It is a Geological Wonder!

~450 Million years old. It consists of Limestone, which is Ordovician in age, from the Red River Formation.  At the time the sediments were deposited, it was in the setting of an ancient shallow sea.

This light coloured rock shows branches of burrows or trace fossils of those past sea creatures burrowing in the sediment of the old seabed.  Visible organisms, such as corals, sponges, gastropods, trilobites and algae can also preserved in this soft, limey, muddy rock.
