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 may not be able to access the cache at high tide.
The rocks here are limestones of the Dalton Limestone Formation, deposited in layers in tropical seas about 340 million years ago. In between the beds of limestone, you may be able to see thin layers of mud.
There are lots of fossils in the limestone, particularly corals of a number of different species. Around here, they are mainly solitary corals like this one.
If you could have seen one alive, it would have been shaped a bit like a small ice-cream cone living with its base embedded in the sea bed. The different species are identified according to the details of their internal structure. You may also be able to find what look like minute polo mints. These are crinoid ossicles
Crinoids are also known as sea lilies, though they are actually animals, and have a stem made of ossicles like this, piled on top of each other, with tentacles at the top.
We'd love to see some pictures of the fossils you find on your visit! Please post them with your logs - but do watch the tides!
