It's been snowing all day here, starting with wet snow, almost rain, and gradually getting colder, so now the world is quite white again. And that first layer of wet snow from this morning is an icy undercoating - driving is quite bad this evening. But back to my geology hike...
Bet you don't know what this is! It's a 'Pentamerid' fossil, the diagnostic fossil of the Fossil Hill Formation. And yes, I did get to see this on our geology hike at Boundary Bluffs, Cape Croker.
Why is it of such interest?
In a few places near the Beaver Valley, this layer of the escarpment contains nodules of chert which were used by caribou-hunting native peoples after the ice age 10,000 years ago to make arrowheads, spearheads and stone knives. That's a MUCH more intriguing story than merely seeing the geological formation. I'm pursuing that story when I get the chance, and perhaps sometime in the future I can share that too. At least I now know what this formation looks like.
