This is an EarthCache and has special requirements for logging it. You cannot log a Found It without responding to the logging requirements set out below.
Only one find claim per Message. Each Geocacher claiming a find must submit an individual response. One team can not lodge a response on behalf of a group of people.
Hopefully, after visiting this site, you will have an expanded appreciation of the wonders of our natural environment, and recognise that the environment here has a rather rare geological feature.
The Geology
A jump-up is a solid-rock feature similar in many respects to a Mesa, which has resisted erosion throughout a period of deep weathering that has surrounded much of the countryside.
Dominating the flat countryside north-north east of Longreach is a jump-up known as Cassidy Knob at an elevation of 213 m above sea level.
140 million years ago
Sea levels rose, and much of inland Australia became submerged. The actions of the sea covered the ancient landscape in sediment such as silt, sand, mud, and gravel, emphasizing the vast flatness you see today. The layer created is called the Great Artesian Basin and trapped within the sandstone is an important groundwater supply
110-100 million years ago
Australia still sat well south of the equator, at latitude South 55 degrees. However, it was slowly travelling north as violent volcanic eruptions and movements in the Earth's crust tore eastern Gondwanaland apart.
98-95million years ago
Australia continued its slow drift northward 45 degrees below the Equator, gradually approaching the Tropic of Capricorn. The climate became warmer and the last inland sea retreated, leaving behind swamps and luxuriant rainforests in Queensland's outback.
90 million years ago
The Longreach area was a swampland and sat roughly 100 metres higher than where the flats rest today - approximately level with the top of the Lookout.
8 million years ago
Global drying and cooling continued to alter the region drastically. Rainfall decreased and the swampland surrounding Longreach dried up. Wind and rain stripped back the sedimentary cover leaving a flat landscape interrupted only by the occasional jump-up.
The Observation
Your climb will take you to the top of the Knob. About half-way up you will come across a rocky outcrop upon which someone has emblazoned the number 256 in white paint. This is your first observation point.
Continue to the top and across to the other side - there you will see some more white paint graffiti commencing with the letter Y. At this point you need to turn around so that a rocky pillar with a hole in it (as per the photo) is on your right-had side. Looking at the rocks in front of you becomes the second observation point.
The Logging Task
First Observation Point (Rock with 256)
- In the description above there are two words which describe this rock. They are s__________ and s____________
- To the left, and above the number 2, are two different "features". What are they?
Second Observation Point
- The rock face you are staring at is not as "smooth" as the rock face at the first observation point. It has a different texture (the size, shape, and arrangement of the grains). (a) What size "grains" can you see here? (Any measurement basis acceptable - e.g. width of my smallest finger). (b) How do you think they might have got there?
- What process has caused this jump-up to remain (more or less) as it is now?
- What evidence is there that this process might still be happening?
- Take of photo of yourself OR your GPS to show a view of GZ similar to the one above. Include it in your message, but please do not post it in your log, it might give too much away.
When you have your response to the above questions, please, if possible, Message us, using the link at the top of the page underneath the name of the Cache. We prefer the Message method, as apparently, we don't respond to emails very well, but messages we do. We will contact you by Message once your Message has been received.
But please log your Found It 
in the meantime, and just say that you have Messaged your answers to the CO. We do reply to all logs within a reasonable time, and if there is a problem with your answers, we will ask you for further clarification.
Happy Earthcaching!
