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
A Kame is one of a series of glacial features visible on the ground and often passed by unnoticed. Kames, Eskers, Drumlins, Terminal and Lateral Moraines are varieties of similar features. Nearby Earthcache GC413NR Ludworth Intake SSSI highlights a glacial channel where a large amount of material was removed from the landscape by glacial action over 15000 years ago. This Earthcache deals with what happens to material torn from the land mass and transported by the glacier.
Global warming is not new. The temperature of the earth is constantly varying, and even in the last ice age there would have been times of considerable melting of the ice cap followed by periods of freezing; the time scales are much greater than we normally consider. The net result would have been that of non-uniform distriburion in the ice of glacially eroded rocks of non-uniform composition. As the glaciers melted and retreated northwards the material being transported would have been deposited in a way reflecting its distribution within rhe glacier just prior to the ice melting. In some places there would be fairly uniform lenses of boulder clay, in others large erratics, and in the case of Kames a fairly regular dome shape. The shape of the deposited material could have also been as a result of the flow of melt water and result in a linear deposit known as an Esker. We tend to focus on the large depths of ice which were present at the height of the glaciation period, but as the ice thinned land would appear from under the glacier the edges sometimes delineated by lateral moraines, and the snout of the glacier similarly by a terminal moraine. ( A particularly fine example of a terminal moraine is described at length in the Cumbrian Earthcache GC1Z3ZW Seamill Moraine).
Here beside Shiloh Road are two Kames of approximately similar size. The first is at the listing coordinates and the second is at waypoint S1. Their identification was possibly due to mechanical erosion by cart wheels cutting through a soft structure before the road was metalled.
Logging requirements.
1. To demonstrate the carrying power of the ice flow, use an approximation for the weight of the Kame,as 50% HeightxAreaxDensity Use 2.5 as the density of the Kame material in grams per cc.'
2. The composition of the Kame reflects its origin and not its area of deposition. How might that affect the landowner/farmer? 3. Do you think the structure to be Kame, Esker, Drumlin, Terminal or Lateral moraine and why?
