Before you attempt this cache, please check the tide times. The tide comes in very fast here, faster than you can run, and you may find it impossible to escape up the cliffs if you get cut off! You cannot access the cache at high tide.
Until the last few years, this area of shoreline was covered by salt marsh but the natural movement of the channel of the River Kent has eroded the soil and vegetation and revealed the bedded rocks on the shore. The limestones here belong to the Park Limestone Formation, which lies on top of the Dalton Limestone Formation, seen at Blackstone Point to the north. They were deposited as limestone mud around 340 million years ago in relatively shallow water. The corals which were growing upwards were probably tipped over by waves in the shallow water and are now lying flat, or even turned completely upside down. You should be able to find both solitary and colonial corals on the tops of some of the flat-lying beds, which may be covered when the tide comes in. One of the really exciting discoveries here is a new solitary coral which has been given the temporary, and not very catchy, name of Siphonophillia nov. aff. benburbensis.
There are lots of branched colonial corals too, like these.
Please take photographs of any corals, or any other fossils that you find and attach them to your log. We look forward to seeing them.
When you find the cache, just unscrew it to reach the log. Please do not try to remove the whole container.
