The Cove at Lulworth has been hollowed out in the cliffs by the force of the waves. It is nearly circular in shape being 1380 feet across at 21 feet deep at low water with a break in the side by way of entrance from the sea.

In the 'Good Old Days' Lulworth Cove was one of the chief centres of the smuggling trade along the south coast as owing to its peculiar conformation the entrance is practically hidden.

Tufa eggs for Easter, Matlock Bath, Derbyshire

Birds nest and eggs encrusted in tufa, Matlock Bath, Derbyshire. Photograph from the Geologists' Association 'Carreck Archive'

Original description: 'Tufa which also goes by the name of Travertin [Travertine] or Calcareous Sinter is a deposit of Carbonate of Lime thrown down by springs which flow through beds of limestone. In this case at Matlock these specimens are from lime obtained from the Carboniferous Limestone. The rain in passing through the atmosphere takes up Carbonic acid and assisted by humic acid from the soil when it sinks into the limestone dissolves portions of it away. When it comes to the surface again in the form of springs it loses some of the Carbonic acid and the lime is thrown down in the form of tufa and incrusting any object that happens to be present.'
