This series of caches is a long term legacy of the popular 2014 White Cliffs Walking Festival week. Over a thousand people attended a multiple choice of events, tailored to suit everybody. This is the first time that Geocaching has been provided by Ramblers and featured in the programme.
This is the nineteenth cache in a series of 25 that have been placed along two National Walking Trails, The North Downs Way and The Saxon Shoreway from Capel le Ferne to Dover. The caches have been set with permission from Natural England and The White Cliffs Countryside Partnership. Some of these areas are set in areas of SSSI. Please avoid disturbance of plants and animals.
The local Ramblers celebrated their 25th anniversary in 2014, so that is why 25 caches have been set. They include a bonus cache called ‘Celebrating 25’. Clues for this special cache are hidden in this series. Don’t forget to write down the details as you find them and you will have the co-ordinates. This cache is hidden ‘somewhere’ in our spectacular White Cliffs countryside.
If you find all 25 caches including the bonus you will qualify for a unique Harveyjj souvenir for your public profile.
These cliffs are composed mainly of soft, white chalk with a very fine-grained texture, composed primarily of coccoliths plates of calcium carbonate formed by coccolithophores single celled planktonic algae whose skeletal remains sank to the bottom of the ocean during the Cretaceous and, together with the remains of bottom-living creatures, formed sediments. Flint and quartz are also found in the chalk. White cliffs like these in Dover are also found on the Danish islands of Møn and Langeland and the island of Rügen in Germany. In a 2005, the cliffs were named as the third greatest natural wonder in Britain. The cliff face continues to weather at an average rate of 1 centimetre (0.39 in) per year, although occasionally large pieces will fall. This occurred in 2001, when a large chunk of the edge, as large as a football pitch, fell into the channel. A further large section collapsed into the English Channel on 15 March 2012.Visitors are, therefore, urged to remain well away from the cliff edge. The cliffs themselves were formed at the same time as the Straits of Dover, by ice-age floods. Chalk is a soft, white, porous sedimentary rock, a form of limestone composed of the mineral calcite. Calcite is calcium carbonate or CaCO3. It forms under reasonably deep marine conditions from the gradual accumulation of minute calcite plates (coccoliths) shed from micro-organisms called coccolithophores. It is common to find chert or flint nodules embedded in chalk. Chalk can also refer to other compounds including magnesium silicate and calcium sulfate. Chalk has greater resistance to weathering and slumping than the clays with which it is usually associated, thus forming tall steep cliffs where chalk ridges meet the sea. Chalk hills, known as chalkdownland, usually form where bands of chalk reach the surface at an angle, so forming a scarp slope. Because chalk is porous it can hold a large volume of ground water, providing a natural reservoir that releases water slowly through dry seasons. Due to its porosity chalk is studied in numerous geophysical experiments (reflection seismology).
