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.
While returning from a successful geocache find, I was "arrested" by what I saw at what is now GZ for this earthcache. I hope you are as fascinated as I was.
Karawatha Forest Park was protected by land purchases through the Bushland Preservation Levy and is one of Brisbane’s major natural areas. Council has also acquired land to the south and west of Karawatha Forest, ensuring that vital bushland links with Greenbank are maintained to preserve our significant flora and fauna.
The forest’s infertile soils and sandstone ridges were formed by continual cycles of mountain building and erosion over many millions of years. Some of the sandstone outcrops were laid down in the Triassic-Jurassic age when dinosaurs, not wallabies, grazed here. REF
Sandstone is a sedimentary rock that forms from cemented sand-sized clasts. A clast is a fragment of geological detritus (detritus refers to loose fragments of rock, minerals, and organic material that result from weathering and erosion), chunks and smaller grains of rock broken off other rocks by physical weathering. Geologists use the term clastic with reference to sedimentary rocks as well as to particles in sediment transport, whether in suspension or as bed load, and in sediment deposits. It forms when sand layers are buried under sediments of sand.
You will find a nice panorama of the sandstone outcrops in boulder-shaped form here.
But the sandstone at GZ is not in the form of "boulders" as we would normally think.
A Geological Note on Size:
The diameter of a grain is crucial for classification. For example, in the
Wentworth scale, particles are graded as boulders, cobbles, pebbles, sand, silt, and clay. For our purpose here, let's form these into three types: Large (boulders, cobbles, pebbles), coarse (sand) and fine (silt and clay)
Look around you and see if you can discover any evidence of the existence of sandstone. Examine it closely; run your fingers through the "soil", then answer the following three questions, and your photo:
- What type of rock is sandstone? (Sedimentary, Igneous or Metamorphic)
- Which word applies to the size of the grains you can feel with your fingers - large, course or fine grained?
- What natural and human interventions have caused the grains to dislodge from the sandstone?
- Take of photo of yourself OR your GPS to show a view of GZ. Include it in your message, but please do not post it in your log, it might give too much away.
The answers are you observations: message your answers to me via the Groundspeak message site (Link is at the top of this page). Your answers will be responded to.
PLEASE DO NOT EMAIL ME IF POSSIBLE. I don't deal with email very well. 
I will reply only via the Message section.
In the meantime, go ahead and log your find.
Happy Earthcaching!
