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.
A fascinating geological outcrop right on the ACT-NSW border.
Please note: adjacent to this cache there is a traditional cache called Wild Wild West, GCMVPJ. It is partially obscured by the icon for this cache, so please don't miss it. Wild Wild West is part of a series of 4 caches, this one being the western-most cache of the series in the ACT.
Shale is a fine-grained, clastic (composed of broken pieces of older rocks) sedimentary rock composed of mud that is a mix of flakes of clay minerals and tiny fragments (silt-sized particles) of other minerals, especially quartz (crystal structure - the second most abundant mineral in Earth's continental crust, after feldspar) and calcite (basically calcium carbonate crystals). The ratio of clay to other minerals is variable.
The colour of shale
Shales are typically composed of variable amounts of clay minerals and quartz grains and the typical colour is gray. Addition of variable amounts of minor constituents alters the color of the rock.
More on Shale
Shale rocks are those that are made of clay-sized particles and are have a laminated appearance. They are a type of sedimentary rock. Shale is the abundant rock found on Earth. They are usually found in areas where gentle waters have deposited sediments that become compacted together.
At GZ you will find a yellow Survey Marker. Look around you at the prominent rock formations. There are no granite boulders here, such as on nearby Mount Franklin. Instead you will find something completely different.
Respond to the following tasks:
*Describe in your own words, the type of rock prominent around the marker.
*Which geological features of the following description are obvious to you where you stand?
According to Wikipedia : The geology of the range comprises block-faulted granites and Palaeozoic metamorphic rocks. There are small areas of Tertiary basalt with buried river gravels and lake sediments. The typical characteristics of the range include low-relief high plains with steep margins and slopes and fault aligned river valleys with deep gorges and waterfalls.
*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.
Send your best answers to the above via the "Message this owner" link at the top of the page. Please don't send via email if possible - I don't deal with email very well.
For extra brownie points, include a close-up of the rock formation you found most fascinating.
Enjoy this wonderful spot.
