Please note, you will require a 4WD to access this earth cache otherwise it’s a long walk in from Litchfield park road.
We think you will agree that the Lost City has incredibly unique & intriguing topography, it's not hard to imagine Poseidon hanging out here, geo daughter kept imagining Ariel and Sebastian were sitting on a rock nearby, either way it’s super cool and we would like to share it with you while talking a little about the earth science around it. GZ is just a suggestion, feel free to explore and answer the EC questions in any part of the lost city, please note the D rating reflects the time it may take to adequately answer all of the required logging tasks.
This Earth Cache has been placed with the permission of the Parks & Wildlife Commission who have also complied some of the information below, we ask that you respect the area, taking only photos and leaving only footprints.
To properly appreciate the formation we need to look back at the foundations of today’s landscape
What are we looking at now?
Essentially Sandstone remnants, the lost city is the remains of a huge continuous Sandstone layer that capped the surrounding ranges.
As the diagrams above suggest, weathering has naturally occurred breaking the cap into the intriguing formation you see today.
Natural weakness in the Sandstone occurs in planes at right angles to each other. Cracks form along lines of weakness and moving water makes the cracks wider and deeper, as this process continues blocks of the more resistant sandstone are formed with the end result being what you see today, because no geological process is ever the same or straightforward there are also three other sedimentary rock types mixed into the lost city. We would also like to point out that there d in .
To log this Earth Cache we require you to consider the information presented to you in this Earth Cache, walk around and look at the area, perhaps you will need to do some research of your own, then message us with the following answers to the best of your ability;
1. From your chosen vantage point, what are the tree main colours you can see?
2. Find 3 of the 4 rock types mentioned, name them and describe the visual differences you can see?
3. Considering these rocks were originally underwater, how far above sea level are they now? (Altitude in meters.)
4. A photo of your team or GPS with the Lost City in the background, upload as many photos as you like we would love to see the area again and again. (Optional)
You are welcome to log your answers straight away to keep your TB's and Stats in order but please message us with your answers within 24 hours. Cachers who do not fulfil the Earth Cache requirement will have their logs deleted.
