Geocache Description:

An Ice Age Landscape: Colemere

Anyone perusing Ordnance Survey maps of the northern parts of Shropshire will quickly realise that there is an unusual density of lakes, pools and mosses in the area. Names such as Pikes End Moss, Whattall Moss, Sweat Mere, Colemere, The Mere and Berrington Pool litter the map. Further study of neighbouring maps shows that these features also occur across county borders and into Cheshire, Staffordshire and Clwyd. Faced with this unusual preponderance of "wet" landscape features many people will ask themselves why are there so may of these pools and mosses here?

For the answers as to how Colemere was formed we need to step back in time about ten to twelve thousand years ago, when the last ice age retreated from the area. The vast ice sheets had carried huge amounts of sand, gravel and rocks across the country. This material had been dumped as the ice sheet retreated, leaving a loose mix of sands, clays and rocks. Next, there was a small re-advance, when colder conditions temporarily returned. This caused the ice sheet to push south again, piling up the glacial deposits in front of it, rather like a massive bulldozer moving across the landscape.

As conditions warmed once again, the ice sheet melted and retreated northwards. As this happened vast quantities of materials were washed out from the ice sheet and deposited over and around the previously "bulldozed" up material. The result was a great deposit of materials we call a glacial moraine and it is this feature that is responsible for the formation of the Colemere we see today.

Over the thousands of years since the moraine was formed, it has weathered to form the hummocky landscape now so familiar in parts of Shropshire. Good examples of this landscape are around Colemere and Whitchurch. Ideal for the formation of meres and mosses, the undulating landscape provided basins in which pools could form. In places, lenses of clay deposited within the moraine would hold up the water table, so that pools quickly formed in some hollows in the landscape. Some pools remain today as the meres we know so well, whilst others gradually filled with the remains of dead vegetation to form marshlands, or where acidic conditions prevailed, they would form peatlands - the mosses.

At the given co-ordinate's you will find an info board from the board please give me the answer to the following Question.
