Today I managed to explore and observe an exposure of the Queenston formation up close here in Hamilton, Ontario. I chose a site along the Red Hill Valley Expressway that was easy to access and get down to for a close look. The creek is right next to the highway. I have always passed by this exposure and anticipated the day I'll be able to observe it.
The Queenston formation is the last Ordovician formation in south-western Ontario before the rocks hit the Silurian age. The Queenston is what overlains the Georgian Bay formation, the formation I use to hunt in frequently in Toronto, Ontario.
This is Red Hill Creek as it passes by next to the Highway.
