The White Ferns of St Clair |
April 2015 I had a free Saturday and the weather forecast didn't look all that bad so I packed the car on Friday night for an early start. The mountain top was cold and windy when I arrived so I got right to work. A few hours of digging exposed a decent shelf and I lucked out when I found a nice section cleanly separated from the shelf. Another hour to free it from the overburden but worth it, a beautiful bookmarked slab. Many people consider the fern fossils found St Clair to be some of the finest in the world. This is one of the few places where one can find detailed white ferns on a jet black slate. The white (Pyrophyllite) is believed to be the result of a later replacement of the pyrite. Additional Info: Sadly the latest reports posted on the FossilForum.com have the St Clair site now closed to collecting.
Just a light spray with the hose the next morning.

This St Clair ferns are approximately 300 million years old
