions of years the sandstone has gradually cracked and these cracks have become gradually bigger. As joints became chasms, pillars of sandstone began to take shape.
There is a 2.5 km loop walk that starts from GZ and takes you alongside the formations and then leads between them so each can be admired as they are all very different. The walk continues along the ridge top and down between the pillars again and back to the start. This is absolutely a stunning place and has to be seen to be believed. Morning is the best time to walk and for photos.
When you go walking please remember to wear a hat, use sunscreen and take plenty of water. You will need a camera to get those amazing photos.
Camping is available and toilets are in the camp area.
You may log your find at any time but must email the answers to the CO. Do not put them in your log.
1. At GZ you are standing on sand. What was it originally and where will it end up eventually?
2. What has affected the cracks in the sandstone to enable pillars to form?
3. Sandy sediments were deposited on the seabed, accumulated. compacted and were cemented into sandstone by what and how was this "cement" formed?
4. What happened when the earth was uplifted?
5. What happens when the sandstone pillars are weathered and carries away?
6 .Facing west from the lookout area on the loop walk, what is the predominant geological feature and what is its name? You may like to post a photo of yourself or your GPS with this feature in the background, but it is optional.
We hope you enjoy your visit to this area.
