Trapped in the box EarthCache

An earthcache highlights geological features of the planet that we live and play on. At the listed co-ordinates there is no physical cache.

The Co-ordinates will take you to a memorial, where you will be standing in an alleyway with three large sandstone blocks on the roadside, and leading into a circular area where there is a large sandstone pillar in the middle.

Although coal can be found all over Australia, the majority comes from the eastern states, of Queensland, New south Wales, and Victoria

Coal is a combustable rock, of organic origin, which is mainly carbon, and is formed by accumulated vegetable matter, and a small amount of inorganic matter, that has been altered by decay, and various amounts of heat and pressure during a course of millions of years.

Coal comes in different colours, with black coal having a higher energy, and lower moisture content than that of brown coal.

Interlayered with thin layers of shale, siltstone, or sandstone, coal is found in seams, or beds, ranging anywhere from less than a millimeter, to many millimeters thick, making open cut mines a preferred way of extracting it from the ground, rather than trying to follow the seam in a tunnel. There is no public access to either, as they are considered to be extremely dangerous places

After the coal is extracted from the ground, it is crushed and screened, and often then washed by immersing it in a liquid of high specific gravity, in which the coal floats, while the other heavier minerals sink and are then discarded.

To claim a find on this cache you must answer the following questions and submit the answers via email to the cache owner BEFORE logging a find.

Q1. Standing at GZ, (in the alleyway) you will see in the garden bed and in it there are three upright features, what is the rear upright feature composed of ?  You can go outside the alleyway and look at this feature from the other side where it then becomes the front feature.

Q2. What is the average size of the individual pieces, that are on the upright feature mentioned in question 1, and how many do you think are here.

Q3. What is the texture of the pieces on the upright feature mentioned in question 1, and why do you think they are this texture.

congratulations to igotahunch, who has submitted the correct answers first, and obviously shows how keen he is by going out to GZ in the terrible storm this afternoon, you obviously are a dedicated geocacher
