Grid Reference: TQ766518
The Upper Loose Valley displays a variety of interesting geological, geomorphological and hydrological features. This northeast-southwest section of the valley penetrates the Lower Cretaceous Hythe Formation (ragstone and hassock) that forms the dip slope of the Greensand Ridge and reaches down to the underlying Atherfield Clay. Here the clay forms an impervious layer and springs emerge at the junction. The clay was used in the construction of ponds to provide water power for industries, such as paper making and tanning, situated in the valley. Along the edges of the valley another local industry, quarrying, exploited the Ragstone for building material. [See details under the associated RIGS site at Loose Quarry, Quarry Wood.]
There appears to be evidence of Karstic weathering of the Ragstone, a feature that is rare in Kent and requires further investigation. Karst is a type of typography characterised by caves, caverns, dry valleys and underground drainage. Karst is the type location in Yugoslavia.
Access And Safety
The site can be viewed from the various public footpaths through the valley. The paths are well marked from The Quarries, Boughton Monchelsea or Loose Village.
