The second of two earthcaches in Brabyns Park relating to erosion processes
Please note that this is an Earthcache; a find will only be accepted if the Logging Requirements have been met. 'Finds' without an appropriate e-mail WILL be deleted for obvious reasons. The CO receives many e-mails each week, via three different methods; the latest from Groundspeak called Messaging is not fit for purpose so please submit your Logging requirents via the e-mail option on the CO's Profile. Also if you are sending on behalf of other people besides yourself please make sure that this explained, or I will delete unexplained 'Finds' and as a result receive abusive e-mails
The view looking north from the car park
Several local features have appeared over the last 10000 years as a result of erosion of the Upper Carboniferous in the area. The location of these features was determined by land masses such as Brabyns Brow. These land masses caused obstructions to easy flow of the river Goyt and resulted in deposition of sediments eroded from rocks or other sediments upstream of the Park. This process has taken place at several times over the post-glacial period. Probably the most striking of these is the large area of terrace now hosting all the football fields in the Park. The land to the east of the river in Marple Bridge is also covered in glacial sediments older than the Brabyns Park Terraces and disguises the eastern side of the river channel. Just south of the Park is Town Street in the village of Marple Bridge. From Town Street you can see that the River Goyt flows through a deep rocky ravine before opening out into the wide expanse of the Park. Much of the erosion in this area is extreme for even the most swollen of winter rain and owes its origin the the glacial melt waters of the last ice age
To log this Earthcache:
1. How many flood plain terraces are there in the Park?
2. Explain why there is a large difference between the width of the gorge as seen from Town Street and that in the Park.
