Centenary Walk: Richmond Park, Kingston Hill and Wimbledon Common
Members of the GP demonstrated the plasticity of the London clay, terrace gravels, 'bunter' pebbles (transported by tributaries from the north) veined quatz, and lower greensand churt (used as a building stone near Guildford);
In the afternoon we crossed the A3 and the Beverley Brook to walk up to Wimbledon Common. Here we are looking at Caesar's well, later visiting the Queens Mere before reaching the windmill.
En route we had an opportunity to discuss the various granites we had seen (around the well) and their provenance. At the excellent Windmill Museum there is a history of windmills and we noted the materials used for mill stones including the expensive and highly prized French quartz.
