This cache belongs to the SideTracked series. It is not designed to take you to a magical place with a breath taking view. It's a distraction for the weary traveller, but anyone else can go and find it too. More Information can be found at the SideTracked Website
About Manchester Central Station
The station was built between 1875 and 1880 by the Cheshire Lines Committee (CLC), and was officially opened on 1 July 1880. The architect was Sir John Fowler and the engineers were Richard Johnson, Andrew Johnston and Charles Sacré for the three companies which formed the CLC.
While it was being built, a temporary facility, Manchester Free Trade Hall Station (after the Free Trade Hall a landmark building nearby) was in use from 9 September 1877. It had two wooden platforms serving four tracks. When the station opened, the temporary station became Manchester Central Goods.
In 1963 building was Grade II* listed for its special architectural or historic interest.
At the given coordinates, you will find Manchester Central Convention Complex. On 7th September 2019, it’ll be the host location of GeocoinFest Europe 2019.
Bedding describes the layering that occurs in sedimentary rock. Bedding may occur when one distinctly different layer of sediment is deposited on an older layer, such as sand and pebbles deposited on silt or when a layer of exposed sedimentary rock has a new layer of sediments deposited on it. Such depositions of sediments produce a clear division between beds called the bedding plane.
A bedding plane is the line separating one layer of compressed rock from the next layer of compressed rock. The bedding planes are layers formed as the rocks were compressed under deposits formed above.
Locharbriggs (or Dumfries) stone was formed during the early Permian when Scotland was close to the equator and desert-like conditions prevailed. it was a popular building stone in the 19th and early 20th Centuries and is still quarried near Dumfries, Scotland. Locharbriggs Stone is composed of well-sorted quartz grains coated in iron oxide and cemented by silica. It also contains clearly defined bedding/lamination structures where clay minerals are concentrated. Locharbriggs is a durable stone and tends to weather by granular disintegration.
Weathering is the breaking down of rocks, soil, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms.
A form of weathering where the grains of a rock become loosened and fall out, to leave a pitted, uneven surface.
Grain size means the diameter of individual grains of sediment. It can be categorised using the Wentworth Size Class
PLEASE EMAIL OR MESSAGE ME ON MY GEOCACHING PROFILE WITH THE ANSWERS TO THE QUESTIONS. ONCE YOU HAVE SENT THE ANSWERS, YOU MAY LOG THE CACHE.
To log this EarthCache, please go to the given coordinates and answer the following questions.
1. Please look at the grains in the stone. Please measure one. Please classify the size using the “Wentworth Size Class”. (image attached under the Grain Size section)
2. Please describe the bedding planes you can see in the rock.
3. Please measure a bed you see in the rock. Using the image from the section “Beds”, name the bed.
