When you arrive at the location you will see clear evidence of surface erosion to the area above the rock face. This recently became that unstable that part of the strata and the earth above it slipped and broke away causing a landslide. This has now recently been corrected and strengthened to stop further earth slips. Due to the nature of work carried out the detail of the strata is now clearly visible and very clean.
The rock you are looking at is a sedimentary type. Sedimentary rocks are formed by the breakdown of older rocks into smaller grains to form sediment through surface processes. Over time these are deposited, mainly with the use of water and build up in layers to form sedimentary rocks. In time these are buried to form sedimentary rock through the process of lithification. This process involves the sediment becoming cemented and then compacted to form the sedimentary rock. Common sedimentary rocks include Sandstone, Limestone and Mudstone.
The rock that is visible at this point is very common to the area and can be seen in lots of locations. At this location it is possible to see the layers of different coloured deposits in the rock face.
Now for the fun part.
PLEASE ENSURE THAT YOU VIEW THE GZ FROM THE STATION CAR PARK. In order to log a find against this Earthcache please complete the following questions/tasks and send your answers via email through our profile.
Any finds logged without us receiving an email will be deleted
1. What is the name of the rock present in the rock face
2. What colours can you see in the rock face
3. Estimate the height of the rock face from its highest point to the ground
4. Please post a photo of yourself/GPS with the strata in the background to celebrate your visit, this is totally optional
Please enjoy your Earthcache experience and happy caching!
