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.
The earthcache title should give you a pretty good idea of where this earthcache is. 
So while you are admiring what you see at GZ, please read through the following information screed:
Igneous rock is that which is formed underground – magma or lava – which then cools, either underground or on the surface, and becomes solid igneous rock.
Sedimentary rock is that which is formed on the surface – usually by the deposition of rock or organic particles, ‘cemented’ together to become sedimentary rock.
Metamorphic rock is that resulting from the (usually) underground transformation/metamorphism of any existing rock to a new type of rock - metamorphic rock.
Of course, the latter may also be broken down by various processes to become sedimentary rock. And so on it goes.
But returning to sedimentary rock: it is, by definition, composed of many smaller rocks of one type or another – right down to sand and mud.
This ‘act’ of a solid (however large or small) coming out of solution is called Precipitation. When layered, it is called Deposition.
The sediment can be pebbles, sand or mud. Actually, from the smallest size, increasing in size, they are clay, then silt, then sand. Pebbles are anything larger than 2 millimeters.
[This is a generalization. One source lists 14 size levels of differentiation]
But HOW IS IT HELD TOGETHER?
In other words, how does the loose sediment get turned into hard rock?
As layers are piled one upon another, the sediments beneath are buried, sometimes by hundreds of metres of sediment above. The weight of these layers compacts (squashes down) the sediment grains. This is compaction.
But it not just rock alone. They are accompanied by minerals which also get trapped in the spaces between the rocks as they are layered. These minerals gradually cement the rocks and particles together.
Common cementing materials are calcite, silica, iron oxide and clay minerals.
When the process is “finished”, the clay becomes Shale. The silt becomes Siltstone, and the sand, Sandstone. The Pebbles are usually surrounded by a matrix of sand or mud, and are called Conglomerate.
In nature, it is not easy to come across these different types of rocks. But when a bulldozer or grader exposes the rock by removing surface vegetation and soils, it’s amazing what you can discover.
Take what has happened here at GZ, where the rock is exposed.
From your reading of the above, how would you describe the rock type? Is there any shale, or siltstone? Any sandstone? Can you see anything that might be conglomerate?
To record a find, you are required to locate just one spot on this exposed surface that has something unusual that you can comment upon, and take a photograph of it with one of your fingers included to help you describe what you see in terms in size, and tell why you choose to describe that particular part of GZ with its unique geological features. You do not need to get technical - just describe what you see.in your photo.
Include your photo and description together in your answer to the CO.
PLEASE do not include photographic materials in your cache page log.
Answers will be dealt with in a timely manner, but please log your find as soon as you can.
