• Thames River Terraces – why is my garden so pebbly?
  • Glaciers north of Oxford and the impact south of the Chilterns
• The Warren – when dinosaurs roamed the land, we were under the sea
  • Geology, the watertable and transportation
• Sunken Lanes – connecting Caversham Heights heathland to the Thames water meadows
  • We will all have seen them but why and how do they form?
• Dry Valleys – Valleys without rivers in the Chilterns
  • Why are they there and why do they have the shape they do?
