These Stone have had many names and myths attached including Breeding Stone/Mother Stone, Hagstones, Growing Stones. This type of stones have been believed to breed, move, have feelings, ward off evil, and pop up from nowhere in fields. This caused some fine examples to be destroyed until in AD 601 Pope Gregory decreed pagan idols and myths should be sanctified by incorporating them into the fabric of the church.
All puddingstones have things in common (such as mineral composition), but they can look very different. The age has never been proved, but it is thought to be about 50 million years old. Puddingstones are a natural rock called conglomerate with an unusual history – a story of extremes. In fact, puddingstones are just one type of deposit that is often called sarsen, but that geologists call silcrete.
Flash floods carried pebbles and sand in broad river channels. The water quickly drained away and hot winds blew quartz dust between the grains encouraging crystals t grow as it dries. This forms a tough cement and hence a very hard rock.*
To claim this earth cache please email my via my profile the answers to the following questions.
A ) Explain what happened to make the round flint stones and sand on the dried riverbed became a layer of rock.
B) Explain why and how the Ice Age effected the Puddingstone 2.6 million years ago.
C) Choose an approximate 1x1 foot area and describe what you see then estimate how many different rock/grain types are present?
Optional: Post a photo of your visit to encourage other visitors.
